摘要
目的:讨论MSCT在不典型胃肠道间质瘤(GIST)良、恶性诊断中的应用价值。方法:调取2009年1月至2013年1月间附属中山医院收治的23例有明确病理诊断的胃间质瘤患者影像资料,根据患者的病理诊断分为高度恶性组(12例)和低度恶性组(11例),记录两组瘤体部位、生长方式、大小、形态、边界、动脉期强化程度、溃疡、坏死囊变及钙化等情况,采用SPSS17.0进行数据处理分析。结果:入组的23例患者均为不典型胃肠道间质瘤患者,其中带蒂游走3例,完全囊变型8例,交界区7例,不规则型5例。两组患者在肿瘤直径、中心液化坏死、强化程度、肿瘤形态及肿瘤边界等方面具有统计学意义(x2=15.683,x2=10.145,x2=16.130,x2=19.326,x2=9.224;P<0.05)。结论:应用螺旋CT检查不典型GIST,可以根据影像特点对瘤体进行良、恶性的定性分析诊断,值得临床推广应用。
Objective：To discuss the application value of MSCT in atypical benign and malignant gastric stromal tumor diagnosis. Methods：Twenty three patients that had definite pathological diagnosis of gastric stromal tumors image data were chosen in our hospital from January 2009 to January 2013, and patients were divided into highly malignant group （12 cases） and low malignant group （11cases） according to patient’s pathological dianosis. Tumor location, growth pattern, size, shape, boundaries, arterial phase enhancement level, ulceration, necrosis, cystic degeneration, calcification were recorded and the results were analyzed using SPSS17.0 for data processing. Results：Twenty three patients were all atypical gastrointestinal stromal tumors, and there were three cases of pedunculated walk, 8 cases od completely cystic, 7 cases of junction, 5 cases of irregular. There were statistically significant differencesin the tumor diameter, central liquefaction necrosis, the degree of enhancement, tumor morphology, tumor border（x2=15.683,x2=10.145, x2=16.130,x2=19.326,x2=9.224;P〈0.05）. Conclusion：Application of spiral CT is not typical GIST, according to the image characteristics of benign and malignant tumors of the qualitative analysis and diagnosis, worthy of clinical application.
