Drawing of the region of interest (ROI). A 65-year-old male with histopathologically confirmed hepatocellular carcinoma within segment 6/7 and a tumor size of 7.4 cm × 7.0 cm. (a) CT image (1 mm) of the largest cross-sectional area of the tumor in the routine unenhanced phase. (b) The manually delineated ROI around the lesion for the T-RO model. (c) The ROI for the PT-RO model was automatically expanded 2 cm from the lesion, and if the ROI was beyond the parenchyma of the liver after expansion, the portion beyond the parenchyma was manually removed
