Fig. 4 — Case example of the patient in Fig. 2. Curved planar reformation (CPR) images in the proximal section of the left anterior descending artery (LAD) with SR-DLR (a) and MBIR (b). Two cross-sectional images show the proximal reference site (c and d) and the site of maximal stenosis (e and f) correspond to red dashed lines on the CPR image. Coronary lumen and plaque (white arrows) were more sharply delineated on SR-DLR (c, e) than those on MBIR (d, f). CPR, curved planar reformation; LAD, left anterior descending artery; SR-DLR, super-resolution deep learning reconstruction; MBIR, model-based iterative reconstruction
