Magnetom verio with tim system

CECT was performed using two scanners (Aquilion ONE or Aquilion 64, Toshiba CA, USA;). CECT protocol and parameters are summarized in (Supplementary Table 1). Patients also underwent EOB-MRI with a 1.5 T (Magnetom Avanto; Siemens Healthcare, Erlangen, Germany) or 3 T (Magnetom Verio with Tim system; Siemens Health care, Erlangen, Germany) MRI scanner with multichannel phased array coils (16 or 32 channels) using a standard liver EOB-MRI protocol (Supplementary Table 2). Gadoxetic acid (Primovist or Eovist, Bayer AG, Germany) was administered intravenously with a power injector (Medrad® Spectris Solaris® EP MR Injection system, Bayer Healthcare, Whippany, USA).

CECT was performed on either of two scanners (Aquilion ONE or Aquilion 64, Toshiba CA, USA;) with a standardized multiphasic liver protocol (Additional file 1). EOB-MRI was performed on a 1.5 T (Magnetom Avanto; Siemens Healthcare, Erlangen, Germany) or 3 T (Magnetom Verio with Tim system; Siemens Health care, Erlangen, Germany) MRI scanner with multichannel phased array coils (16 or 32 channels) using a standardized liver protocol (Additional file 2).

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).
