Single transaxial slice of radioembolization pre-treatment studies and segmentation result (patient ID BI01 from training set in our database): a the CT and activity image of the 99mTc-MAA SPECT/CT scan. Correction for scatter and attenuation is applied and a phantom-based calibration factor is used to obtain images of absolute 99mTc concentration [kBq/cc]. b CBCT images with contrast enhancement facilitating delineation of the right and left liver lobe. c The CT and PET of the 18F-FDG PET/CT study. d The segmented liver, tumor, and LPTs
