Ultrasonic echoarteriography is a noninvasive method of visualizing extracranial arteries in health and disease. The real-time echoscanning device developed at the University of Cincinnatti utilizes a 5-MHz (center frequency) pulse-echoimaging system. B-mode pictures of the tissues studied are obtained and displayed on a video screen, real-time operation being provided by the scanning mechanism operating at 30 frames per second. In our experiments internal arterial damage produced by surgically scraping the intima induced experimental thrombosis in nine carotid in nine carotid and three femoral arteries in dogs. Where pathologically demonstrated, the thrombi were demonstrated by ultrasonic echoarteriography in every instance. Echoarteriography seemed more sensitive than contrast arteriography in the detection of a partially occlusive thrombus.
超声回声动脉造影术是一种用于观察健康和患病状态下颅外动脉的非侵入性方法。辛辛那提大学研发的实时超声扫描设备采用了一个5兆赫兹（中心频率）的脉冲回波成像系统。所研究组织的B型图像被获取并显示在视频屏幕上，每秒30帧的扫描机制提供实时操作。在我们的实验中，通过手术刮擦内膜造成的动脉内部损伤在九条犬的颈动脉和三条股动脉中诱发了实验性血栓形成。在病理证实的情况下，每次都能通过超声回声动脉造影术显示出血栓。在检测部分闭塞性血栓方面，回声动脉造影术似乎比对比动脉造影术更敏感。
