Axial SW MR images obtained at 3 T (20/30; flip angle, 15°; bandwidth, 100
Hz/pixel; voxel size, 0.5 × 1.0 × 2.0 mm; FOV, 256 ×
256 mm). Original magnitude image (a), original phase image (b),
processed single-section magnitude image (c), and minimum intensity
projection through eight sections (d) show enhancement of the veins and globi
pallidi (arrowheads in b–d), which are seen as dark structures.
There is also increased visibility of cortical fibers connecting adjacent sulci (arcuate
fibers) (arrows in b–d), especially on phase (b) and
processed magnitude (c) images. The thick (16-mm) minimum intensity
projection SW image (d) shows dark vessels, with increased depiction of small
veins.
