摘　　要：目的 探讨CT在儿童纵隔神经母细胞瘤(NB)与节细胞神经母细胞瘤(GNB)的鉴别诊断价值.方法 选取纵隔NB患儿46例和纵隔GNB患儿30例,比较NB和GNB病灶CT征象差异.结果 NB和GNB病灶纵径、长轴径和短轴径比较差异无统计学意义(P>0.05);NB病灶边界模糊、转移及局部侵犯比例分别为71.74%和67.39%,明显高于GNB病灶(P<0.05);NB病灶动脉期CT值为(64.40±11.29)HU,明显高于GNB病灶(P<0.05);NB和GNB病灶平扫、静脉期CT值比较差异无统计学意义(P>0.05).结论 CT可用于儿童纵隔NB与GNB病灶鉴别诊断,病灶边界、转移及局部侵犯、动脉期CT值有一定诊断价值,值得临床使用.Objective To explore the value of CT in differential diagnosis of mediastinal neuroblastoma(NB)and ganglioneuroblastoma(GNB)in children.Methods 46 children with mediastinal NB and 30 children with mediastinal GNB were selected to compare the CT signs of NB and GNB lesions.Results There were no significant differences in longitudinal diameter,long axis diameter and short axis diameter between NB and GNB lesions(P>0.05).The proportion of blurred boundary,metastasis and local invasion of NB lesions were 71.74% and 67.39%,which were significantly higher than that of GNB lesions(P<0.05).The CT value of NB lesions at arterial phase was(64.40±11.29)HU,which was significantly higher than that of GNB lesions(P<0.05).There were no significant differences in CT value between NB and GNB in plain scan and venous phase(P>0.05).Conclusion CT has significant value in differential diagnosis of mediastinal NB and GNB lesions in children.The parameters such as lesion boundary,metastasis,local invasion and arterial phase CT value have certain diagnostic values,and it is worthy of clinical use.
