入选标准
- •Patients with abdominal tumors:
- •all patients were pathologically diagnosed with abdominal tumors;
- •The clinical case data of all patients were complete, and complete follow-up was obtained, with clear information on medical visits, operation time and survival status within 2 years. If the cause of death is unknown, it will be recorded as censored data;
- •All patients had no history of active abdominal bleeding, no serious infection or other abdominal diseases that affected the observation of CT imaging within 3 months before surgery.
- •Non-tumor population:
- •all patients have complete clinical case data, complete abdominal CT, no history of malignant tumors, no serious infections or other abdominal diseases that affect the diagnosis and observation of CT imaging.
排除标准
- •Cases in which contrast-enhanced or noncontrast CT images show unclear lesions, with significant noise and artifacts;
