WebMRI of Bone Marrow Changes Solution to Question 1 MRI is helpful for characterizing marrow abnormalities. A combination of characteristics seen on different imaging sequences can favor neoplastic or nonneoplastic changes. Fluid-sensitive sequences, including inversion recovery and T2-weighted fat-suppressed sequences, can accentuate ar-
