Previous reports of continuous-wave Doppler imaging have combined that technique with periorbital Doppler studies. In the present report, 75 patients with findings suggestive of cerebrovascular insufficiency were evaluated using continuous-wave Doppler imaging, oculopneumoplethysmography (OPG-G) and the cerebrovascular Doppler examination (CDE). Each test was interpreted independently. Doppler imaging had an overall accuracy of 85%, with a 68% accuracy in identifying 50-70% stenoses and a 69% accuracy in identifying high-grade stenoses (greater than 70%) and occlusion. OPG-G had an overall accuracy of 85%, with a 55% sensitivity for 50-70% stenoses and an 89% sensitivity for high-grade stenoses and occlusion. The CDE had an overall accuracy of 84% and a 50% sensitivity for stenoses of 50-70% and an 88% sensitivity for high-grade stenoses and occlusion. As an independent technique, continuous-wave Doppler imaging achieves an overall accuracy comparable to that of OPG-G or the CDE. Its sensitivity to high-grade stenosis and occlusion, however, is less than that of the other techniques. Since CDE and OPG-G had a 94% sensitivity to carotid occlusion and a combined sensitivity to high-grade stenoses and occlusion of 88% and 89%, respectively, their combined use with Doppler imaging offers sensitivity to and differentiation of stenoses from occlusion.
先前关于连续波多普勒成像的报告已将该技术与眶周多普勒研究相结合。在本报告中，对75例提示脑血管供血不足的患者进行了连续波多普勒成像、眼体积描记法（OPG-G）和脑血管多普勒检查（CDE）评估。每项检查均独立解读。多普勒成像的总体准确率为85%，识别50%-70%狭窄的准确率为68%，识别高度狭窄（大于70%）和闭塞的准确率为69%。OPG-G的总体准确率为85%，对50%-70%狭窄的敏感度为55%，对高度狭窄和闭塞的敏感度为89%。CDE的总体准确率为84%，对50%-70%狭窄的敏感度为50%，对高度狭窄和闭塞的敏感度为88%。作为一种独立技术，连续波多普勒成像的总体准确率与OPG-G或CDE相当。然而，其对高度狭窄和闭塞的敏感度低于其他技术。由于CDE和OPG-G对颈动脉闭塞的敏感度为94%，对高度狭窄和闭塞的联合敏感度分别为88%和89%，将它们与多普勒成像联合使用可提高对狭窄的敏感度并区分狭窄与闭塞。
