The authors compared ultrasonography with electrophysiology for the diagnosis of carpal tunnel syndrome (CTS) on 110 clinically affected wrists. An increased cross sectional area in the proximal carpal tunnel larger than 0.11 cm(2) in combination with compression signs on longitudinal scans proved to be highly predictive for CTS (sensitivity, 89.1%; specificity, 98.0%). Ultrasound was comparable to electrophysiology in the diagnosis of CTS, and in 35% of cases changes in morphology suggested a specific therapeutic strategy.
作者对110例临床确诊的腕管综合征（CTS）患者的手腕进行了超声检查与电生理检查对比。近端腕管横截面积增大超过0.11平方厘米，同时纵向扫描出现压迫征，这对CTS具有高度预测性（敏感性89.1%；特异性98.0%）。在CTS诊断方面，超声与电生理检查效果相当，且在35%的病例中，形态学变化提示了具体的治疗策略。
