Abstract:
Objective:To compare the diagnostic value of MRI and CT in neuroblastoma of central nervous system.
Methods:The clinical and imaging data of 40 patients with highly suspected neuroblastoma of the central nervous system admitted to the Traditional Chinese Medicine Hospital of Putuo District from January 2013 to January 2018 were retrospectively analyzed.According to the imaging examination methods, they were divided into MRI group(22 cases) and CT group(18 cases).
Results:A total of 19 cases of neuroblastoma of central nervous system were confirmed by pathology and 16 cases by CT after operation in the group of MRI.The accuracy, sensitivity and specificity of MRI and CT in the diagnosis of neuroblastoma of central nervous system were 86.36%(19/22), 88.89%(16/18), 89.47%(17/19), 87.50%(14/16), 66.67%(2/3) and 50.00%(1/2), respectively.The accuracy, sensitivity and specificity between the two groups had no statistically significant differences(all P>0.05). The solid part of the tumors showed equal or slightly longer T1WI and T2WI signals, while the FLAIR sequence was mainly equal signal.The cystic part showed long T1WI and T2WI signals, while the low FLAIR sequence signals.The tumors had clear margins and slight edema around the tumors.CT showed that the solid part of the tumors was homogeneous or slightly high density, with calcification and cystic part showing homogeneous low density.
Conclusion:Both MRI and CT are of high accuracy in the diagnosis of neuroblastoma of the central nervous system, and there are some similarities between them.
