RESUMO

Objective To study the characteristics of diffusion tensor imaging (DTI) in brain tumor and it's diagnosis and differential diagnosis value.Methods Thirty-nine patients with brain tumors proven by pathologically (10 meningioma,17 glioma,12 metastatic tumors) were enrolled,by using Philips Achieva 1.5 T MRI,conventional MRI and DTI were underwent on them,fractional anisotropy (FA) maps,apparent diffusion coefficient (ADC) maps and three dimensional white matter fiber bundle map were reconstructed in the workstation.The core substance of the tumor area and the contralateral mirror area were selected as the region of interest,and FA and ADC values of them were measured,and t test was performed.Results The FA values of meningioma,metastases tumors and gliomas were 0.36 ± 0.08,0.28 ± 0.03,0.18 ± 0.06,respectively,and the differences among them were significant( P < 0.05).The ADC values of meningioma,metastases tumors and gliomas were 1.72 ± 0.10,1.52 ± 0.22,1.34 ± 0.14,respectively,and the differences among them were significant( P < 0.05).Conclusion DTI has high clinical value in identification of meningiomas,metastatic tumors and glioma.
