Comparison Between Whole Body DWI and FDG PET/CT in Patients with Simptomatic Multiple Myeloma

The primary objective is to evaluate the concordance of FDG PET/CT and total body DWI MRI sequences performed during staging and at the completion of therapy. Specifically, we will assess the positivity rates, both patient-based and lesion-based (total and by district), of the two methods during staging and at the completion of therapy. An interim analysis will be conducted comparing the two methods, followed by a final prognostic analysis.
