目的:分析多层螺旋CT(MSCT)诊断,评价MSCT的应用价值。方法:分析过去1年在我院就诊的47例胃肠道间质瘤(GIST)患者的相关资料。结果:胃部肿瘤24例,小肠肿瘤14例,肠系膜肿瘤7例,大肠肿瘤2例;其中有恶性GIST病例28例,CT表现为:肿瘤的直径5cm以上19例,瘤体内坏死5例,肿块边缘分叶状4例;良性19例,肿瘤直径在5cm以下,边界十分明显且清晰,密度相当均匀。所有病例都有CT检查敏感性,准确定位93.6%(44/47),定位的准确达到87.2%(41/47)。结论:GIST病例具有影像特点。GIST的检查方法是CT检查,CT检查可对GIST进行准确定位与定性,以此指导临床治疗有重要价值。
Objective: To analyze the value of multi-slice spiral CT (MSCT) in diagnosing MSCT. Methods: The data of 47 cases of gastrointestinal stromal tumors (GISTs) treated in our hospital in the past year were analyzed. Results: There were 24 cases of stomach tumor, 14 cases of small intestine tumor, 7 cases of mesenteric tumor and 2 cases of colorectal tumor. Among them, 28 cases had malignant GIST. The CT manifestations were as follows: the diameter of tumor was above 5cm in 19, the tumor necrosis in 5, 4 cases of edge lobulation; 19 cases of benign, tumor diameter below 5cm, the border is very clear and clear, the density is quite uniform. In all cases, the sensitivity of CT examination was 93.6% (44/47) accurately and 87.2% (41/47) correctly. Conclusion: GIST cases have imaging features. GIST examination method is CT examination, CT examination of GIST accurate positioning and qualitative, in order to guide the clinical treatment of great value.
