目的：探讨多层螺旋CT在胃肠道间质瘤( GIST)定位和定性中的诊断价值。方法：对本院30例手术病理证实为胃肠间质瘤的患者的CT影像特点进行回顾性分析。均行16层螺旋CT平扫和增强扫描，探讨病灶位置、大小及有无坏死等情况。结果：胃肠道间质瘤单发患者21例、多发9例；其中17例肿瘤部位在胃部、8例位于小肠、5例位于直肠。19例向腔内外同时生长、8例向腔外生长、3例向腔内生长。恶性GIST 强化不均匀，可有邻近脏器侵犯。16层螺旋CT定性准确率为83.3％(25/30)、定位准确率90.0％(27/30)。结论：CT 增强扫描有利于GIST的定位诊断及对肿瘤良恶性质的判断，能准确显示肿瘤的部位、形态、大小，是目前检查GIST的重要方法之一。

Objective:To investigate the diagnosis values of multi-slice CT ( MSCT ) on diagnosis of gastrointestinal stromal tumors ( GIST) . Methods:The CT characteristics of 30 tumors of pathological confirmed GIST in our hospital were retrospectively analyzed. All patients were scanned with unenhanced and enhanced 16-slice CT, and then the location, size and necrosis of lesions were analyzed. Results:Among all 30 cases, single lesions of GIST were 21 cases, and motile lesions of GIST were 9 cases. And 17 cases located at stomach, 8 cases at small intestine, and 5 cases at rectum. There were 19 cases simultaneously inside and outside the chamber, 8 cases of external cavity growth, and 3 cases of intracavity growth. The malignant GIST exhibited inhomogeneous enhancement and invasion to adjacent organs. Accuracy of 16-slice CT diagnosis for qualitative analysis was 83. 3% ( 25/30 ) and for location was 90. 0% ( 27/30 ) of GISTs. Conclusion: CT enhanced scan benefits the localization diagnosis of GIST and the determination of benign or malignant tumors. It could accurately show the location, form and size of tumors, which is one of the significant methods to examine GIST.
