Different concepts of combined clinical and interventional MR imaging expanded the spectrum of musculoskeletal interventional MR imaging into clinically useful procedures in children and adults. In this exhibit, we review the pertinent principles, indications, advantages, and drawbacks of interventional MR imaging relevant to musculoskeletal procedures. Minimally invasive, MR-guided techniques of percutaneous procedures are taught through illustrative case examples, including diagnostic osseous biopsy, therapeutic osseous interventions such as drill-assisted resection, soft tissue biopsy, preoperative percutaneous tumor marking, and injection procedures including selective nerve injections, epidural injections, facet joint injections, sacroiliac joint injections, discography, sympathetic blocks, and temporomandibular joint injections.
