Preoperative hepatic vascular evaluation is of great importance in a variety of liver surgeries, including tumor resection and transplantation. An accurate depiction of hepatic vascular anatomy can help to prevent the complications and decrease the morbidity and mortality in liver surgeries. However, few studies have reported good image quality in hepatic vasculature imaging using non-contrast-enhanced MR angiography (NCE-MRA) because of the motion and complex structure. In recent years, some studies reported the potential of NCE-MRA with velocity-selective pulse train (VSMRA). In this study, we demonstrated the feasibility of VSMRA for imaging the hepatic vasculature with an off-resonance-robust velocity-selective pulse train at 3T.
