Abstract

To determine the predictive accuracy of Doppler and real-time ultrasound studies, continuous-wave Doppler (CWD) and B-mode real-time ultrasound (RTU) studies of the carotid bifurcation were compared in 50 consecutive patients before cervicocranial arteriography. Four categories of CWD results were formed according to the severity of stenosis. Except for mild to moderate stenosis, there was a high degree of agreement (87.5% to 98.1%) between CWD results and arteriographic diagnosis. Of the arteries classified as normal on RTU study, 95.5% were arteriographically normal; of those classified as abnormal, 94.9% were abnormal on arteriography. In 94.7% of the cases in which RTU demonstrated a possible ulcer, the diagnosis was confirmed by arteriography.

摘要

为确定多普勒超声和实时超声检查的预测准确性，在50例连续的患者行颈颅动脉造影前，对其颈动脉分叉处进行了连续波多普勒（CWD）和B型实时超声（RTU）检查，并对结果进行比较。根据狭窄程度将CWD结果分为四类。除轻度至中度狭窄外，CWD结果与动脉造影诊断之间具有高度一致性（87.5%至98.1%）。在RTU检查中分类为正常的动脉中，95.5%在动脉造影中为正常；在分类为异常的动脉中，94.9%在动脉造影中为异常。在RTU显示可能存在溃疡的病例中，94.7%经动脉造影确诊。
