Diagnostic Performance of Quantitative Flow Ratio (QFR) Values Generated from Automatic TIMI Frame-Counting

2022-03-11

Abstract excerpt

<h4>Background: </h4> QFR (quantitative flow ratio) is a computational measurement of FFR (fractional flow reserve), calculated from coronary angiography. Latest QFR software automates TIMI frame counting (TFC), which occurs during the flow step of QFR analyses, making the analysis faster and more reproducible. The objective is to determine the diagnostic performance of QFR values obtained from analyses using auto...
