Numerous reports in the literature indicate that various noninvasive vascular techniques can now be used to evaluate atherosclerosis at the carotid bifurcation. This article reviews noninvasive screening techniques currently available and being developed. Particular emphasis has been placed on the practicality of these techniques as well as their limitations. Our conclusions are that noninvasive techniques cannot be used as definitive screening tests for cerebrovascular disease. Although these tests are frequently useful when positive, the false negative rate of these tests would appear to be significant and variable in different hands. Nonstenotic ulcers are usually not detected and total occlusion often not differentiated from stenosis. These tests should be viewed as the beginning rather than the end result of a developing field. At present, contrast arteriography remains the definitive test to evaluate the presence and significance of extracranial cerebrovascular disease.
文献中的大量报告表明，现在各种非侵入性血管技术可用于评估颈动脉分叉处的动脉粥样硬化。本文综述了目前可用及正在研发的非侵入性筛查技术。特别强调了这些技术的实用性及其局限性。我们的结论是，非侵入性技术不能用作脑血管疾病的确定性筛查试验。尽管这些试验呈阳性时通常很有用，但这些试验的假阴性率在不同人手中似乎很高且存在差异。非狭窄性溃疡通常无法检测到，完全闭塞也常常难以与狭窄区分开来。这些试验应被视为一个发展领域的起点而非最终结果。目前，血管造影仍是评估颅外脑血管疾病的存在及其意义的确定性检查。
