胃肠道间质瘤的CT影像学征象及其病变危险度分级的临床分析

Clinical Analysis of CT Imaging Signs and Lesion Risk Degree Classification of Gastrointestinal Stromal Tumor

目的探究胃肠道间质瘤(GIST)的CT影像学征象和病变危险度分级。方法方便选择2011年4月—2017年4月该院GIST患者80例,均采取多层螺旋CT横断位扫描,对其影像学征象、病变危险度分级展开回顾性分析。结果46例低度危险,23例中度危险,11例高度危险;不同危险程度的患者其肿瘤生长方式、平扫密度、最大径等指标对比差异有统计学意义(P<0.05)。结论 CT影像学应用在GIST诊断中能通过分析其征象判定病变危险度,进而提高治愈率。

Objective To study the CT imaging signs and lesion risk degree classification of gastrointestinal stromal tumor.Methods80cases of GIST patients in our hospital from April2011to April2017were convenient selected and used the multi-spiral CT transversal scan,and the imaging signs,lesion risk degree classification were retrospectively analyzed.Results46cases had the low-degree risk,23cases had the moderate-degree risk,11cases had the high-degree risk,and the differences in the tumor growth way,plain density,maximum diameter between patients of different risk degrees,and the differences were statistically significant(P<0.05).Conclusion The application of GIST diagnosis of CT imaging can analyze and determine the lesion risk degree thus improving the cure rate.
