In this project we compared a prototype non-contrast
free-breathing self-navigated 3D (SN3D) whole-heart MRA
acquisition and coronary CTA for the evaluation of the
proximal course of coronary arteries in a pediatric
patient population. Evaluation of image quality
according to a 4-grade scale (1, non-diagnostic; 2,
sufficient; 3, good; 4, excellent) and the visualization
of the left main, left anterior descending, circumflex,
first diagonal, posterior descending, and right coronary
arteries were performed, in both techniques, by two
experienced observers. Our preliminary results indicate
that the non-contrast free-breathing SN3D MRA
acquisition allows for the evaluation of coronary artery
anatomy with similar image quality to cCTA without any
radiation or administration of contrast agent.
