ADC值在鑒別間變型與非間變型室管膜瘤中的應用
[Abstract]:Objective: to evaluate the value of diffusion weighted imaging (DWI) and apparent coefficient diffusion (ADC) in differential diagnosis of intervariant and non-intervariant ependymoma. Methods: the data of 52 cases of ependymoma confirmed by operation and pathology in our hospital were retrospectively analyzed. Among them, 27 cases were non-anaplastic ependymoma and 25 cases were anaplastic ependymoma. The minimum, average and maximum ADC values of the tumor parenchyma were measured, and the diagnostic efficacy was analyzed by ROC curve. Results: the minimum ADC value of stromal ependymoma [(0.808 鹵0.190) 脳 10 ~ (-3) mm~2/s] was significantly lower than that of non-intervariant ependymoma [(1.093 鹵0.365) 脳 10 ~ (-3) mm~2/s] (P0.05). The best minimum ADC value for differentiating two kinds of tumors was 0.887 脳 10 ~ (-3) mm~2/s,. The diagnostic sensitivity was 78.5% and the specificity was 73.2%. There was no significant difference between the average ADC value and the maximum ADC value of the two types of tumors (P0.05). Conclusion: the minimum ADC value is helpful to the differential diagnosis of intermetamorphic ependymoma and non-anaplastic ependymoma.
