Qualitative and Quantitative MRI Techniques for the Evaluation of Musculoskeletal Neoplasms

Musculoskeletal neoplasms include tumors arising from bone, cartilage, muscles, tendons, nerves, and synovium. After initial screening radiographs, magnetic resonance (MR) imaging is the mainstay of management, and its role continues to increase in both pre- and post-operative evaluations. This article presents a review of the available qualitative and quantitative MR techniques for evaluating musculoskeletal neoplasms, including conventional and advanced imaging techniques such as diffusion-weighted and diffusion-tensor imaging, chemical shift and Dixon imaging, dynamic contrast-enhanced MRI, neurography, and spectroscopy. After reading the article, radiologists and oncologists will be able to apply these principles in their practices to benefit patients with musculoskeletal neoplasms.
