Proposed method combines sensitivity encoding and undersampled projection reconstruction trajectory to greatly accelerate whole-heart coronary MRA. No separate calibration scans are needed since the densely sampled k-space central region allows direct sensitivity map extraction from image data. Results show that the proposed method reduces aliasing, hence allows a shorter scan time by acquiring less k-space samples, while minimizing the reduction in image quality.
