MR Angiography of the intracranial perforating arteries. MR Angiography of the intracranial perforating arteries. Coronal Maximum Intensity Projection (MIP) of a 7 T Time-of-Flight (TOF) MRA, repetition time 16ms, echo time 3.3 ms, acquired voxel size 0.25×0.3×0.4 mm³, reconstructed voxel size 0.2×0.2×0.2 mm³, field-of-view 200x190×50 mm³, scan duration 9:54 min, performed in a 51-year-old male. Perforating lenticulostriate arteries (arrowheads) branching off from the middle cerebral arteries are clearly seen in both cerebral hemispheres.
