Abstract:

Objective To explore the effect of resting-state functional magnetic resonance imaging (rs-fMRI) on functional connectivity(FC) in liver cancer(LC) patients with depression. Methods Twenty-one LC patients with depression (depression group) and 27 LC patients without depression (non depression group) were treated with 1.5T MR scanner, and rs-fMRI was obtained. The difference of FC was compared between groups, then, the correlation between functional imaging index and Hamilton Depression Scale (HAMD) score was analyzed.Resultss The patients with liver cancer and depression showed significantly weakened FC in the default mode network (the precuneus, the hippocampus and the parahippocampal gyrus, the inferior parietal lobule), the executive network (the cingulate gyrus, the medial frontal gyrus, the superior / middle / inferior frontal gyrus), the sensorimotor network (cerebellum), the salience network (the left insular lobe) and the thalamic node brain interval. The functional connection between the default mode network (inferior parietal lobule) and the sensorimotor network (the left cerebellum) was significantly enhanced in patients with liver cancer and depression.Conclusion LC patients with depression showed the functional connectivity abnormalities in multiple depression-related brain regions, which may be related to the neuropathological mechanism.
