This study investigated the reproducibility of the recently developed improved Motion Sensitized Driven Equilibrium (iMSDE) technique for MR imaging of the coronary vessel wall at 3T. 19 volunteers underwent MRI of the right coronary artery lumen and vessel wall twice. Lumen diameter and vesselwall thickness measurements were performed, and measurements of the two scanning sessions were compared. In 15/19 volunteers two measurements of both coronary lumen and vessel wall were acquired successfully. This study demonstrated that iMSDE is able to visualize the coronary vessel wall of healthy volunteers at 3T with good reproducibility of lumen diameter and wall thickness measurements.
