Feasibility of intracranial super-resolution QISS MRA acquired with (a) 1.0 mm and (b) 0.7 mm in-plane spatial resolution in a 36-year-old male. Resolution-matched 3D TOF protocols are shown in (c) and (d), respectively. Images are axial maximum intensity projections. Note the improved delineation of small intracranial arteries with QISS as compared to TOF MRA (arrows), at both spatial resolutions.
