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.
