Abstract：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.
