摘要
冠状动脉CT血管造影(CCTA)广泛应用于冠状动脉疾病的诊断,但CCTA只能提供冠状动脉的解剖学信息,在分析冠状动脉功能性狭窄方面存在不足。随着CCTA一些新技术的发展,使得CCTA可同时提供冠状动脉的解剖学和功能学信息。本文对CCTA的管腔内衰减梯度(TAG)进行综述。
Coronary CT angiography (CCTA) was widely used in the diagnosis of coronary artery disease, however, CCTA could only provide anatomic information of the coronary artery. Along with the development of some new technolo gies of CCTA, CCTA could provide both anatomical and functional information of coronary artery. The transluminal atten uation gradient (TAG) in CCTA was reviewed in this article.
