ABSTRACT
Objective:
To clarify the significance of the fractional anisotropy(FA) value and apparent diffusion coefficient(ADC) value of diffusion tensor imaging(DTI) applied in the glioma grading with Meta-analysis, and to provide a reference for selecting the treatment program and judging the prognosis of glioma.Methods:
Computer search was performed in PubMed database, EMBASE database,CBM, CNKI, Wanfang database, and VIP database.The relevant neurosurgery magazines and neuroimaging magazines, the proceedings of academic meeting were retrieved by hand and the references of related reviews were retrospectively retrieved.Then the case-series studies according to inclusion and exclusion criteria were screened,and the qualities of included studies were evaluated.Meta-analysis was carried out by Review Manager 5.2 software.Results:
Nine studies were included.The FA value of low-grade glioma(LGG) in tumor centre was lower than that of high-grade glioma(HGG) (χ2=11.94,df=8,P=0.15;I2=33%,Z=2.78,P=0.005;WMDFA=-0.02,95%CI-0.03--0.01),and the ADC value of LGG in tumor centre was higher than that of HGG (χ2=5.26,df=4,P=0.26;I2=24%,Z=2.19,P=0.03;WMDADC=0.15,95%CI0.02-0.28).Conclusion:
When the FA value in tumor centre of the glioma is increasd,the ADC value is decreased,and the grade of glioma is increasd.The FA value and ADC value of DTI can help determine the grade of gliomas.
