We evaluated the feasibility of angiographic CT (ACT) for visualizing metallic stents in three patients who underwent intracranial (n = 2) or extracranial (n = 1) stent placement to treat atherosclerotic lesions. ACT is a new technique that provides cross-sectional CT-like images based on rotational radiography performed with a rotating C-arm-mounted flat-panel detector. ACT allowed for the clear visualization of stents in both intracranial and extracranial arteries and was superior to conventional digital subtraction angiography and digital radiography in visualizing both the stent struts and their relationships to the arterial walls and aneurysmal lumen.
我们评估了血管造影CT（ACT）在三名接受颅内（n = 2）或颅外（n = 1）支架置入术以治疗动脉粥样硬化病变患者中可视化金属支架的可行性。ACT是一种新技术，它基于使用安装在旋转C形臂上的平板探测器进行的旋转射线照相提供类似CT的横断面图像。ACT能够清晰地显示颅内和颅外动脉中的支架，在显示支架支柱及其与动脉壁和动脉瘤腔的关系方面优于传统数字减影血管造影和数字射线照相。
