摘　　要：目的探究多层螺旋CT(MSCT)在胃间质瘤患者鉴别诊断中的应用价值。方法回顾性分析2014年3月至2018年2月我院收治的35例胃间质瘤患者的影像学资料,所有患者均行MSCT扫描,并经手术、病理及组织学证实。以病理检查结果作为金标准,分析MSCT诊断胃间质瘤的准确度及不同性质胃间质瘤的MSCT征象特点。结果以病理结果作为金标准,MSCT未能定位或定位错误7例,定位准确率为80.00%(28/35);恶性及潜在恶性病例中病灶大小≥5mm、发生坏死、侵犯周围组织、门静脉及延迟期不均匀减退的发生率高于良性病变病例(P<0.05)。结论MSCT可对大多数胃间质瘤进行准确定位及定性诊断,且根据部分特殊征象有助于判断肿瘤是否恶性及潜在恶性。Objective To investigate the application value of multi-slice spiral CT(MSCT)in differential diagnosis of patients with gastric stromal tumor.Methods The imaging data of 35 patients with gastric stromal tumor admitted to the hospital from March 2014 to February 2018 were analyzedretrospectively.All patients underwent MSCT scan and were confirmed by surgery,pathology and histology.Taking the pathological examination results as the golden standard,the coincidence for the diagnosis of gastric stromal tumor by MSCT and the MSCT signscharacteristics of different properties of gastric stromal tumor were analyzed.Results Taking the pathological results as the golden standard,there were 7 cases not located or wrongly located by MSCT.The accuracy of localization was 80.00%(28/35).The incidence of the lesion size not less than 5 mm,occurrence of necrosis,invasion of surrounding tissues,uneven reduction of portal veins and delay phase in malignant and potentially malignant cases was higher than that in benign lesions cases(P<0.05).Conclusion MSCT can accurately locate and qualitatively diagnose the majority of gastric stromal tumors.According to some special CT signs,it is helpful to judge whether the tumors are malignant or potential malignant.
