Objective: To analyze the application of functional magnetic resonance imaging in the study of brain function and structure in elderly patients with depression. METHODS: A total of 52 elderly patients with depression were enrolled in our hospital as the observation group. A total of 52 normal elderly patients who received a physical examination in our hospital were selected as the control group. The admission time of all subjects was 2018. From May to May 2019, all testers used high-resolution structural images and functional scans under NMR to scan the image results; the comfort of all subjects was compared. RESULTS: The score of the depression scale of the observation group was (12.76±4.17), which was higher than that of the control group (1.18±0.44). The score of the mental state examination scale of the observation group was (26.9±2.58), slightly lower than There were no significant differences in the control group (29.1±2.05) points; the central side lobules, the middle left fusiform gyrus, the central posterior gyrus, the superior temporal gyrus, the inferior parietal lobes and the anterior cranial lobes, and the forehead The Reho of the right occipital mid-back and the lower abdomen were significantly lower than the control group (P<0.05). The wedges of the observation group, the left inferior temporal gyrus, the inferior temporal gyrus, the inferior frontal gyrus, and the shuttle were observed. The GMV levels in the anterior gyrus, anterior wedge and medial cingulate gyrus were significantly lower than those in the control group (P<0.05). Conclusion: Abnormal brain function and structure of elderly subjects have no effect on the neuropathological mechanism of depression. They are independent of each other. Through analysis of the images, it is found that the brain region of the subject is functional and abnormal. There is no overlap.
