The role of ultrasonographic measurements of the median nerve in the diagnosis of carpal tunnel syndrome Full Text
Clinical Radiology, 12/13/2004
Increased cross-sectional area of the median nerve was the most predictive measurement of carpal tunnel syndrome. Using the ROC curve, a cut-off value of >10.5 mm2 at the level of pisiform bone provided a diagnostic sensitivity of 89% and specificity of 94.7%...Conclusion: The ultrasonographic measurement of the median nerve cross-sectional area is a sensitive, specific and useful non-invasive method for the diagnosis of carpal tunnel syndrome
