First pass, 3D gadolinium-enhanced venography of the
jugular veins is difficult to perform when seeking both
large spatial coverage and high spatial resolution.
Particularly when considering routine clinical 1.5 T
systems that may not be equipped with dense phased
arrays for parallel imaging, capturing the venous phase
without overwhelming arterial enhancement becomes
difficult. We test first pass Gd-enhanced venography
encompassing a large 3D coronal field-of-view at 0.64
mm3 voxel dimensions using a single 36 sec acquisition.
High resolution enables proper assessment of venous
narrowing. We report on the feasibility in application
to 60 subjects, 30 with multiple sclerosis (MS) and 30
healthy controls to examine cerebral venous drainage.
