We developed a new technique using hand-operated table movement during digital angiography (DA) for the study of vascular disease of the pelvis and lower extremities. Digital video memory (DVM) is used in this technique to digitize, record, and display fluorographic images without subtraction in real time. This allows free table movement and the imaging of a large area with a single injection of contrast medium. Forty-five examinations for vascular disease of the pelvis and lower extremities were performed by this DA technique. Good images of an extensive area from the lower abdomen to the lower leg were obtained in a single study.
我们开发了一种新技术，在数字血管造影（DA）期间使用手动移动检查台来研究骨盆和下肢的血管疾病。该技术使用数字视频存储器（DVM）实时数字化、记录和显示未经过减影处理的荧光图像。这允许检查台自由移动，并且通过单次注射造影剂就能对大面积区域进行成像。通过这种DA技术对45例骨盆和下肢血管疾病进行了检查。在单次检查中就获得了从下腹部到小腿的大面积区域的清晰图像。
