Abstract：To investigate the value of DTI in brain tumor classification,the relationship between the DTI quantitative parameters and the level of brain tumor was studied by analysing the parameter values of FA and ADC,which can provide information for clinical application.19 cases confirmed by pathology of tumor patients of different levels were divided into different groups according to the grades of tumor,the differences of the tumor nature area and the contralateral normal area were compared by using matching t test about FA and ADC values,the differences of the high and low level of brain tumors were analyzed by using independent sample t test about FA and ADC values.There were significant differences in FA and ADC values between the tumor nature area and the contralateral nor-mal brain tissue of brain tumor patients.The ADC values of low levels of brain tumors were lower than that of high levels,and the differences were significant.Using FA and ADC values of brain tumor real area is helpful for distinguishing brain tumor areas and nor-mal brain tissue,but whether it is effective for brain tumor classification remains to be confirmed.The conjoint analysis method of mul-timodal images will become a new hot spot of noninvasive brain tumor classification.
