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.
