Re: value of power Doppler and gray-scale US in the diagnosis of carpal tunnel syndrome: contribution of cross-sectional area just before the tunnel inlet as compared with the cross-sectional area at the tunnel.

摘要

Dear Editor:I recently read your published article entitled "Value of Power Ooppler and Gray-Scale US in the Diagnosis of Carpal Tunnel Syndrome: Contribution of Cross-Sectional Area just before the Tunnel Inlet as Compared with the Cross-Sectional Area at the Tunnel" with interest. Dr. Akcar's article is very informative in that it described the axial images of the median nerve at three levels: just proximal to the tunnel inlet, at the level of the pisiform bone, and at the level of the hamate bone. Measurements of the cross-sectional area of the median nerves at the different levels have been used as indicators in the diagnosis of carpal tunnel syndrome. Another diagnostic indicator is the increased cross-sectional area at the level of the pisiform bone compared to the level of the distal radius.
