PET/CT is routinely performed in evaluation of disease burden in patients with Non Hodgkin Lymphoma (NHL). MRI with diffusion weighted imaging (DWI) has shown promise. In this study we compared the accuracy of morphologic MRI including DWI and PET/MR in detection of nodal disease with PET/CT as a reference. Our results suggest that PET/MR outperformed DWI for assessment of nodal disease and had sensitivity similar to PET/CT. Furthermore there was excellent correlation in SUVmax as measured with PET/MR and PET/CT. Thus PET/MR may be a viable option to PET/CT in evaluation of patients with lymphoma.
