Analysis of Clinical Limitations of Plain Abdominal CT scan in Diagnosing Gastrointestinal Diseases in Primary Medical Institutions
Objective: To explore the application value and limitations of abdominal CT scans in the clinical diagnosis of gastrointestinal diseases in primary medical institutions. Methods: 2,300 patients who underwent abdominal CT scans in our hospital in 2025 were selected as the research subjects, and the preliminary diagnostic results of CT scans of all patients were counted. Then, the comprehensive clinical diagnosis results were used as the gold standard to analyze the accuracy, misdiagnosis rate and missed diagnosis rate of abdominal CT scans in diagnosing gastrointestinal diseases. Results: A total of 1,682 cases of various gastrointestinal diseases were detected by abdominal CT scans in 2,300 patients, and 618 patients had normal imaging findings. Based on the clinical comprehensive diagnosis results, the overall accuracy of abdominal CT scans in diagnosing gastrointestinal diseases was 74.32%, the missed diagnosis rate was 18.55%, and the misdiagnosis rate was 7.13%. Conclusion: Abdominal CT scans in primary medical institutions have basic diagnostic value for moderate to severe organic gastrointestinal lesions. However, affected by examination methods, equipment conditions and lesion characteristics, there are obvious limitations in clinical application and cannot fully meet the needs for precise diagnosis of gastrointestinal diseases.
