A comparison is made of the use of selective intra-arterial subtraction angiography and doppler sonography in the assessment of disease in 206 carotid arteries. Maximal stenoses in each of the internal, external and common carotid arteries were recorded and compared using both modalities. In 93% of cases, arteries reported as normal ultrasonically were also found to be normal on angiography. However, agreement between the modalities in the assessment of severe stenoses was rather less at 79%. Overall agreement between the two modalities was good using statistical analysis (weighted Kappa). It is our view that ultrasound is reliable in normal vessels, but where significant disease is present the rate of error between the two modalities is too high to warrant omission of angiography.
对206条颈动脉疾病评估中选择性动脉内减影血管造影和多普勒超声检查的使用情况进行了比较。记录了颈内动脉、颈外动脉和颈总动脉各自的最大狭窄程度，并使用这两种方法进行比较。在93%的病例中，超声报告为正常的动脉在血管造影中也被发现是正常的。然而，在评估严重狭窄时，两种方法之间的一致性较低，为79%。使用统计分析（加权Kappa），两种方法之间的总体一致性良好。我们认为，超声在正常血管中是可靠的，但在存在明显疾病的情况下，两种方法之间的误差率过高，不能保证省略血管造影。
