Correlation Between Quantitative Analysis of Coronary MRA and FFR


Brief description of study

This study aims to evaluate whether quantitative analysis of coronary MR angiogram would improve the detection of functionally-significant coronary artery stenosis.

Detailed Study Description

Coronary MR angiography is performed with a 3.0-T imager with 32-channel coils. Qunatitative analysis of coronary MR angiogram is evaluated on the basis of the signal intensity (SI) profile along the vessel. Quantitative analysis of coronary MR angiogram (QCMRA) is calculated as [1 - (SImin/SIref)] x 100, where SImin is minimal SI and SIref is corresponding reference SI. Diagnostic performance of quantitative analysis of coronary MR angiogram for predicting functional significant coronary stenosis was evaluated by using fractional flow reserve (FFR) as the reference standard.
