Current advances in CT techniques allow thorough evaluation of the beating heart. The strengths of cardiac CT relative to echocardiography and magnetic resonance imaging are its high availability in most institutions, rapid production of high-quality images, and outstanding delineation of the anatomy. For many normal variants and pathologic conditions, such as thrombi, masses, and congenital abnormalities of the left atrium, CT findings are sufficient to make a presumptive diagnosis. Assessments of the left atrium and left atrial appendage are particularly important for the management of atrial fibrillation, as various catheter-based procedures are aimed at the mechanical and electrical isolation of these structures. CT offers information crucial to a successful catheter-based procedure or surgery. Therefore, a comprehensive review of the geometry (shape, size, and relative position), along with various CT imaging features of pathologic states, should be provided in radiology reports to be of clinical value.
CT技术的当前进展使得能够对跳动的心脏进行全面评估。心脏CT相对于超声心动图和磁共振成像的优势在于，它在大多数机构中都很容易获得，能够快速生成高质量图像，并且对解剖结构的描绘非常出色。对于许多正常变异和病理状况，如血栓、肿块以及左心房先天性异常，CT检查结果足以做出初步诊断。对左心房和左心耳的评估对于房颤的治疗尤为重要，因为各种基于导管的手术旨在对这些结构进行机械和电隔离。CT提供了对于成功实施基于导管的手术或外科手术至关重要的信息。因此，放射学报告中应提供对几何结构（形状、大小和相对位置）以及病理状态的各种CT成像特征的全面综述，以便具有临床价值。
