Figure 3 Three-dimensional multislice spiral computed tomography reconstruction (volume rendering) of a venous graft to the circumflex coronary artery with proximal anastomosis to the descending aorta. This graft was missed by invasive coronary angiography.

Figure 4 Stented graft that was classified as significant in-stent stenosis due to a lack of contrast distal of the stent. The diagnosis was approved by invasive coronary angiography (left = maximum intensity projection; right = volume rendering technique).
