Whole-body diffusion-weighted imaging compared with FDG-PET/CT in staging of lymphoma patients.

Background: Diffusion-weighted imaging (DWI) has become increasingly valuable in lymph node imaging, yet the clinical utility of this technique in the staging of lymphoma has not been established.

Purpose: To compare whole-body DWI with FDG-PET/CT in the staging of lymphoma patients.

Material And Methods: Thirty-one patients, eight with Hodgkin lymphoma (HL) and 23 with non-Hodgkin's lymphoma (18 aggressive and five indolent) underwent both whole-body DWI, whole-body MRI (T1W and T2W-STIR) and FDG-PET/CT.
