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.
