* 使用 CT 協議（180mAs，120kV，1.0pitch）進行衰減校正。
* 每項研究包括一個 CT 體積、一個 PET 體積以及融合 PET 和 CT 圖像：CT 分辨率為 512 × 512 像素，1mm × 1mm，PET 分辨率為 200 × 200 像素，4.07mm × 4.07mm，切片厚度和層間距為 1mm。

    * t-test
    * LASSO-Cox regression
    * Nomograms predicting 1-, 2-, and 3-year survival were established
    * slice thickness: 5 mm, slice interval: 5 mm
    * Multiphase abdominal CT scan was performed in the hepatic arterial phase at 25–30 s, portal venous phase at 70–80 s, and equilibrium phase at 150 s.
    * 63 patients(41:22)
