Recent advances in angiography equipment have allowed the development of rotational digital subtraction carotid angiography. We give the first description of this technique applied to the extracranial carotid circulation, using the Phillips Integris V3000 release 11. Forty-three patients undergoing conventional digital subtraction angiography were compared with 63 patients who had rotational digital subtraction angiography for examination of the extracranial carotid circulation. The parameters compared were: total procedure time, volume of contrast injection, number of contrast injections, total data acquisition time, image quality, radiation dose and patient comfort. There was a reduction in the total procedure time, improvement in patient comfort, data acquisition time and a reduction in the number of injections. Conventional DSA may underestimate stenoses in 65% of cases. There is no significant change in the total volume of contrast injected. There is, however, an increase in the radiation dose during data acquisition.
血管造影设备的最新进展推动了旋转数字减影颈动脉血管造影技术的发展。我们首次描述了使用飞利浦Integris V3000第11版软件将该技术应用于颅外颈动脉循环的情况。将43例行传统数字减影血管造影的患者与63例行旋转数字减影血管造影以检查颅外颈动脉循环的患者进行比较。比较的参数包括：总操作时间、造影剂注射量、造影剂注射次数、总数据采集时间、图像质量、辐射剂量和患者舒适度。结果显示总操作时间缩短，患者舒适度、数据采集时间得到改善，注射次数减少。传统数字减影血管造影在65%的病例中可能低估狭窄程度。造影剂注射总量无显著变化。然而，数据采集期间辐射剂量增加。
