Magnetic resonance imaging (MRI) is now the modality of choice for the investigation of soft-tissue tumours, providing excellent anatomic detail and soft-tissue contrast. As the availability of MRI has increased, the number of requests for studies of the foot and ankle has similarly increased. The imaging department at the authors' institution, a tertiary care teaching hospital, has a large orthopedic and podiatric referral base, and as a consequence the authors have had the opportunity to study a large variety of benign soft-tissue tumours with MRI. In this pictorial essay they review the MRI and pathological appearances of the most common benign soft-tissue tumours that occur in the foot and ankle.

D008279	Magnetic Resonance Imaging	Non-invasive method of demonstrating internal anatomy based on the principle that atomic nuclei in a strong magnetic field absorb pulses of radiofrequency energy and emit them as radiowaves which can be reconstructed into computerized images. The concept includes proton spin tomographic techniques.
