Percutaneous transluminal coronary angioplasty (PTCA) often is supplemented by the insertion of stents to prevent closing of the coronary arteries. This article reviews types of coronary stents and discusses the role that diagnostic imaging plays in their correct placement and determining their patency following implantation. The four primary diagnostic techniques used to image coronary stents--angiography, ultrasound, computed tomography and angioscopy--are discussed, along with the advantages and limitations of each.
经皮腔内冠状动脉成形术（PTCA）通常会辅以支架植入以防止冠状动脉闭塞。本文回顾了冠状动脉支架的类型，并讨论了诊断成像在其正确放置及植入后确定其通畅性方面所起的作用。文中讨论了用于冠状动脉支架成像的四种主要诊断技术——血管造影、超声、计算机断层扫描和血管镜检查——以及每种技术的优缺点。
