From: Breath-hold imaging of the coronary arteries using Quiescent-Interval Slice-Selective (QISS) magnetic resonance angiography: pilot study at 1.5 Tesla and 3 Tesla

39-year-old male evaluated for chest pain. Left: 5-mm MIP of coronary CT angiography shows mild narrowing of the proximal LAD and a punctate coronary calcification (arrow). Middle: MIP of breath-hold radial QISS MRA obtained at 1.5 Tesla demonstrates the left main and LAD coronary arteries, including the D1 and D2 branches. The appearances are similar to the coronary CT angiogram except that the wall calcification is not visible. Right: MIP from navigator-gated 3D bSSFP also demonstrates the left coronary anatomy comparably to the coronary CTA. Compared with QISS, there is increased pericardial fluid signal (arrows)
