Exertional dyspnea in a 69-year-old man. (a) Curved multiplanar reformatted CCTA image of the right coronary artery (RCA) shows scattered calcified and noncalcified plaque within the proximal and mid vessel. There is an area of moderate (50%–69%) stenosis (arrow), secondary to mixed calcified and noncalcified plaque within the mid RCA. (b) FFR CT image shows an FFR value of 0.86 distal to the moderate RCA stenosis, consistent with no functional significance of the mid RCA stenosis.
