Coronary artery aneurysm and perfusion defect in Kawasaki disease. A volume rendered reformat of a 3D whole heart bSSFP sequence with electrocardiogram (ECG) triggering, prospective respiratory navigator correction, flow insensitive T2-prepulse and a spectrally selective fat-saturation pulse was used to visualize the coronary artery lumen in a 3 year old patient with Kawasaki disease. A giant coronary artery aneurysm of the left main coronary artery (LMCA) was detected (A). The findings were confirmed by cardiac catheterization (B). Myocardial perfusion (balanced kt perfusion sequence, acceleration factor 5) was normal at rest (star in C). The suspicion of a left circumflex stenosis (arrows in A and B) was confirmed with adenosine stress perfusion (star in D)
