Intravascular ultrasound (US) imaging is a new, evolving technique in which a high-frequency transducer is placed on the tip of a catheter. With this device it is possible to obtain high-resolution images of vessel structure in real time. This may provide valuable information about the degree of stenosis, as well as the type and extent of atherosclerotic plaque, in relation to the underlying tunica media and adventitia. The intravascular US catheter was used in seven patients undergoing transfemoral angiography because of arteriosclerosis obliterans. High-resolution images were obtained in all seven patients, and no complications were noted. Various US findings were demonstrated and correlated with the angiographic findings.
血管内超声（US）成像是一种新兴的技术，其中高频换能器置于导管尖端。使用该设备能够实时获取血管结构的高分辨率图像。这可以提供有关狭窄程度以及动脉粥样硬化斑块的类型和范围的有价值信息，这些信息与底层的中膜和外膜相关。血管内超声导管用于7例因动脉硬化闭塞症而接受经股动脉血管造影的患者。所有7例患者均获得了高分辨率图像，且未发现并发症。展示了各种超声检查结果并与血管造影结果进行了对比。
