Magnetic Resonance Imaging Technology DTI in Alzheimer's Disease and the Application of Mild Cognitive Impairment

Objective to application of magnetic resonance diffusion tensor imaging(coursing together tensor imaging, DTI) research and identification of alzheimer's disease and mild cognitive impairment in patients with cerebral white matter damage. Methodsfor 45 cases of alzheimer's disease(AD) and 45 cases of patients with mild cognitive impairment(MCI) in brain DTI scan, measure the area of the opposite sex(FA) and an average score value dispersion rate(mean diffusivity, MD) and the comparison. Resultscompared with MCI group, AD groups on both sides of the parahippocampal gyrus, sides on both sides of the pillow, on both sides of the longitudinal beam and cingulate FA values were significantly lower after, P0.05). Compared with MCI group, AD groups on both sides of the parahippocampal gyrus, sides on both sides of the pillow, on both sides of the longitudinal beam and the cingulate cortex, MD, of the rise, P0.05). ConclusionsonclusionsDTI technology can be sensitive to detect the AD patients with MCI patients of cerebral white matter structure difference, which can be used for identification of MCI and AD.
