Liver MRI Imaging Protocol

pMR was performed on 1.5T (Magnetom Avanto; Siemens Healthcare, Erlangen, Germany) or 3T MR system (Magnetom Verio with Tim system; Siemens Health care, Erlangen, Germany) with multichannel phased array coils (16 or 32 channels) using our institutional standard liver p-MR protocol, as previously described [31 (link)]. In brief, axial and coronal T2 HASTE, echo-planar imaging two-dimensional diffusion (b 100, 600), precontrast and postcontrast 3D, fat-saturated gradient echo T1-weighted volumetric interpolated breath-hold examinations (VIBE) before contrast, and after intravenous injection of 0.025 mmol/kg gadoxetic acid in the arterial phase, portal venous phase, transitional phase, and the hepatobiliary phase (20 min post-contrast injection).
