摘　　要：目的 分析多层螺旋计算机断层扫描(MSCT)与超声内镜(EUS)对胃间质瘤美国国立卫生研究所(NIH)危险度分级的评估价值。方法 选取本院100例胃间质瘤患者,均经手术病理学结果证实,术前接受MSCT与EUS检查,比较NIH低危组与NIH中高危组MSCT图像特征、EUS参数与图像特征,采取受试者工作特征(ROC)曲线分析MSCT与EUS评估NIH危险度分级价值。结果 两组MSCT图像中肿瘤形态、钙化、CT强化程度比较无显著差异(P>0.05),NIH中高危组肿瘤最大径明显大于NIH低危组(P<0.05),密度不均匀占比明显高于NIH低危组(P<0.05);两组EUS所示肿瘤位置、边界、形状、起源层次、囊性变比较无显著差异(P>0.05),NIH中高危组表面溃疡、钙化占比明显高于NIH低危组(P <0.05),灰度标准偏差以及灰度平均值明显高于NIH低危组(P<0.05);MSCT、EUS及MSCT联合EUS评估AUC分别为0.851、0.869、0.935,联合评估敏感度86.42%,特异度94.59%。结论 MSCT与EUS均对胃间质瘤NIH危险度分级具有一定评估价值,二者联合具有较高评估效能。Objective To analyze the value of multi-slice spiral computed tomography(MSCT)and endoscopic ultrasonography(EUS)in the National Institutes of Health(NIH)risk classification of gastric stromal tumors.Methods 100 patients with gastric stromal tumors confirmed by surgery and pathology were selected.All patients received MSCT and EUS before surgery.MSCT image features,EUS parameters and image features of the NIH low-risk group and the NIH medium to high-risk group were compa red.The value of MSCT and EUS in evaluating NIH risk classification was analyzed using the receiver operating cha racteristic(ROC)curve.Results For MSCT images,there was no significa nt difference in tumor morphology,calcification,or CT enhancement between the two groups(P>0.05).The maximum diameter of tumors in the NIH medium to high-risk group was significantly larger than that in the NIH low-risk group(P<0.05),and the proportion of uneven density was significantly higher than that in the NIH low-risk group(P<0.05).EUS showed that there was no significant difference in the location,boundary,shape,origin,and cystic changes of tumors between the two groups(P>0.05).The proportions of surface ulcer and calcification in the NIH medium to high-risk group were significantly higher than those in the NIH low-risk group(P<0.05).The standard deviation and average value of grayscale were significantly higher than those in the NIH low-risk group(P<0.05).The AUC of MSCT,EUS,and MSCT combined with EUS were 0.851,0.869,and 0.935,respectively.The sensitivity and specificity of combined evaluation were 86.42%and 94.59%.Conclusion Both MSCT and EUS have ce rtain value in evaluating NIH risk classification of gastric stromal tumors,and com bination of the two has relatively high efficacy.
