Magnetic Resonance Imaging (MRI) and specific cytogenetic abnormalities offer important prognostic information for myeloma patients. However, limited data are available about the association between cytogenetic abnormalities and MRI patterns of marrow infiltration. To address this issue, we analyzed 228 consecutive newly diagnosed, symptomatic patients who were diagnosed and treated in a single center. On bone marrow MR images, 95 (41%) patients had diffuse, 94 (41%) had focal, 35 (15%) were normal, and 4 (1.7%) patients had variegated pattern of marrow infiltration. High risk cytogenetics were more commonly observed with diffuse MRI pattern (50% vs. 31% in focal and normal patterns). Patients with diffuse MRI pattern had poorer survival compared to others and responded better to novel agent‐based therapies than to conventional chemotherapy (objective response: 88% vs. 46%, P < 0.001 …
