摘要
目的:探讨超声(US)和多层螺旋CT(MSCT)两种检查方法在胃肠道间质瘤(GIST)诊断中的应用价值。方法:选择2015年2月到2017年2月在我院诊治的疑似胃肠道间质瘤患者60例作为研究对象,均进行超声与MSCT检查,判定诊断效果与检查特征。结果:60例患者经过病理诊断为胃肠道间质瘤35例,诊断为非胃肠道间质瘤25例,胃肠道间质瘤35例中超声表现为低回声32例,伴后方声影27例,内部血流丰富23例,轮廓模糊24例;非胃肠道间质瘤25例中超声表现为低回声8例,伴后方声影6例,内部血流丰富9例,轮廓模糊5例,两组超声特征对比有明显差异(P<0.05)。胃肠道间质瘤患者的CT增强成像参数AT(增强开始时间,Arrival time)、TTP(达峰时间,Time to peak enhancement)值明显低于非胃肠道间质瘤患者(P<0.05),而T1/2(强度半降时间,Time from peak to half)、AUC(曲线下面积,Area under the curve)与EI(增强强度,Enhanced intensity)值明显低于非胃肠道间质瘤患者(P<0.05)。US诊断胃肠道间质瘤的敏感性与特异性分别为80.0%和92.0%,MSCT诊断胃肠道间质瘤的敏感性与特异性分别为97.1%和100.0%,MSCT在胃肠道间质瘤诊断中的敏感性明显高于超声(P<0.05)。结论:US和MSCT检查均可应用于胃肠道间质瘤的诊断,其中MSCT检查效果更佳,具有很好的应用价值,应加以推广。
Objective To investigate the value of ultrasonography（ US） and multi-slice spiral CT（ MSCT） in the diagnosis of gastrointestinal stromal tumors（ GIST）. Methods From February 2015 to February 2017,60 patients with suspected GIST in our hospital were selected as the research objects. All the patients were examined by US and MSCT,thereby determining diagnostic effects and inspection characteristics. Results Sixty cases were pathologically diagnosed as 35 cases of gastrointestinal stromal tumors and 25 cases of non gastrointestinal stromal tumor. In the 35 cases of gastrointestinal stromal tumor,the sonographic findings were hypoechoic in 32 cases,accompanied by posterior acoustic shadows in 27 cases,abundant internal blood flow in 23 cases,and fuzzy contour in 24 cases. In the 25 cases of non gastrointestinal stromal tumor,ultrasound showed hypoechoic（ 8 cases）,acoustic shadows（ 6 cases）,rich internal blood flow（ 9 cases）,fuzzy contour（ 5 cases）. The comparison of two groups of ultrasound characteristics was significantly different（ P0.05）. In patients with gastrointestinal stromal tumors,the AT and TTP values of CT enhanced imaging parameters were significantly lower than those of non gastrointestinal stromal tumors（ P0.05）,while T1/2,AUC and EI values were also significantly lower than those of non gastrointestinal stromal tumors（ P0.05）. The sensitivity and specificity of gastrointestinal stromal tumor diagnosis were 80% and 92% for US,97% and 100% for MSCT respectively. The sensitivity of MSCT in diagnosis of gastrointestinal stromal tumors was significantly higher than that of ultrasound（ P 0.05）. Conclusion US and MSCT can be well used in the diagnosis of gastrointestinal stmmal tumors,while MSCT holds better application value and should be popularized.
