“…The efficacy of 16-and 64-slice MDCT in examining vein and arterial graft stenosis (more than 50% luminal narrowing) has been evaluated (70)(71)(72)(73) (Figure 4). As with graft patency, 64-slice MDCT was capable of assessing stenosis in 98% of all vein and arterial grafts.…”

“…In this study, no case of graft occlusion showed any additional patent segments or a patent proximal segment that was longer than 15 mm. Graft patency could not be determined when selective graft angiography was not performed: this was caused by the limited accessibility of complex composite grafts or by grafts without metallic markers (10). In this case, MSCT accurately demonstrated patency or occlusion, and this is an advantage of MSCT over conventional graft angiography.…”

Purpose:We wanted to evaluate the utility of multi-slice computerized tomography (MSCT) for assessing coronary artery bypass graft patency and/or occlusion. Materials and Methods: For 24 patients, both conventional angiography and CT angiography with 4-MSCT were performed within seven days of one another in order to evaluate the accuracy of MSCT with regard to graft patency and/or occlusion. A follow-up CT angiogram was performed in patients with and without symptoms (n=11, n=34, respectively) with 4-or 16-MSCT. We retrospectively compared the results of MSCT to those of conventional coronary graft angiography. Results: Sixty-five grafts were evaluated for the accuracy of MSCT. Six of those 65 were occluded. The sensitivity, specificity, positive predictive value and negative predictive values of MSCT for the diagnosis of graft occlusion were 100% (6/6), 98% (58/59), 86% (6/7) and 100% (58/58), respectively. Patency could not be determined by angiography in two grafts; however, the grafts proved to be patent on MSCT. On follow-up, new graft occlusions in the asymptomatic patients were detected by MSCT in 8.2% of the previously patent grafts at the two years post-op, and in 15.2% at the three years post-op. Conclusion: MSCT is a practical and accurate noninvasive diagnostic tool for following up coronary artery bypass grafts.

“…The detection of graft-occlusion using the 16-slice CT-scanner is quite reliable (Table 7) while the detection of non-occlusive stenoses is more problematic (47)(48)(49)(50)(51)(52)(53) . The 64-slice scanners perform slightly better, but evaluation of a post-bypass patient should include not only the bypass grafts but also the run-off native coronary segments distal to the graft anastomosis and non-grafted native coronary segments ( Figure 6).…”

MSCT Coronary Angiography is a fast developing non-invasive diagnostic technique that can detect a coronary stenosis. The detection of a coronary stenosis is hampered by limited image quality and by motion artefacts and extensive calcifi cations. However, MSCT-coronary angiography is highly reliable to rule out coronary stenosis. The role of MSCT-coronary angiography in the diagnostic work-up of coronary artery disease needs further research. ABSTRACTFIGURE 1: The X-ray tube and the detectors rotate in an opposing position of the gantry around the patient. A collimated X-ray beam is passed through the patient and the attenuated X-ray beam is collected on the detectors while the patient on the couch is continuously advanced through the gantry. 64 parallel detector rows acquire the data in a very short scan time.
