Following the introduction of endoscopy and newer imaging techniques, such as ultrasonography, computer tomography and magnetic resonance imaging, the indications for angiography have been reduced mainly to the diagnosis and treatment of unexplained gastrointestinal hemorrhage and ischemia. Radiologic signs of hemorrhage include extravasations of contrast medium, irregular vessels and aneurysms. Vascular stenoses and occlusions are the main radiologic signs of ischemia.
随着内窥镜检查以及超声、计算机断层扫描和磁共振成像等更新的成像技术的引入,血管造影的适应症已主要减少到不明原因的胃肠道出血和缺血的诊断与治疗。出血的放射学征象包括造影剂外渗、不规则血管和动脉瘤。血管狭窄和闭塞是缺血的主要放射学征象。
