背景：本研究旨在评价基于冠状动脉CT血管造影（CTA）的定量血流比（quantitative flow ratio， QFR），即CT-QFR的诊断性能，并以血流储备分数（fractional flow reserve， FFR）为参考标准，与基于有创冠状动脉造影（ICA）的Murray law QFR （mu QFR）进行比较。方法：回顾性分析2个月内接受冠状动脉CTA、ICA和压力线FFR评估的患者。CT-QFR和mu QFR采用盲法计算，并与FFR进行比较，均采用相同的截止值
Background: The aim of this study was to evaluate the diagnostic performance of coronary CT angiography (CTA)-based quantitative flow ratio (QFR), namely CT-QFR, and compare it with invasive coronary angiography (ICA)-based Murray law QFR (mu QFR), using fractional flow reserve (FFR) as the reference standard.Methods: Patients who underwent coronary CTA, ICA and pressure wire-based FFR assessment within two months were retrospectively analyzed. CT-QFR and mu QFR were computed in blinded fashion and compared with FFR, all applying the same cut-off value of
