摘　　要：目的探讨儿童肝母细胞瘤(HB)电子计算机断层扫描(CT)、磁共振成像(MRI)表现差异及二者诊断价值。方法选取2016年8月至2021年8月在江西省儿童医院收治的疑似HB的77例患儿,均进行CT、MRI检查,记录两种检测方法图像表现,以病理检查为金标准,采用Kappa一致性对比分析两种检查方法及对HB患儿的诊断效能。结果77例HB患儿CT表现:60例为光滑类圆形肿块,17例呈不规则分叶形肿块,14例伴有钙化,12例瘤内出血,39例脏器血管受压。MRI表现:类圆形肿块42例,T1W1多见低信号,T2W1多见高信号,11例瘤内出血,T1W1为高信号,T2W1为混杂高信号,41例脏器血管受压。CT诊断HB的灵敏度、特异度、准确率、阳性预测值、阴性预测值和Kappa系数值分别为95.65%、75.00%、93.51%、97.06%、66.67%和0.669;MRI诊断HB的灵敏度、特异度、准确率、阳性预测值、阴性预测值和Kappa系数值分别为98.55%、75.00%、96.10%、97.14%、85.71%及0.778。结论MRI检查对HB具有较高的诊断价值,可以对疾病进行早期检查,为制订治疗方案提供支持。Objective To explore the differences in findings of computed tomography(CT)and magnetic resonance imaging(MRI)and their diagnostic value for hepatoblastoma(HB)in children.Methods A total of 77 children with suspected HB admitted to Jiangxi Children′s Hospital were enrolled beween August 2016 and August 2021.All underwent CT and MRI examinations.The image findings of the two methods were recorded.Taking pathological examination as the golden standard,the two methods were compared by Kappa consistency test.And their diagnostic efficiency for HB children was analyzed.Results In terms of CT findings:There were 60 cases with smooth and quasi-circular lumps,17 cases with irregular and lobular lumps,14 cases with calcification,12 cases with intratumoral hemorrhage and 39 cases with visceral vessel compression.In terms of MRI findings:There were 42 cases with quasi-circular lumps(low signals on T1W1 and high signals on T2W1),11 cases with intratumoral hemorrhage(high signals on T1W1,mixed high signals on T2W1)and 41 cases with visceral vessel compression.The sensitivity,specificity,accuracy,positive predictive value,negative predictive value and Kappa coefficient values of CT and MRI in the diagnosis of HB were 95.65%,75.00%,93.51%,97.06%,66.67%,0.669 and 98.55%,75.00%,96.10%,97.14%,85.71%,0.778,respectively.Conclusion The diagnostic value of MRI is relatively higher for HB.It can be applied in the early examination and provide support for formulating treatment plans.
