The diffusion WB-MRI allows for detailed visualization of BM lesions and surrounding soft tissues both in the debut of the FL and in the process of tracking the effectiveness of chemotherapy, which makes it possible to use it along with PET/CT. Diffusion WB-MRI allows to separately evaluate the volume of true tumor tissue and residual tissue. Cases of the 3 grade of FL (including the transformation of FL into diffuse B-large cell lymphoma) are isolated due to low DC values (and high SUV values) in the tumor tissue. BM foci of FL lesion also have (in comparison with nodal and extranodal foci) lower DC values. The predictors of a poor antitumor response were high (from 14.0 or more) SUV valuesin the tumor (and especially in bulky), and low (about 0.5103mm2/s) DC values of BM foci. The PET/CT and diffusion WB-MRI have proven to be reliable diagnostic tools for establishing the stage of FL and detecting BM damage. Diffusion WB-MRI for FL is an informative first-line diagnostic method that allows regular monitoring of the disease and early detection of foci of relapse and disease progression.
