Magnetic resonance imaging in the a literature review.
To determine the indications for magnetic resonance imaging (MRI) in the evaluation of individuals with carpal tunnel syndrome (CTS). a critical review of the literature was undertaken. Among the studies reviewed, a lack of uniformity in MRI equipment and techniques, conflicting sensitivity and specificity of imaging criteria for median nerve compression, and a paucity of normative data were noted. Based on this review, we conclude that MRI is not a useful tool for large-scale population screening, and is unhelpful as a routine preoperative study MRI is useful for confirmed CTS with persistent postoperative findings and in cases m which anatomic anomalies are suspected preoperative!)'. The use of MRI for guiding treatment deosions in individuals with clinical signs and symptoms of CTS but with normal electrodiagnostic studies remains undetermined.
