A picture can say a thousand words and, in this case, it is all too true; understanding tumour metabolism, bone marrow involvement and disease progression can all be captured through imaging techniques. At the 1st European Myeloma Network (EMN) Meeting, held in Turin, Italy, Elena Zamagni, MD, PhD, from the University of Bologna, Bologna, Italy, talks about the role of PET-CT and MRI in analyzing measurable residual disease (MRD) in multiple myeloma (MM). Dr Zamagni notes the questions raised on the standardization and incorporation of MRD measurement within clinical trials, and how these will be improved with further research and time.
