Fig. 4

Evaluation of left anterior descending coronary artery of a single patient with both IR (a and c) and MBIR (b and d) reconstruction algorithm. The MBIR reconstruction better depicts the artery wall and the lesions in comparison with IR images because of lower image noise. a–b Curved reconstruction of the LAD artery showing multiple mixed atherosclerotic plaques in the proximal and intermediate tract. New model-based iterative reconstruction (MBIR) is also possible to evaluate the distal tract of the coronary artery analyzed. c–d Straight reconstructions of IR (c) and MBIR (d) images for a better evaluation of proximal atherosclerotic plaque, which determined luminal stenosis of 65–70% described as CAD-RADS 3
