Abstract:
Objective:To analyze the imaging changes of patients with monophasic depression based on the changes in CT parameters of each cerebral lobe.Methods:A total of 100 patients with monophasic depression who received treatment in Department of Radiology, Shaoxing 7 th People's Hospital between June 2019 and June 2021 were included in the observation group. An additional 100 healthy individuals who concurrently received physical examination were included in the control group. CT scan of the brain was performed in all participants. CT value of each cerebral lobe was compared between the two groups. Results:CT values of the left frontal lobe and left temporal lobe in the observation group were (40.88 ± 2.01) HU and (40.21 ± 3.01) HU, respectively, which were significantly lower than those in the control group ( tleft frontal lobe = 2.94, P = 0.004; tleft temporal lobe = 3.29, P = 0.001). CT values of the right frontal lobe and right temporal lobe in the observation group were (40.09 ± 2.52) HU and (44.93 ± 3.03) HU, respectively. There were no significant differences in CT values of the right frontal lobe and right temporal lobe between the two groups ( tright frontal lobe = 1.89, P = 0.060; tright temporal lobe = 1.89, P = 0.060). There were no significant differences in CT values of the left and right occipital lobes and the left and right parietal lobes between the two groups (all P > 0.05). One-way analysis of variance revealed that the CT values of the left and right frontal lobes were negatively correlated with age (-0.441, -0.211) and course of disease (-0.445, -0.191) (both P < 0.05); the CT values of the left and right frontal lobes were not significantly correlated with 24-item Hamilton Depression Rating Scale score and the number of attacks (all P > 0.05). The CT values of the left and right temporal lobes (-0.207, -0.213), the left and right occipital lobes (-0.185, -0.195) and the left and right parietal lobes (-0.185, -0.180) were negatively correlated with age (all P < 0.05). The CT values of the left and right temporal lobes, the left and right occipital lobes, and the left and right parietal lobes were not significantly correlated with course of disease, 24-item Hamilton Depression Rating Scale score, and the number of attacks (all P > 0.05). Conclusion:The left and right frontal lobe and the left temporal lobe are atrophic in patients with monophasic depression. The degree of atrophy is closely related to the course of disease. Therefore, these findings can be used as a reference for imaging diagnosis of degenerative diseases of the central nervous system.
