This is the official repo of the article "MPBD-LSTM: A Predictive Model For Colorectal Liver Metastases Using Time Series Multi-phase Contrast-Enhanced CT Scans" (MICCAI 2023). Code will be uploaded shortly.

Our dataset consists of 269 patients in total, with a positive rate of 25.7%. Aside from the plain scan phase, it has 2 additional contrast-enhanced phase: the portal venous phase (V) and the arterial phase. It's collected based on the following rules:

• No tumor appears on the CT scans. That means patients have not been diagnosed as CRLM when they took the scans.
• Patients were previously diagnosed with colorectal cancer TNM stage I to stage III, and recovered from colorectal radical surgery.
• Patients have two or more times of CECT scans.
• We already determined whether or not the patients had liver metastases within 2 years after the surgery, and manually labeled the dataset based on this.
• No potential focal infection in the liver before the colorectal radical surgery.
• No metastases in other organs before the liver metastases.
• No other malignant tumors.

For more details, please refer to the article.
We are further doing more experiments for the task, will upload the code once it's finished.
