Recruiting

• Conditions: Abdominal Neoplasm

• Registration Number: NCT06614179
• Lead Sponsor: Xiangdong Cheng

Brief Summary

Abdominal noncontrast scan and contrast-enhanced CT were used to establish a screening and diagnostic model for abdominal tumors

Detailed Description

Secondary objective: To establish a grading model of abdominal tumors based on clinical indicators Exploratory Objective: To include CT scans in large-scale non-tumor populations for validation and to improve model accuracy Certainty

Inclusion Criteria

• 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;

• 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.

Exclusion Criteria

• Cases in which contrast-enhanced or noncontrast CT images show unclear lesions, with significant noise and artifacts;
