In order to test MRI ability to detect the number and the sites of coronary artery by-pass grafts (CABGs), 22 patients with CABGs were studied. The detection of a neo-vessel in even one of the examination slices was considered as positive for the study, disregarding the difference between its origin and course. With such a criterion, MRI total percentage of vascular bridges identification resulted in 76.1% (51/67) with very low values for CABGs implanted on diagonal, obtuse marginal and posterior descending vessels (11/24 = 45.8%). These results lead to the conclusion that, although MRI has some advantages in the identification of CABGs implanted on the main coronary vessels in the early post-operative period, its extensive use cannot be proposed at the present state of the art.
为了测试磁共振成像（MRI）检测冠状动脉旁路移植术（CABG）的数量和部位的能力，对22例接受CABG的患者进行了研究。在任何一个检查层面中检测到一条新血管即视为该研究阳性，而不考虑其起源和走行的差异。采用这一标准，MRI对血管桥的总体识别率为76.1%（51/67），对于植入对角支、钝缘支和后降支血管的CABG识别率非常低（11/24 = 45.8%）。这些结果得出的结论是，尽管MRI在术后早期识别植入主要冠状动脉血管的CABG方面具有一些优势，但就目前的技术水平而言，尚不能广泛应用。
