In this work, the feasibility is explored for subtractionless
first-pass time-resolved contrast enhanced MRA of the lower legs on 1.5T using Dixon, viewsharing
and parallel imaging with high acceleration factors. Results in seven consecutive
patients are analyzed and compared with the conventional subtraction method. It is demonstrated that with the subtractionless
method, bulk motion artifacts are eliminated, and SNR is significantly increased.
