While self-navigated (SN) whole heart coronary MRA data have successfully been acquired in healthy adult subjects, the performance of this technique remains to be ascertained in patients with suspected or established coronary artery disease (CAD). In this work our 3D radial SN whole-heart technique was optionally integrated in clinical examinations of 60 patients with suspected or confirmed CAD. All coronary segments were graded by experts and compared with x-ray angiography, when available, for detection of stenoses. The SN technique was also tested for identification of congenital anomalies of the coronary arteries.
