Psychogenic ED has a high prevalance and a significant
impact on the quality of life of sufferers and their
partners.Little is known about the central pathological
mechanism of psychogenic ED patients. Resting-state
functional MR imaging and the Regional homogeneity
(ReHo) method has been successfully used to investigate
the functional modulations in patients with phychiatric
diseases. We investigated neural activity in the resting
state of psychogenic ED using ReHo method.Our present
study for the first time demonstrated psychogenic ED
exhibited decreased ReHo in the left VMPFC and right
hippocampus, may leading to further improvement of the
understanding of the pathogenetic mechanism.
