Variants and congenital anomalies of the coronary arteries are usually asymptomatic, but may present with severe chest pain or cardiac arrest. The introduction of multidetector CT coronary angiography (MDCT-CA) allows the detection of significant coronary artery stenosis. Improved performance with isotropic spatial resolution and higher temporal resolution provides a valid alternative to conventional coronary angiography (CCA) in many patients. MDCT-CA is now considered the ideal tool for three-dimensional visualization of the complex and tortuous anatomy of the coronary arteries. With multiplanar and volume-rendered reconstructions, MDCT-CA may even outperform CCA in determining the relative position of vessels, thus providing a better view of the coronary vascular anatomy. The purpose of this review is to describe the normal anatomy of the coronary arteries and their main variants based on MDCT-CA with appropriate reconstructions.
冠状动脉的变体和先天畸形通常是无症状的，但可能会出现严重胸痛或心脏骤停。多排螺旋 CT 冠状动脉造影（MDCT-CA）的引入可以检测到明显的冠状动脉狭窄。随着各向同性空间分辨率和更高时间分辨率的提高，MDCT-CA 在许多患者中成为常规冠状动脉造影（CCA）的有效替代方法。MDCT-CA 现在被认为是三维可视化冠状动脉复杂和迂曲解剖结构的理想工具。通过多平面和容积再现重建，MDCT-CA 在确定血管的相对位置方面甚至可能优于 CCA，从而提供更好的冠状动脉血管解剖视图。本文旨在描述基于 MDCT-CA 及其适当重建的冠状动脉的正常解剖结构及其主要变体。
