Figure 14a. Image blurring due to data shortage. A 60-year-old man underwent coronary CT angiography at standard pitch, during which his heart rate was 48 bpm. (a) Contiguous sections obtained at the level of the LAD and left circumflex arteries show blurring (arrowheads at left) in the left coronary artery as well as in the ascending aorta, pulmonary artery, right ventricle, and left atrium. Note that the images on the right show no motion artifacts. (b) Thin-slab MIP image shows pseudostenosis (arrow) and blurring (arrowheads) of the RCA. (c) Coronary catheter angiogram helps confirm the findings in b.
