FFRCT采用常规CT冠脉造影图像(CTA),采用一定算法,从图像中一方面提取血管的解剖学形态信息,另一方面提取血管的生理学信息,将两方面信息相结合,可以建立起血管的流体动力学模型,从而能够在任意的冠脉上的任意位置计算FFR。 图片来源https://www.heartflow.com/heartflow-ffrct-analysis/ 大家如果有兴趣,可以点击下面的网页...

calculated with FFR as golden standard. Diagnostic efficiency for coronary artery ischemia by CCTA stenosis and FFR ct were compared using receiver operating characteristic (ROC) curve, Bland-Altman analysis and Spearman analysis. Results All of 27 vessels from 18 patients were eligible for analysis ...

This manuscriptreviews the technique of CTFFR and discusses some of the challenges of widespread clinical implementation through value chain analysis." As the leading cause of death amongst men and women throughout the developed world, coronary heart disease is an important and expensive health ...
Purpose of Review Non-invasive fractional flow reserve derived from CT coronary angiography (FFRCT) offers an amalgamation of both coronary anatomy and physiology. This review aims to provide a contemporary evaluation of the evidence for clinical use of FFRCT. The review article pays particular ...
coronary stenosis, improving the positive predictive value of CCTA. However, to determine the value of FFRct in routine clinical practice, a pragmatic randomised, controlled trial (RCT) is required. We will conduct an RCT...
