CT结合MRI检查对小儿炎性肌纤维母细胞瘤的诊断效果分析

Analysis on Diagnostic Effect of CT Combined with MRI on Inflammatory Myofibroblastic Tumor in Children

目的探讨CT结合MRI检查对小儿炎性肌纤维母细胞瘤的诊断效果。方法回顾性分析本院2017年7月至2019年5月收治的30例炎性肌纤维母细胞瘤小儿患者的临床资料共30例。所有患者均接受CT检查和MRI检查,并对其检查图像进行分析,比较CT检查、MRI检查及两者联合检查对小儿炎性肌纤维母细胞瘤的诊断准确性、敏感性和特异性。结果CT检查对小儿炎性肌纤维母细胞瘤诊断灵敏性、特异性和准确性分别为76.66%、66.66%、83.33%,MRI检查灵敏性、特异性和准确性分别为83.33%、80.00%、90.00%,CT结合MRI检查诊断灵敏性、特异性和准确性分别为93.33%、96.66%、96.66%,MRI检查对小儿炎性肌纤维母细胞瘤的诊断灵敏性、特异性和准确性高于CT检查,但在两者结合检查诊断的灵敏性、特异性和准确性明显高于单一的CT、MRI检查(P<0.05)。结论CT检查结合MRI检查对小儿炎性肌纤维母细胞瘤的诊断效果更好,能为临床诊断提供更多影像学信息。

Objective To investigate the diagnostic effect of CT combined with MRI on inflammatory myofibroblastic tumor in children.Methods The clinical data of 30 children with inflammatory myofibroblastic tumor admitted to our hospital from July 2017 to May 2019 were analyzed retrospectively.All patients underwent CT examination and MRI examination.The characteristics of the images were analyzed,and the diagnostic accuracy,sensitivity and specificity of CT examination,MRI examination and combined examination of them for inflammatory fibroblastoma in children were compared.Results The sensitivity,specificity and accuracy of CT examination for pediatric inflammatory myofibroblastic tumor were 76.66%,66.66%and 83.33%,respectively.The sensitivity,specificity and accuracy of MRI examination were 83.33%,80.00%and 90.00%,respectively.The sensitivity,specificity and accuracy of CT examination combined with MRI for pediatric inflammatory myofibroblastic tumor were 93.33%,96.66%,and 96.66%,respectively.The sensitivity,specificity and accuracy of MRI examination for pediatric inflammatory myofibroblastic tumor were higher than those of CT examination.However,the diagnostic sensitivity,specificity and accuracy of the combined examination were significantly higher than those of the single CT and MRI(P<0.05).Conclusion CT examination combined with MRI examination has a better diagnostic effect on inflammatory myofibroblastoma in children,and can provide more information for clinical diagnosis.
