Image quality and diagnostic accuracy of inline motion-corrected (moco) first-pass stress myocardial perfusion images

MOCO, a non-rigid image registration algorithm, can minimize myocardial motion and shape changes caused by respiration, arrhythmia, or imperfect gating. A potential benefit of this technique is to enable automated quantitative analysis. On the other hand, MOCO could introduce artifacts and adversely impact diagnostic image quality.
