Abstract:
Objective The aim of this study was to evaluate the glioma using the variety of functional magnetic resonance imaging( fMRI) ,and to perform a more accurate preoperative diagnosis of gliomas. Methods Thirty - five patients with gliomas confirmed by pathology were examined by magnetic resonance imaging (MRI)and functional MRI. Rapid diffusion coefficient(D?),Slow diffusion coefficient(D),perfusion fraction ( f) and distribution diffusion coefficient ( DDC ) in the intravoxel incoherent motion diffusion weighted imaging (IVIM-DWI) were analyzed statistically. Results The mean values of D?,D,f and DDC in the IVIM se-quence of the patients with high-grade of gliomas were statistically significant when compared to the IVIM values of the contralateral normal brain tissues(P<0. 05). Conclusion A variety of magnetic resonance functional im-aging sequences are used to analyze gliomas,which can avoid tumor heterogeneity and improve the recognition a-bility and accuracy of magnetic resonance imaging in high grade gliomas.
