摘要心脑血管疾病是我国因病致死的首要死因,其发病率逐年上升.CT血管成像(CTA)检查心脑血管疾病逐渐广泛应用于临床,它能够全方位地观察心脑血管,清晰显示血管的解剖结构及病变部位.传统的心脑血管扫描分为两次,辐射剂量大且操作复杂.近年来,许多学者对心脑血管联合扫描一站式成像进行了研究,其简便、快捷、无创、辐射剂量低、对比剂使用少、准确性高等优点使其被广泛应用.笔者就CTA在心脑血管一站式成像中的研究进展进行综述.

abstractsCardiovascular and cerebrovascular diseases are the leading cause of death in China,and the incidence is increasing annually.CT angiography (CTA) examination of cardiovascular and cerebrovascular diseases is gradually extensively used in clinical practice.CTA can observe cardiovascular and cerebrovascular diseases in all directions and clearly shows the anatomical structures and lesions of blood vessels.The traditional cardio-cerebrovascular system is divided into two scans with large radiation dose and complicated operation.Many scholars have studied the simultaneous scanning of cardiac and cerebral vessels with one-step stop imaging in recent years.This method is widely promoted given its advantages,that is,simplicity,fast,noninvasive,low radiation dose,minimal contrast medium,and high accuracy.The author reviewed the research progress of CTA in cardiac and cerebral vascular one-step stop imaging.
