Fig. 3 —54-year-old woman with suspected coronary artery disease.
Image shows blurring due to motion caused by premature atrial contraction. At
short R-R interval, rest phase was too short for motion-free imaging of
coronary artery segment that presumably had large motion range at this time,
causing blurring. This segment of right coronary artery is frequently affected
by motion artifacts. Mean heart rate was 66 beats per minute. R-R interval
during acquisition varied between 641 and 1,194 milliseconds.
