Objective To explore the value of the respiratory-triggered three-dimensional (3D) true steady-state free-precession (SSFP) combined with time spatial labeling inversion pulse (T-SLIP) in the selective visualization of hepatic arteries, portal veins and hepatic veins, with an attempt to improve the understanding of non-contrast-enhanced magnetic resonance angiography (NCE-MRA) for liver.
Methods The clinical data of four patients who underwent NCE-MRA in our hospital from October 2010 to May 2011 were retrospectively analyzed.
Results Selective visualization of hepatic vessels was successfully acquired in all cases. No anatomical variation of hepatic arteries was found. Two cases had portal vein invasion and one case had broadening of main portal vein. One case had hepatic veins involvement, accompanied with the opening of accessory hepatic vein.
Conclusion 3D true SSFP scan with T-SLIP can be effectively applied for the selective NCEMRA of hepatic vasculature.
