[目的]分析并讨论胃肠间质瘤的MRI诊断价值和病理组织学的特点。[方法]选取2011年7月~2013年1月期间我院胃肠科收治的患有胃肠道间质瘤患者98例,按照系统分组法将98例患者分为使用MRI方法检查的观察组和使用超声检查的对照组。2组患者在上述检查之后均进行病理组织学分析。[结果]两种检查方法均能检测出胃肠道间质瘤,MRI检测的准确率为95.92%,而超声检查的准确率为67.35%,前者比后者准确率高约28.57%(P<0.05)。其中通过检查发现,病灶发生于胃部者比肠部和回盲部多约32.56%(P<0.05)。[结论]MRI对胃肠道间质瘤的诊断准确性高,诊断相对精准。虽然MRI检查的费用较其他影像方法高,但是还是值得在临床上广泛推广。
[Objective] To analyze and discuss the diagnostic value of MRI and histopathology of gastrointestinal stromal tumors. [Method] A total of 98 patients with gastrointestinal stromal tumors admitted to our department of gastroenterology from July 2011 to January 2013 were enrolled. According to the systematic grouping method, 98 patients were divided into observation group And control group using ultrasound examination. Two groups of patients after the above examination were histopathologically analyzed. [Results] Gastrointestinal stromal tumors were detected by either method. The accuracy of MRI was 95.92%, while that of ultrasonography was 67.35%. The former was 28.57% higher than the latter (P < 0.05). The examination showed that lesions occurred in the stomach more than the intestinal and ileocecal about 32.56% (P <0.05). [Conclusion] The diagnosis of gastrointestinal stromal tumors by MRI is accurate and the diagnosis is relatively accurate. Although the cost of MRI examination than other imaging methods, but it is still worth widely clinical promotion.
