Supplementary Figure 2 from Evaluation of Diffusion-Weighted MRI for Pretherapeutic Assessment and Staging of Lymphoma: Results of a Prospective Study in 140 Patients

PDF file - 455KB, A 56-year old male patient with histologically verified, infra-diaphragmatic SLL/CLL in the retroperitoneal/paraaortic lymph nodes (light blue arrows). These nodal lymphoma manifestations show a high signal (i.e., diffusion restriction) on DWI and the fused color-coded DWI-MRI images, and were thus rated as positive. On the other hand, they fail to show an elevated tracer uptake, relative to the surrounding tissues, on the 18F-FDG-PET and the fused color-coded PET/CT images, and were thus rated as negative. On CE-CT, the lymph nodes were rated as positive due to their abnormal long-axis diameter (>1.5 cm).
