Recent advances in magnetic resonance imaging of musculoskeletal tumours.
Magnetic resonance imaging (MRI) has become the method of choice, where available, for the evaluation of musculoskeletal neoplasms. Recently, there has been interest and development in a number of areas in this field: (a) gradient-echo (fast-scan) sequences, which may often be substituted for more time-consuming T2-weighted sequences, are useful as localizing sequences and play an important role in intravenous contrast-enhanced scanning; (b) magnetic resonance contrast agents (e.g., gadolinium) improve delineation of tumours on static imaging and may help in estimating tumour aggressiveness with dynamic imaging; (c) STIR (short inversion time inversion recovery) increases lesion conspicuity; (d) spectroscopy, still an investigational area, may help in evaluating tumour response to chemotherapy and radiotherapy.
