To compare a compiled clinical routine cardiac magnetic resonance imaging (CMR) protocol performed at both 1.5-T and 3.0-T in patients with suspected coronary artery disease (CAD) undergoing coronary x-ray angiography.
CMR including adenosine perfusion and late gadolinium enhancement (LGE) at 1.5-T has been established for noninvasive detection of relevant CAD. However, little is known about the potential advantages of 3.0-T to detect CAD.
Fifty-two evaluable patients (62.3 ± 10.2 years) were included into the study. All patients were scanned at both 1.5-T and 3.0-T including adenosine stress and rest perfusion, and LGE imaging. CMR images were analyzed by two blinded readers in consensus. A significant CAD was diagnosed by quantitative coronary analysis.
This study showed that CMR at 3.0-T in a routine clinical setting is superior to 1.5-T in detection of significant CAD. 3.0-T might become the preferred CMR field strength for evaluation of CAD in clinical practice.
This study was partly funded by a research grant of Guerbet, France.
