All imaging data included three sets of images from three different scanners: preoperative T1w (weight), T2w, and contrast enhancing T1w (CE-T1w) portal venous phase MR images. T2w was respiratory triggering and CE-T1w was performed following the intravenous injection of 0.1 mmol/kg contrast medium (Gadodiamide) as rate = 2 mL/s. The portal venous phase (60 s post-injection) was collected. The details of MRI protocol were shown in Additional file Preoperative T1w, T2w, and CE-T1w imaging were used to extract radiomics features.
