The role of MR imaging in the evaluation of musculoskeletal tumors continues to evolve as new techniques emerge. While conventional T1 and fluid-sensitive sequences are entirely sufficient to determine the location and extent of a lesion, quantitative methodologies (chemical shift imaging, perfusion imaging, DWI, MR spectroscopy) have become available and provide metrics that may advance the role of MR imaging for characterization. Tumor extent is well-evaluated on anatomic pulse sequences, but with the advent of whole body imaging, the roles of MR imaging now include detection.
