Magnetic resonance imaging of tendons

MRI provides unprecedented spatial resolution and contrast resolution of the soft tissues of the joints, allowing accurate evaluation of both normal anatomy and pathology of virtually any tendon. However, its exact role for the evaluation of tendon lesions is yet to be determined. In most instances, less expensive techniques like US, CT, or tenography can demonstrate the abnormality and provide enough information for patient management. MRI may be indicated in the following circumstances: to study suspected tendon lesions not demonstrated by other techniques, to evaluate tendons located in areas beyond the reach of US, or to study those cases in which the exact etiology of the symptoms is not clear on clinical grounds and lesions other than tendinous in origin may be present.
