FIGURE 6. (A) 3-Dimensional volume-rendered image of patient showing status after left internal mammary graft to middle segment of left anterior descending coronary artery (arrowheads). Operative clips are visualized parallel to course of graft. In addition, venous coronary bypass graft can be seen between aorta and left circumflex coronary artery (arrows). (B) Curved MPR image with sharp image filter reconstruction of right coronary artery in patient with percutaneous stent placement (arrowhead). Lumen of stent (3.5-mm diameter) is patent. There is no evidence of in-stent restenosis or neointimal hyperplasia. In addition, this patient has large noncalcified plaque that protrudes into lumen of proximal right coronary artery, causing significant stenosis (arrow).
