本研究旨在评价对比增强MRI显示冠状静脉的能力，并通过金标准X线静脉造影进行验证，并确定MRI是否可以显示用于LV电极导线植入的冠状静脉分支。19例接受CRT的患者在治疗前1周接受了1.5T心脏MRI。冠状静脉图像采集采用3D、导航和ECG门控、对比增强、反转恢复、快速低角度拍摄（FLASH）序列。在CRT手术期间进行X线静脉造影，以成像冠状静脉解剖结构和LV电极导线位置。MRI冠状静脉图像按0 - 3级评分（0 =不存在，1 =差，2 =好，3 =优）。MRI和X线静脉造影图像也使用二进制可见/不可见方案进行分级，以比较冠状静脉的可见性。冠状窦、后室间、左室后静脉、左缘静脉和前室间的平均可见性评分分别为3.0 ± 0.2、2.3 ± 0.7、1.6 ± 1.1、1.9 ± 0.8和2.4 ± 0.9。与X线静脉造影相比，MRI能够显示90%的静脉和用于LV电极导线植入的所有静脉。用于LV电极导线植入的静脉在MRI图像上的平均静脉图像质量评分为1.9。对比增强MRI能够可视化90%的冠状静脉解剖结构，并且能够可视化所有患者中用于LV电极导线植入的静脉。
The aims of this study were to evaluate the ability of contrast-enhanced MRI to visualize the coronary veins with validation by the gold standard, X-ray venography, and to determine whether MRI can visualize the coronary vein branch used for LV lead implantation. Nineteen (19) patients undergoing CRT received a cardiac MRI at 1.5T 1 week before treatment. Coronary vein images were acquired using a 3D, navigator- and ECG-gated, contrast-enhanced, inversion-recovery, fast low angle shot (FLASH) sequence. X-ray venography was performed during the CRT procedure to image the coronary venous anatomy and the LV lead location. MRI coronary vein images were graded on a 0 – 3 scale (0 = non-existent, 1 = poor, 2 = good, 3 = excellent). MRI and X-ray venogram images were also graded using a binary visible/not visible scheme to compare the visibility of the coronary veins. The mean visibility scores for the coronary sinus, the posterior interventricular, the posterior vein of the left ventricle, the left marginal vein, and the anterior interventricular were 3.0 ± 0.2, 2.3 ± 0.7, 1.6 ± 1.1, 1.9 ± 0.8 and 2.4 ± 0.9 respectively. When compared to X-ray venography, MRI was capable of visualizing 90% of veins and all of the veins used for LV lead implantation. The vein used for LV lead implantation had an average vein image quality score of 1.9 on MRI images. Contrast-enhanced MRI was capable of visualizing 90% of the coronary venous anatomy and was able visualize the vein used for LV lead implantation in all patients.
