To evaluate the use of magnetic resonance (MR) imaging in the detection of coronary artery bypass grafts (CABGs), 20 patients with grafts underwent electrocardiographic-gated MR study. The number and location of CABGs in each patient were not known at the time of study. The number of grafts seen with MR imaging was compared with the actual number of grafts determined from the operative or angiographic report. On the prospective review of the images, 54 of 64 grafts (84%) were detected, with three false-positive results. When the images were reevaluated with knowledge of the type and number of grafts in each patient, 56 of 64 grafts (88%) were detected. Forty-one of the 46 (89%) left grafts, 15 of the 18 (83%) right grafts, and five of the 11 (45%) internal mammary grafts were detected. Although resolution was not adequate to determine the presence of graft stenosis, this early experience indicates that patent CABGs can be seen with MR imaging.
为评估磁共振（MR）成像在检测冠状动脉旁路移植术（CABG）中的应用，对20例接受移植术的患者进行了心电图门控MR研究。研究时，每位患者的CABG数量和位置均未知。将MR成像所显示的移植血管数量与手术或血管造影报告中确定的实际移植血管数量进行比较。在对图像进行前瞻性评估时，64条移植血管中有54条（84%）被检测到，有3例假阳性结果。当根据每位患者的移植血管类型和数量重新评估图像时，64条移植血管中有56条（88%）被检测到。46条左移植血管中的41条（89%）、18条右移植血管中的15条（83%）以及11条乳内移植血管中的5条（45%）被检测到。尽管分辨率不足以确定移植血管狭窄的存在，但这一早期经验表明，MR成像能够显示通畅的CABG。
