1 Accuracy of 64-Slice Multidetector Computed Tomography for Diseased Coronary Artery Graft Detection 
Masato Tochii, MD, PhD, Yasushi Takagi, MD, PhD, Hirofumi Anno, MD, PhD, Ryo Hoshino, MD, PhD, Kiyotoshi Akita, MD, Hiroshi Kondo, MD, Motomi Ando, MD, PhD  The Annals of Thoracic Surgery  Volume 89, Issue 6, Pages (June 2010) DOI: /j.athoracsur Copyright © 2010 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 Example of 47-year-old male case in coronary artery bypass grafting with right IMA to left anterior descending artery, and left IMA to obtuse marginal branch. Three-dimensional volume rendering image with 64-MDCT demonstrated accurate diagnosis. (64-MDCT = 64-slice multidetector computed tomography; IMA = internal mammary artery.)

3 Fig 2 A 65-year-old male underwent coronary artery bypass grafting. (A) The right IMA graft to left anterior descending artery was patent but showed string sign by selective catheter angiography. (B) The 64-MDCT volume-rendering image could not visualize the right IMA graft (arrow), and it was diagnosed as occluded graft. (64-MDCT = 64-slice multidetector computed tomography; IMA = internal mammary artery.)

4 Fig 3 Examples of 59-year-old male patient with false positive finding. Left IMA was anastomosed to the left anterior descending artery. Invasive coronary angiography showed the reverse blood flow from the native coronary artery to the graft, although the IMA graft was patent without significant stenosis by selective angiography. (A) (B) The image of 64-MDCT detected significant stenosis of the anastomosis (arrowhead), which was a false positive finding. (A) Curved planar reconstruction image, and (B) three-dimensional volume-rendering image. (64-MDCT = 64-slice multidetector computed tomography; IMA = internal mammary artery.)
