The aim of this study was to determine the impact of parallel acquisition on the imaging of coronary plaque under conditions of physiological motion and reduced FOV (inner volume) imaging. Our results indicate that parallel acquisition can improve the resolution of coronary plaque morphology due to a reduction in motion sensitivity. However, the high degree of overlap among coil element profiles in a small FOV focused on the coronary arteries dramatically reduces the potential benefits of using multi-channel receive coils in low SNR scenarios
