ABSTRACT:
A method is provided for acquiring MR image data pertaining to a coronary artery which is in motion between end-diastolic and end-systolic maximum excursion positions, respectively, during a cardiac cycle. The method comprises the step of tracking the location of the artery during the cardiac cycle as the artery moves between the positions of maximum excursion. The method further comprises acquiring MR data at a number of locations during the cardiac cycle in a region lying between the maximum excursion positions, each having the excitation or acquisition scan locations adjusted during the MR scan so as to substantially coincide with the location of said artery at the time of data acquisition.
