Objective: To evaluate the clinical application value of enhanced CT in the diagnosis of gastrointestinal stromal tumors (GISTs). Methods: This study selected clinical and CT scan data from 62 patients with gastrointestinal stromal tumors between January 2023 and May 2024. The detection efficacy of different diagnostic methods was compared, and the CT imaging characteristics based on risk classification and tumor location were analyzed. Patients were divided into two groups: gastric GIST and small intestine GIST, and the CT features and CT values were analyzed. Results: Enhanced CT scanning was superior to conventional CT in detecting gastrointestinal stromal tumors (p < 0.05). There were significant differences in tumor risk, morphology, calcification, necrosis, boundaries, vascularity, and size (p < 0.05), but no significant differences in calcification, necrosis, and tumor internal features between the two groups (p > 0.05). Significant differences were observed in tumor morphology and growth characteristics between the gastric GIST group and the small intestine GIST group (p < 0.05), and the CT values in the gastric GIST group were consistently lower than those in the small intestine GIST group (p < 0.05). Conclusion: Enhanced CT scanning improves the detection rate of gastrointestinal stromal tumors, reduces the risk of missed diagnoses and misdiagnoses, helps determine pathological grade and tumor nature, and shows differences in malignancy between tumors in different locations, providing a reliable basis for clinical decision-making.
