MCT-LTDiag

This dataset is designed to support the development of artificial intelligence models for the differential diagnosis of liver tumors. It comprises contrast-enhanced CT scans of NIFTI format from five tumor categories: primary malignant tumors (hepatocellular carcinoma [HCC] and intrahepatic cholangiocarcinoma [ICC]), metastatic tumors (breast cancer liver metastasis [BCLM] and colorectal cancer liver metastasis [CRLM]), and a primary benign tumor (hepatic hemangioma [HH]). Each case includes four imaging phases: non-contrast (NC), arterial phase (AP), portal venous phase (PVP), and delayed phase (DP).
