Musculoskeletal Tumor Imaging for Staging and Treatment Planning

Overview

The prognosis of patients with musculoskeletal tumors has improved markedly because of the advent of new chemotherapeutic drugs and regimens and as a result of advances in imaging and surgical techniques. Limb-salvage operations can currently be performed with better outcomes, while in the past, limbs with tumors were treated only with amputation. Accurate preoperative surgical staging of musculoskeletal tumors is currently possible because imaging techniques provide prognostic information and aid clinicians in choosing the most appropriate treatment option for the patient.
