MSK protocol

Long Bones MRI

MRI of the long bones (humerus, forearm, femur, tibia/fibula, thigh, calf) for marrow abnormalities, neoplasm, infection, cartilaginous defects, fractures, and soft tissue masses. Coronal STIR and T1 provide bone-length coverage; axial sequences provide cross-sectional characterization of the area of interest.
