The standard technique for CT investigation of the carpal tunnel and its normal anatomy were studied. Ten healthy asymptomatic volunteers, age 25-45, underwent wrist CT. The hand is placed in prone position with the third metacarpus in line with the radius. Digital radiograph and four axial CT scans are performed respectively: at the distal end of the radius, at the scaphoid tubercle level, at the hamate hook level and at the carpal-metacarpal joint. Standard carpal tunnel diameters are thus available with good reliability and repeatability when correct technique is adopted. The results permit a morphological description of the osseous walls, transverse ligament, flexor tendons with synovial sheets and median nerve. Gujon's canal and its content can also be investigated.
研究了腕管CT检查的标准技术及其正常解剖结构。10名年龄在25 - 45岁之间的健康无症状志愿者接受了腕部CT检查。手呈俯卧位，第三掌骨与桡骨对齐。分别进行数字X线摄影和四次轴向CT扫描：在桡骨远端、舟骨结节水平、钩骨钩水平和腕掌关节处。因此，采用正确技术时，标准腕管直径具有良好的可靠性和可重复性。这些结果有助于对骨性壁、横韧带、带滑膜鞘的屈肌腱和正中神经进行形态学描述。还可以研究古琼管及其内容物。
