目的分析胃肠道间质瘤（GIST）的CT表现特点，探讨CT对该肿瘤的诊断价值。方法回顾性分析经手术病理证实的GIST 25例，术前均行CT平扫和（或）增强检查。结果肿瘤发生于胃部16例，空肠4例，食管1例，回肠3例，直肠1例，病灶多呈圆形或类圆形。平扫：肿瘤呈均匀等密度者18例；肿瘤呈密度不均者7例。增强扫描：病灶呈均匀强化者4例；病灶呈不均匀强化者17例。25例GIST中，良性11例，肿块直径多＜5cm，边界清楚，多呈均匀强化；恶性者15例，肿块直径均＞5cm，边界常不清楚，多呈不均匀强化，2例出现转移灶。结论CT检查对GIST的定位准确，对肿瘤良恶性的判断亦很有价值。

Objective To analyze the CT manifestation features of gastrointestinal stromal tumor (GIST) and explore the CT diagnosis value for the tumor. Methods 25 cases with GIST confirmed by surgical pathology were retrospectively analyzed. The patients were done preoperative CT scan and/or enhanced checks. Results There were 16 cases that the tumor exited in the stomach, 4 cases exited in jejunum, 1 case exited in esophagus, 3 cases exited in ileum, 1 case exited in rectum, and the lesion showed rounded or quasi-circular. There were 18 cases with uniform density by the scan and 7 cases with uneven density by the scan. There were 4 cases with uniform strengthening by the enhanced checks and 17 cases with uneven strengthening by the enhanced checks. In 25 patients with GIST, 11 cases were benign, and had the tumor diameter less than 5 cm, the clear border, and were uniform strengthening; 15 cases were malignant, and had the tumor diameter more than 5 cm, the unclear border, and were uneven strengthening, of all 2 cases happened metastases. Conclusion CT examination for GIST has accuracy position and the value for the determinations on benign and malignant tumor.
