Dual-source CT coronary angiography in a 69-year-old man with suspected coronary artery disease (mean heart rate during scanning 77 bpm, Agatston score 1,316). a Curved-planar reconstruction of the right coronary artery demonstrates high-grade coronary artery stenosis of the proximal segment (arrow) and non-significant stenoses of the mid and distal segments (arrowheads). b Invasive coronary angiography in a left anterior oblique projection (45°) confirms significant stenosis of the proximal segment of the right coronary artery (arrow) and non-significant stenoses of the mid and distal segments (arrowheads)
