Figure 9. — Coronary CT angiography in a 55-year-old male with history of left main trunk, left anterior descending and circumflex artery stenting: two different reconstructions algorithms (standard in a and sharper in b) are performed using iterative reconstruction techniques and the smallest field of view (8 cm). With the sharper reconstruction algorithm, higher image noise is seen as compared with the standard reconstruction, but more details of the proximal circumflex artery severe in-stent restenosis are seen (arrow in b), with a better correlation with catheter coronary angiography (arrow in c).
