A unique method of computerized image enhancement makes it possible to visualize the arterial system by intravenous (IV) injection of small doses of standard contrast agent. This technique has been used to study the intracranial and extracranial circulation of more than 100 patients. Occlusion, stenosis, aneurysmal change, plaquing, and ulceration can be identified by computerized IV arteriography. Failures (less than 10%) results from inadequate venous access, extravasation of dye, or patient motion. This technique avoids the need for arteriography. The major risk of IV arteriography is contrast medium reaction. There is a close correlation between IV and standard arteriographic images. Intravenous arteriography does not require hospitalization, is suited for repetitive testing, and has promise as a method of diagnostic screening for stroke prevention.
一种独特的计算机图像增强方法使得通过静脉注射小剂量标准造影剂来可视化动脉系统成为可能。这项技术已被用于研究100多名患者的颅内和颅外循环。闭塞、狭窄、动脉瘤样改变、斑块形成和溃疡可通过计算机静脉血管造影识别。失败情况（少于10%）是由于静脉通路不足、染料外渗或患者移动所致。该技术避免了动脉造影的必要性。静脉血管造影的主要风险是造影剂反应。静脉血管造影图像与标准动脉造影图像密切相关。静脉血管造影不需要住院，适合重复检查，有望成为预防中风的诊断筛查方法。
