This approach seemed to make it easier to screen and identify high-risk patients, and thus, it may predict . What is the shape of C Indologenes bacteria? bouquinistes restaurant paris; private client direct jp morgan; show-off crossword clue 6 letters; thermage near illinois; 2012 kia sportage camshaft position sensor location Overall, most cases of non-Hodgkin lymphoma are considered very treatable. Springer Nature remains neutral with regard to jurisdictional claims in published maps and institutional affiliations. 2015 Jul;170(2):185-91. doi: 10.1111/bjh.13420. The PET scan also looks at the rest of the body and can identify if the cancer has spread. Stage III-IV: There is cancer in lymph node areas on both sides of the diaphragm (stage III), or the cancer has spread throughout the body beyond the lymph nodes (stage IV). 2022 Sep 21;11(19):5541. doi: 10.3390/jcm11195541. Intravenous contrast media was given in some studies. Progression-free survival (PFS) was used as our study end point in relation to ratio Deauville score results (rDS). Deauville is a posh seaside resort in Normandy, France. In the DS interim negative group, male children were 50/65 patients (representing 77% of interim negative group), while in the interim positive group, male children were 17/24 (representing 71% of interim positive group). Deauville score versus ratio Deauville score in the interpretation of interim 18F-FDG PET-CT and in prediction of outcome in children with FDG-avid extra-nodal lymphomas. The scoring just says "if there is a lymph node brighter than spleen then +2, or +1" if x is brighter than y then add 1. A Deauville score >3 is the most optimal cutoff for interim PET with advanced-stage HL to increase PPV if intensification of therapy is planned, whereas a cutoff <3 is desirable for nonbulky early-stage HL to enhance NPV. Eur J Nucl Med Mol Imaging 42(4):623633. Three patients had biopsy-proven relapses 3-9 months after completion of chemotherapy. These findings are different from results of most of published papers in this context that can be explained by the non-homogeneity of our sample regarding pathological subtypes and stages. Patients with negative 5p-DS and patients with rDS<1.25 had a similar 3-year PFS (87%). Again, at the end . https://doi.org/10.1371/journal.pone.0211649, Article 2022 Mar;49(4):1311-1321. doi: 10.1007/s00259-021-05581-z. The .gov means its official. Written informed consents were obtained from all parents. Initial pre-treatment and interim FDG PET/CT were interpreted and compared with each other by two experienced nuclear medicine physicians blinded to patients outcome with at least 8-year experience in the field of PET/CT interpretation. 25 Patients with Hodgkin lymphoma with a Deauville score of 1 or 2 have been shown to . In particular, international guidelines recommend using the Deauville criteria to assign patients a score of 1 through 5, indicating their response to treatment as revealed by PET imaging. In most situations where standard treatment will be given, a Deauville score (DS) of 3 represents a complete metabolic response (CMR). A Deauville score of 4 indicates that the lesion FDG uptake is moderately greater than the liver activity, whereas a Deauville score of 5 indicates that the lesion FDG up-take is markedly greater than the liver up-take, typically 2-3 times more intense (Figs. After 4 treatments or 2 cycles of ABVD, they achieved a complete remission with a Deauville score of 1. Scores of 1 and 2 are considered to be negative and 4 and 5 are considered to be positive. survival. Bookshelf Provided by the Springer Nature SharedIt content-sharing initiative. 2. The aim of our study was to evaluate the prognostic role of the ratio between the SUVmax of the hottest target residual lesion and liver SUVmax (rPET/rDS) in children with FDG-avid lymphomas undergoing interim FDG-PET/CT during the first-line chemotherapy and to compare rPET with 5p-DS. J. Nucl. PMC PET/MR demonstrated good intermodality agreement with 18 of 20 interim Deauville scores concordant (Deauville 2: n = 11, Deauville 3: n = 7), = 0.808 (P < 0.001) (Tables 4). To the left: Initial study shows metabolically active FDG-avid osseous infiltrates at manubrium sterni and DV7. Accurate interpretation of early response evaluation PET (interim PET) is crucial for achieving the best management strategy for lymphoma patients; however, it is still a subject of ongoing debate. The survival outcome in the rDS group1.25 (our selected cutoff value) was significantly better than that of rDS>1.25 with a 3-year PFS of the former group 87.6%, while the 3-year PFS in the latter group was 60% as illustrated in Table 10 and Fig. However, none of the semiquantitative parameters were correlated with rDS. -. Response to therapy in interim negative and positive group. The diffuse large B-cell lymphoma prognosis calculator estimates the overall & progression-free survival with the use of the revised IPI score for lymphoma. Vulcan Productions produced documentary films, television programming and virtual reality experiences that drove awareness around environmental and social issues. Overall, 79% and 91% of patients achieved a CMR in FLs and the BM, respectively. Theres a perception among patients that anything with uptake is abnormal. Patients received an intravenous injection of 5.55 megabecquerel (MBq)/kg (0.15 milli-Curie/kg) body weight dose of 18F-FDG (minimum dose, 74MBq (2mCi). Evens A, Kostakoglu L. The role of FDG-PET in dening prognosis of . Leuk Lymphoma 50(8):12571260. Federal government websites often end in .gov or .mil. Is Clostridium difficile Gram-positive or negative? Prognostic value of complete remission status at end-of-treatment FDG-PET in R-CHOP-treated diffuse large B-cell lymphoma: systematic review and meta-analysis. PET/CT is routinely used also for the end-of-treatment evaluation of response to the therapy according to the Deauville score comparing the FDG uptake in the target lesion to . Bone marrow was considered to be positive for active lymphoma if single or multiple foci of clearly elevated FDG uptake within the bone marrow were present, while diffuse bone marrow activity/uptake was considered negative. The brighter the nodule appears on the PET scan, the more likely that it is cancer. We recommend making further studies with larger sample size, with more homogenous samples regarding histopathological subtypes and chemotherapy lines to confirm these results. Many studies illustrated some disadvantages for that qualitative assessment, including its dependence on the amount of administered activity and body weight and high liability to inter-observer disagreement. Our tool serves as a simple DLBCL prognosis calculator - read on to find out more about the diffuse large B-cell lymphoma staging, signs and symptoms. From the 89 children with proved extra-nodal lymphoma, 66 (74.2%) were males and 23 (25.8%) were females. Most articles have considered the utility of FDG (fluorine-18 combined with deoxy-glucose) which is the most used radiotracer in clinical practice. On a retrospective study conducted by Toladeno et al. https://doi.org/10.1542/pir.2016-0152, Article Epub 2015 Apr 1. [13] found that extra-nodal involvement in more than 2 sites is a predictor of early and late response to therapy. The visual interpretation of this study using 5P-DS was positive (score 4) as left femoral activity was higher than that of liver, while it was negative using rDS (rDS=1.05) which is less than the cutoff point (liver max~2.5). Score 3 should be interpreted according to the clinical context but in many Hodgkin Lymphoma patients indicates a good prognosis with standard treatment. It can also show up in other areas of your body. pneumonitis is FDG-avid and can persist for years after therapy. The ROC analysis for rDS as a predictor of progression showed an optimal cut-point of 1.25. 1-2 points: Prognosis, Good (4-year PFS 80%, OS 79%) 3-5 points: Prognosis, Poor (4-year PFS 53%, OS 55%) The R-IPI doesn't recognize risk groups with a perceived B cell lymphoma survival rate of under 50%. A tumor marker (if applicable) may fall within the normal range. Among patients in partial remission or stable disease at day 30, the authors observed two subgroups with significantly different prognosis; patients with Deauville score (DS)4-5 and a concomitant reduction of standardized uptake value (SUV) mean had higher probability of long-lasting response than those with DS4-5 and an increase of SUV mean. Also, there was a significant correlation between the number of residual diseased sites at interim PET and survival which could be explained by its reflection of the aggression and widespread of the disease and consequently poorer response to therapy. Results: When Deauville 5-point scale (5-DS) scores of 4-5 were classified as a positive scan (denoted by DS [score 4]), there was no significant difference in progression-free survival (PFS) between I-PET positive and negative patients (P=0.151). Deauville score did not influence overall survival. The side effects of chemotherapy occur as a result of this damage. The scale ranges from 1 to 5, where 1 is best and 5 is the worst. The conventional surgical procedure for lung adenocarcinoma is lobotomy with systematic mediastinal CT. A contrast enhanced CT is recommended for anatomic staging and radiation therapy planning. Deauville. PET works by using a scanning device (a machine with a large hole at its center) to detect photons (subatomic particles) emitted by a radionuclide in the organ or tissue being examined. The blood glucose level should be less than 160mg/dl. The survival outcome in the rDS group 1.25 (our selected cutoff value) was significantly better than that of rDS > 1.25 with a 3-year PFS of the former group 87.6%, while . Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022. 2010;37 (10): 1824-33. I love to write and share science related Stuff Here on my Website. GIT and BM were the most frequently involved extra-nodal sites. https://doi.org/10.1007/s00259-014-2715-9, Van de Wiele C, Kruse V, Smeets P, Sathekge M, Maes A (2013) Predictive and prognostic value of metabolic tumour volume and total lesion glycolysis in solid tumours. MeSH Positive initial bone marrow biopsy, presence of B symptoms and the number of involved extra-nodal sites in initial PET, visual assessment of interim PET, and the number of residual diseased sites were significantly correlated with prognosis, while none of the semiquantitative parameters correlated significantly as illustrated in Table 8. Epub 2021 Apr 28. According to the Lugano 2014 guideline, patients with a Deauville score of 1-3 are regarded as negative of disease, while those with a Deauville score of 4 and 5 are positive of disease. Adequate hematologic function defined as all of the following . To the right: Interim PET-CT study shows complete disappearance of DV7 lesion with a still residual lesion at sternum with SUVmax~2.2. Each FDG-avid (or previously FDG-avid) lesion is rated independently: It is often stated that DLBCL patients who demonstrate a complete metabolic response (Deauville 1)but have a residual mass of greater than 2 cm are at an increased risk of recurrence. 2021 Feb;192(3):504-513. doi: 10.1111/bjh.16875. Articles are a collaborative effort to provide a single canonical page on all topics relevant to the practice of radiology. An improved image quality may affect visual scoring systems, including the Deauville score (DS), which is used for clinical assessment of patients with lymphoma. Prognosis for Stage IV Hodgkin's Lymphoma & Patient Expectations. Check for errors and try again. This study showed and validated that Deauville score of 4-5 of PET-CT imaging taken after full-course of R-CHOP chemotherapy with or without RT could predict recurrence-free survival and overall survival in DLBCL patients. Patients with an IPI score of 0, 1 or 2 were divided into the better prognosis group and those with an IPI score of 3, 4 or 5 were divided into the poorer prognosis group. The Deauville scale was established during a medical congress a few years ago. Oncol. Later, some studies started to discuss the benefit of using a ratio between semiquantitative parameters (e.g., target lesion and liver SUV) for interim FDG-PET/CT interpretation as an alternative to 5p-DS. Moreover, this study has some limitations including the small number of patients, heterogeneity of lymphoma subtypes, and first-line treatment modalities used that could affect the outcome. J. Nucl. Other tracers are also used in PET to image the tissue concentration. In previous studies,9 12 5-DS of scores of 13 were defined as negative scans, and scores of 45 were considered to be a positive result. Chi-square test (Fishers exact test) was used to examine the relation between qualitative variables. If the cancer is found in its earliest stages, the 5-year survival rate is 91%. Regarding our results, patients with rPET more than 1.25 had a worse prognosis than patients with rPET less than or equal to 1.25 with a significant statistical difference between both groups with a P value=0.009. Our study highlighted the prognostic value of both methods and shows that the rDS could be put in consideration as a more accurate prognostic factor in those children with lymphoma. The DS . What is lymphoma score? Of the 10 patients with an end-of-therapy Deauville score of 4 or 5, four had a diagnosis of relapse or refractory disease based on end-ofchemotherapy imaging alone. Positive positron emission tomography (PET) scan defined by the Deauville scale 3-4 and within 2 months of start of high dose chemotherapy prior to ASCT . Accessibility The total uptake in the brain is approximately 6 % of the injected dose. A PET scan is an effective way to help identify a variety of conditions, including cancer, heart disease and brain disorders. Google Scholar, Ng AK, Bernardo MP, Weller E, Backstrand KH, Silver B, Marcus KC, Tarbell NJ, Friedberg J, Canellos GP, Mauch PM (2002) Long-term survival and competing causes of death in patients with early-stage Hodgkins disease treated at age 50 or younger. Cookies policy. National Library of Medicine Part of Epub 2021 Oct 15. However, this is not always true and can cause unnecessary alarm and concern. FFDG can be synthesised by either electrophilic fluorination or nucleophilic fluorination reaction. What is the difference between parietal cells and chief cells? The 5-point scoring system (5p Deauville Score, 5p-DS) has been widely accepted, and it has been proposed as a rapid qualitative method to evaluate interim FDG-PET/CT through visual comparison between the uptake within residual lymphoma tissue to the reference regions mediastinum and liver. Please Note: You can also scroll through stacks with your mouse wheel or the keyboard arrow keys. What are the differences between a male and a hermaphrodite C. elegans? "Score 3 should be interpreted according to the clinical context but in many Hodgkin Lymphoma patients indicates a good prognosis with standard treatment." History. The Deauville five-point scale (Deauville 5PS)is an internationally-recommended scale for routine clinical reporting and clinical trials using FDG PET-CT in the initial staging and assessment of treatment response in Hodgkin lymphoma (HL) and certain types of non-Hodgkin lymphomas (NHL). It included 92 children with pathologically proved lymphoma. . In patients whose GIT showed diffuse activity, meticulous interpretation of other findings such as the presence or absence of bowel masses, accompanied nodal or extra-nodal lesions as well as history of inflammatory bowel disease is included for final suggestion. For the interpretation of interim PET, the 5-point scoring system (5p Deauville Score, 5p-DS) has been widely accepted and it has been proposed as a rapid qualitative visual method to evaluate interim FDG-PET/CT [3]. Multivariate analysis was difficult to be done because of the limited number of significantly correlated factors in the univariate analysis. PMD Score 4 or 5 with an increase in uptake from baseline and /or New FDG-avid foci consistent with lymphoma At interim or end of treatment *Score 3 in many patients indicates a good prognosis with standard treatment. Two-sided p values less than 0.05 was considered statistically significant. Correlation between various variables was done using Spearman rank correlation equation. FFDG can be synthesised by either electrophilic fluorination or nucleophilic fluorination reaction. When evaluated by the Deauville criteria, patients with an interim PET with a score of 1-3 (n=83) had a median OS and EFS of 104 months and 64 months compared to those with a score of 4-5 (n=16) who had a median OS and EFS of 19 and 11 months (p<0.001). This camera integrates a PET scanner with a dual-section helical CT scanner and allows the acquisition of co-registered CT and PET images in one session. Further, patients with 5-DS score 3 and high IPI were stratified into I-PET positive-, whereas . Vitolo U, et al. Graduated from ENSAT (national agronomic school of Toulouse) in plant sciences in 2018, I pursued a CIFRE doctorate under contract with SunAgri and INRAE in Avignon between 2019 and 2022. Score X: New areas of uptake unlikely to be related to lymphoma. The datasets used and analyzed during the current study are available from the corresponding author on reasonable request. Although slow growing forms of NHL are currently not curable, the prognosis is still good. Four patients had a Deauville score of 1-3, and none of the four had a relapse at 1 year. During the past 2 decades, 18F-fluoro-2-deoxyglucosepositron emission tomography (FDG-PET) has been found to be useful in providing information about the metabolic activity in patients with lymphoma and has been utilized in lymphoma staging [2, 3]. 2014 Sep 20;32(27):3059-68 Some types of lymphoma are more common in children and young people than in adults, and they can be treated differently. Pediatric lymphoma is a common hematological neoplasm, representing the third most frequent childhood malignancy [1]. In the multivariate analysis, DS was still a significant factor for recurrence-free survival [hazard ratio (HR), 3.840 and confidence interval (CI), 1.068-13.806; P = 0.039] and overall survival rates (HR 4.453 and CI 1.274-15.562; P = 0.019). Positive bone marrow biopsy was found in 25 patients, 10 of them were negative in interim PET, while the rest of them were interim positive. The ROC curve showed two cutoff values (1.25 and 1.40): the first value (Fig. Both 5p-DS and rDS were strong outcome predictors. This provides a number (2, 10, 20, etc.) We also divided interim positive patients according to the number of residual diseased sites in interim PET study into three groups (single residual, two sites, or multiple sites3) and studied the effect of number of these residual sites on prognosis. Chi-square test (Fishers exact test) was used to examine the relation between qualitative variables. The survival outcome in the interim negative group was significantly better than that of the interim positive group with a 3-year PFS of the former group 87.2%, while the 3-year PFS in the latter group has 67.4% (P value=0.002) as illustrated in Table 7 and Fig. Unauthorized use of these marks is strictly prohibited.

Duration of response is the time from response (R) to progression/death (P/D). A score of 4 or 5 is an indicator to consider escalating therapy. Increased FDG uptake values reflect the viability of cancer cells, and can be imaged and quantified using PET. [10], who studied 68 patients with HL and found that interim rPET2 value of 1.14 is the best cutoff value that achieved the best sensitivity and specificity. More detailed criteria about patients who showed bad prognosis during follow-up in spite of negative interim PET are summarized in Table 6. In our schema, a complete metabolic response (CMR) is defined as a return of FDG uptake in previously documented lesions to a level equivalent to, or less than, residual radioactivity in normal tissues within the organ in question. The interpretation of this study using DS showing a positive result score 4 as sternal activity is higher than that of liver, while rDS=1.22 which is less than the cutoff point (liver max 1.8). Cite this article. Bethesda, MD 20894, Web Policies PubMed The interpretation of early response evaluation PET (interim PET done after two cycles of CTH) is a subject of ongoing debate. 2014;99 (6): 1107-13. P value was set significant at 0.05 level. The positive group involved all cases with residual, stationary or progressive disease (DS4 and DS5), while the negative group involved all patients with complete metabolic regression and no residual active lesions (DS1 and DS2) [7]. To the left: Initial study shows metabolically active FDG-avid infiltrates involving both kidneys, bone marrow, and bone. On the contrary, Yao et al. government site. OM performed the statistical analysis of data. For comparing categorical data, chi-square (2) test was performed. Recently, a ratio between semiquantitative parameters (e.g., target lesion and liver SUV) has been proposed for interim FDG-PET/CT interpretation as it allows conversion of the visual qualitative scale to a continuous semiquantitative scale and permits evaluation of interim FDG-PET/CT through a well-determined semiquantitative-based cut-point [5]. A 4 or 5 Deauville score assessed by (18)F-FDG-PET CT early post-allotransplant is highly predictive of relapse in lymphoma patients . Diffuse large B-cell lymphoma, or DLBCL, is a cancer that starts in white blood cells called lymphocytes. Also, the 5p-DS and rPET were in agreement with most of the patients (87/89, 97.8%). Eur J Nucl Med Mol Imaging 41(7):13011308. The purpose of this study was to evaluate the prognostic role of the semiquantitative ratio Deauville score (rDS), defined as the ratio between target lesion and liver maximum standardized uptake values in children with FDG-avid extra-nodal lymphomas, undergoing interim FDG-PET/CT, and to compare it with the 5-point Deauville score (5p-DS). Scores of 1 and 2 are considered to be negative and 4 and 5 are considered to be positive. . Careers. Moderately increased uptake compared to the liver, Lymphoma in children and young people. The images or other third party material in this article are included in the article's Creative Commons licence, unless indicated otherwise in a credit line to the material. 1. This prospective study included 89 children with FDG-avid extra-nodal lymphoma. Normal lymphatic tissue may display low to moderate FDG uptake in the head and neck region. The uptake value is represented by pixel or voxel intensity value in the ROI of the image, which is then converted into the activity concentration. The Lugano Classification uses the same scale as the Deauville score but refers to it as a 5 point score (5PS). VOI is identified and drawn, for each lesion either nodal or extra-nodal lesion automatically for generating 3D iso-count contours using a fixed threshold of 40% of the SUVmax (V40%). You will then have dacarbazine as a drip over at least 30 minutes. Deauville score versus ratio Deauville score in the interpretation of interim 18F-FDG PET-CT and in prediction of outcome in children with FDG-avid extra-nodal lymphomas, https://doi.org/10.1186/s43055-022-00899-6, Egyptian Journal of Radiology and Nuclear Medicine, https://doi.org/10.1007/s00259-014-2973-6, https://doi.org/10.1007/s00259-014-2715-9, https://doi.org/10.1007/s00259-012-2280-z, https://doi.org/10.1080/10428190903040048, https://doi.org/10.1371/journal.pone.0211649, https://doi.org/10.21147/j.issn.1000-9604.2017.01.07, http://creativecommons.org/licenses/by/4.0/. 2022 Feb 10;139(6):822-834. doi: 10.1182/blood.2021013998. This ratio has some important technical and practical advantages over visual analysis as it is independent of the amount of administered activity and body weight; it also allows conversion of a visual qualitative scale (as 5p-DS) in a continuous semiquantitative scale through a well-determined semiquantitative-based cut-point [8, 9]. Google Scholar, Fan Y-G, Zhang Y, Yang Z, Ying Z, Zhou N, Liu C, Song Y-Q, Zhu J, Wang X-J (2017) Evaluating early interim fluorine-18 fluorodeoxyglucose positron emission tomography/computed tomography with the SUVmax-liver-based interpretation for predicting the outcome in diffuse large B-cell lymphoma. ROC curve analysis of our selected cutoff value. For an rPET/rDS outcome of 1, that is, when the borderline equality target "SUVmax = liver SUVmax" is found in clinical practice, the corresponding metabolic uncertainty (MU) provides the upper and lower limits of the confidence interval around the outcome of 1 (CI; usually given with 95% reliability) where the "true rPET" value may range. The maximum standardized uptake value (SUVmax) is widely used for measuring the uptake of FDG by malignant tissue (Gambhir 2002). (Negative PET images are scored as 1 or 2 and positive PETs are scored as 3, 4 or 5, depending on the level of uptake.). Li YH, Zhao YM, Jiang YL, Tang S, Chen MT, Xiao ZZ, Fan W, Hu YY, Zhang X. Eur J Nucl Med Mol Imaging. The predictive role of interim positron emission tomography for Hodgkin lymphoma treatment outcome is confirmed using the interpretation criteria of the Deauville five-point scale. It takes advantage of two reference points of the individual patient,which have demonstrated relatively constant uptake on serial imaging. Med. Epub 2020 Jul 4. Egyptian Journal of Radiology and Nuclear Medicine The receiver operating characteristic (ROC) approach was applied to identify the optimal cut-point of rPET with respect to events, to calculate accuracy values and to define the area under the curve (AUC). Eur J Nucl Med Mol Imaging 44:16021603, Toledano MN, Vera P, Tilly H, Jardin F, Becker S (2019) Comparison of therapeutic evaluation criteria in FDG-PET/CT in patients with diffuse large-cell B-cell lymphoma: prognostic impact of tumor/liver ratio. (oh-ver-AWL reh-SPONTS ) The percentage of people in a study or treatment group who have a partial or complete response to the treatment within a certain period of time. Progression-free survival curves for DS interim negative and positive groups. After a median follow-up time of 37.2 months, the recurrence-free survival rate (86.6% vs. 66.8%, P = 0.041) and overall survival rate (86.9% vs. 62.2%, P = 0.009) at 5 years were significantly different between the DS 1-3 and DS 4-5 arms. Consequently, the rPET cut-point of 1.25 seems to be accurate to identify patients with aggressive disease. As previously mentioned, the signs and symptoms of MCL are dependent on the extent of the region of the body that is affected. PET/CT imaging was performed before and after 4 courses of chemotherapy.The optimum cutoff values of SUVmax .

Springer Nature. The SUV of this nodule in the right upper lobe is 4.0. California Privacy Statement, Lymphoma . Shown are the criteria for interpretation of interim FDG-PET/CT. Early evaluation of disease response to chemotherapy (CTH), using 18F- FDG PET, was found to be a surrogate marker of therapeutic outcome, and it has been found to be a useful tool for predicting prognosis and risk stratification of lymphoma patients that consequently has a crucial role in management of such cases. . [10] showed that patients with rPET>1.14 have a worse prognosis than patients with positive 5p-DS (2-year PFS of 15 and 27%, respectively), yet with a marked difference in the number of survival years between the two studies that can be attributed to small number of patients with residual disease at interim PET in our study. 8600 Rockville Pike 2013;2012: 397-401. The brighter the nodule appears on the PET scan, the more likely that it is cancer. Fluorine-18 is one of the several isotopes of fluorine that is routinely used in radiolabeling of biomolecules for PET; because of its positron emitting property and favorable half-life of 109.8 min. Role of Imaging in the Staging and Response Assessment of Lymphoma: Consensus of the International Conference on Malignant Lymphomas Imaging Working Group.
