- Fig 1.
PC-MR imaging magnitude (left) and phase (right) images showing the neck level for a healthy patient. Artery and vein contours were traced on the images semiautomatically; arteries appear bright, whereas veins appear dark on phase images. Type I veins: IJV; type II veins: AVPV: anterior venous plexus vein; EPDV: epidural vein; DCV, deep cervical vein; type III veins: EJV, external jugular vein. Arteries: ICA; VA, vertebral artery.

Comparison of total mean flows (mL/s) for vessel types between diagnostic groups. The error bars represent standard errors of the mean.

Comparison of total mean venous flow (mL/s) by vessel type among nonstenotic-MS (NST-MS), stenotic-MS (ST-MS), and HC groups. The error bars represent standard errors of the mean.
