Fig. 5.
Stenosis of the transverse sinus (white arrows). (A) shows a 3D angiographic view based on the PC VIPR data performed with MIMICS Innovation Suite (Materialise, Ann Arbor, MI; blue = venous, red = arterial). For hemodynamic analyses, color-coding was achieved based on pressure differences (B) and velocity information (C). All data was derived from a singular PC HYPR Flow acquisition. A marked drop in pressure across the stenotic segment and elevated velocities with the stenosis can be appreciated. Visualization courtesy of Ben Landgraf, BS, University of Wisconsin – Madison.
