non-gated single 20-sec breath-hold non-contrast-enhanced 3D-MRA technique
using bSSFP was developed and the feasibility of the proposed method for the
visualization of renal artery was compared using respiratory gated non-contrast-enhanced
time-SLIP 3D-MRA with several minutes of scan time. The single breath-hold
bSSFP-MRA technique was optimized in flip angle and the number of segmentations
to obtain excellent renal blood signal with maintaining about 20 sec breath-holding.
The proposed bSSFP-MRA technique gave equal to time-SLIP MRA in the
visualization of renal artery.
