Coronary magnetic resonance angiography (MRA) is emerging as a valuable non invasive tool for the evaluation of coronary artery disease (CAD). However, to achieve maximum accuracy in detection of CAD, contemporary MRI methods may benefit from a higher spatial resolution to approach that of the current gold standard x-ray coronary angiography (0.15mm). To date the commonly used in-plane spatial resolution at 1.5T and using gradient echo sequences is ~0.713mm3. This study demonstrates the feasibility of acquiring coronary MRA with a voxel size of 0.340.351.5mm3 on a commercial 3T scanner.
