Abstract
MRA data is acquired from a large region of interest by translating the patient to successive stations at which successive portions of the MRA data set are acquired. Patient movement is chosen to track a bolus of contrast agent as it passes through the region of interest to achieve maximum image contrast. In one embodiment a stationary local coil is supported adjacent the patient to acquire the MRA data and in another embodiment a multi-segment local coil moves with the patient and its segments are sequentially switched into operation.
