Case 2. A 58-year-old woman with an unruptured multilobulated aneurysm at the left MCA bifurcation. A, 3D TOF MRA. B, 4D flow MR imaging demonstrates inflow entering through the distal neck of the aneurysmal orifice. The angle of the section plane that identifies the aneurysmal orifice with respect to the imaging section direction on 3D TOF MRA is 25°. C, 4D flow MR imaging demonstrates the inflow zone (red). D, TC 3D MRA depicts the putative inflow zone located on the distal neck. Red indicates the area where the MR signal intensity exceeds 320.
