Purpose: Contrast-enhanced 3D MRA (CE-3DMRA) has become a routine application in the assessment of supraaortic steno-occlusive disease. However, acquisition time has to be chosen according to arterial bolus characteristics limiting spatial resolution and/or the number of acquired slices, i.e. the anatomic coverage. Parallel imaging allows for a reduction of acquisition time at the expense of signal-to-noise ratio while spatial resolution is maintained. Supraaortic MRA at 3.0T offers increased signal-to-noise and theoretically holds promise to use higher acceleration factors (i.e. >2) in parallel imaging while ma…
