Preliminary Study of Diffusion Tensor Imaging in Differentiating Diagnosis of High-grade Gliomas and Metastatic Tumors

Objective To evaluate the role of diffusion tensor imaging in differentiating of intracranial tumors primarily. Methods Eight patients with high-grade cerebral gliomas and six patients with metastatic tumors underwent conventional MRI and diffusion tensor MR imaging before therapy. ADC and FA were measured in each region of interest(ROI), caculatated the ratio to the contralateral corresponding ROI, then make statistical analysis. Results The ADC ratio and FA ratio of white matter surrounding the edema of...
