The recipient vessels after orthotopic liver transplantation (OLT) are often evaluated by CT and MRI, but the recipient vessels either may be contaminated by other vessel or may not be presented distinctly due to the individual hemodynamics changes. In addition, Gd or iodine contrast media are applied on CT and MRI for displaying the recipient vessel which may cause nephrogenic systemic fibrosis (NSF) or contrast-Induced Nephropathy. Therefore, a non-contrast magnetic resonance angiography (NC-MRA) is desirable to develop for presenting the recipient vessels. In this study, a new NC-MRA (Spatial LabEling with multiple invErsion pulses, SLEEK) has been applied to delineate the recipient vessel after OLT.
