Figure 3. — High-attenuating coronary CT angiography artefacts on long-axis curvilinear reformation images of the left anterior descending artery: (a) a 65-year-old male with history of multiple coronary stentings. Two stents are visible, with the proximal one being highly attenuating (arrow) and preventing lumen visualization, while the distal stent exhibits a better luminal visibility (arrowheads). (b) A 69-year-old male with diabetes mellitus. Extensive calcifications prevent luminal assessment (arrows).
