3 Tesla is the preferred field strength for perfusion imaging in coronary artery disease – a comparison to 1.5 Tesla and fractional flow reserve

چکیده
Background Adenosine perfusion imaging at 1.5 Tesla (T) has been shown to yield good diagnostic values in comparison to quantitative coronary angiography. Perfusion imaging at 3 T has the potential benefit of higher contrastand signalto-noise ratios. However, little is known about diagnostic performance of 3 T perfusion imaging in comparison to 1.5 T and in comparison to invasive measurement of fractional flow reserve (FFR). We sought to evaluate visual and quantitative assessment of adenosine perfusion at 3 T in comparison to 1.5 T and to coronary angiography in patients presenting with suspected coronary artery disease (CAD).

1.5 and 3 Tesla quantification of myocardial perfusion reserve in comparison to fractional flow reserve
Methods Thirty-four patients referred for coronary x-ray angiography with suspected or known coronary artery disease underwent cardiac magnetic resonance imaging (CMR) at 1.5 and 3 Tesla, and additionally FFR measurement in LAD, CX and RCA. MPR was calculated in 544 myocardial segments at both field strenghts. FFR was measured in 109 coronary arteries with a cut-off value of ≤0.8 for relevant s...

We demonstrate the feasibility of 3D myocardial perfusion CMR at 3 Tesla against fractional flow reserve (FFR) in 53 patients for the detection of flow-limiting coronary artery disease and show good agreement between the techniques. This technique shows excellent diagnostic sensitivity and specificity and may offer an alternative method of detecting ischaemia for the purpose of guiding revascul...

Stress perfusion cardiac magnetic resonance (CMR) has been proposed as an important gatekeeper for invasive coronary angiography (ICA) and percutaneous coronary interventions (PCI) in patients evaluated for possible coronary artery disease (CAD) (Fihn et al., 2012; Montalescot et al., 2013) [1], [2]. Several meta-analyses have evaluated the accuracy of stress perfusion CMR to diagnose CAD at th...
