To compare two coronary vein imaging techniques using whole-heart balanced steady-state free precession (SSFP) and a targeted double-oblique spoiled gradient-echo (GRE) sequences in combination with magnetization transfer (MT) preparation sequence for tissue contrast improvement.

Materials and Methods:

Nine healthy subjects were imaged with the proposed technique. The results are compared with optimized targeted MT prepared GRE acquisitions. Both quantitative and qualitative analyses were performed to evaluate each imaging method.


Whole-heart images were successfully acquired with no visible image artifact in the vicinity of the coronary veins. The anatomical features and visual grading of both techniques were comparable. However, the targeted small slab acquisition of the left ventricular lateral wall was superior to whole-heart acquisition for visualization of relevant information for cardiac resynchronization therapy (CRT) lead implantation.


We demonstrated the feasibility of whole-heart coronary vein MRI using a 3D MT-SSFP imaging sequence. A targeted acquisition along the lateral left ventricular wall is preferred for visualization of branches commonly used in CRT lead implantation.
