Noninvasive techniques are widely used to assess patients with cerebrovascular disease. The most common method is duplex ultrasonography, which has an accuracy of approximately 90% in the detection of carotid stenosis. There are many potential limitations to the technique of duplex ultrasonography, but in the hands of experienced technologists and physicians who recognize possible sources of error, it provides excellent clinical accuracy. Transcranial Doppler is complementary to duplex ultrasonography in the assessment of the intracranial circulation. Magnetic resonance angiography shows promise as a noninvasive method of assessing carotid stenosis, but its availability is limited, and this technique is still in the developmental stage.
非侵入性技术广泛用于评估脑血管疾病患者。最常用的方法是双功超声检查，其在检测颈动脉狭窄方面的准确率约为90%。双功超声检查技术存在许多潜在局限性，但在经验丰富的技术人员和认识到可能误差来源的医生手中，它能提供出色的临床准确性。经颅多普勒在评估颅内循环方面是双功超声检查的补充。磁共振血管造影作为评估颈动脉狭窄的一种非侵入性方法显示出前景，但其可用性有限，且该技术仍处于发展阶段。
