全身骨显像与CT对儿童神经母细胞瘤骨转移的诊断价值

摘要

目的:比较全身骨显像及CT对儿童神经母细胞瘤骨转移的诊断价值.方法:选取经病理、影像学检查或临床随访等证实合并有骨转移的56例神经母细胞瘤患儿,比较全身骨显像及CT诊断神经母细胞瘤骨转移的阳性率.结果:全身骨显像与CT诊断神经母细胞瘤患儿骨转移一致性差(kappa=0.231,P=0.007);全身骨显像与CT诊断骨转移阳性率分别为91.1%和57.1%.结论:两种方法均可诊断神经母细胞瘤骨转移,但全身骨显像的诊断效能优于CT.%Aim: To compare the value of whole body bone scan ( WBS) and CT in diagnosing bone metastases of neuroblastoma in children. Methods: A total of 56 children who were formerly confirmed as bone metastasis by pathology , video-imaging or clinical follow-up, performed WBS and CT,respectively. The positive rate of the two methods in diagnosing bone metastases of neuroblastoma was compared. Results: Consistency of WBS and CT in diagnosing bone metastasis of neuroblastoma was poor ( kappa = 0. 231 , P = 0. 007 ) , and the positive rate was 91.1% and 57. 1% , respectively. Conclusion: Bone metastasis of neuroblastoma can be diagnosed by both WBS and CT ; diagnostic efficiency of WBS is higher than CT.
