# Dataset:
## A Large-Scale CT and PET/CT Dataset for Lung Cancer Diagnosis (Lung-PET-CT-Dx)

* 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。

* [Predicting survival for hepatic arterial infusion chemotherapy of unresectable colorectal liver metastases: Radiomics analysis of pretreatment computed tomography](https://sciendo.com/es/article/10.2478/jtim-2022-0004)
* 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)
