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
