Background. The purpose of this study was to compare the accuracy of whole-body MRI with diffusion-weighted sequences (WB-DW-MRI) with that of @entity419 -PET/CT in the staging of @entity1 with primary @entity344 . Methods. This retrospective study involved 17 untreated @entity1 with primary @entity344 . All @entity1 underwent @entity419 -PET/CT and WB-DW-MRI. Histopathology findings or at least 6 months of clinical and radiological follow-up was the gold standard. The Musshoff-modified Ann Arbor system was used for staging, and diagnostic accuracy was evaluated on a per-node basis. Results. WB-DW-MRI exhibited 100% sensitivity, 96.3% specificity, and 96.1% and 100% positive and negative predictive values ( @entity2286 and NPV), respectively. The sensitivity, specificity, and @entity2286 and NPV of PET/CT were 95.9%, 100%, and 100% and 96.4%, respectively. There were no statistically significant differences between the two techniques (p = 0.05). The weighted kappa agreement statistics with a 95% confidence interval were 0.97 (0.95-0.99) between the two MRI readers and 0.87 (0.82-0.92) between the two methods. Conclusions. WB-DW-MRI appears to have a comparable diagnostic value to @entity419 -PET/CT in staging @entity1 with @entity344 .
