A non-contrast-enhanced peripheral MR venography method
is proposed which generates high-contrast 3D venograms
directly using a single acquisition. The proposed method
combines velocity-selective magnetization preparation
for suppressing arterial signal and transient balanced
SSFP readout for suppressing muscle signal. The sequence
parameters are optimized to maximize vein-to-background
contrast and validated in vivo. The feasibility of
visualization of the entire peripheral venous systems
using multi-station is demonstrated in healthy subjects.
