[1H-MRS of the hippocampus of psychogenic erectile dysfunction].
To study the changes of the hippocampus metabolites with MRS to provide some clues for exploring the possible underlying unrecognised factors and pathophysiological mechanisms of psychogenic erectile dysfunction (ED).. Fifteen cases of psychogenic erectile dysfunction and 15 normal volunteers (the control) were studied by a clinical 1. 5T MRI/MRS system. Proton multi-voxel spectroscopy imaging (1H-MRSI) was obtained from both sides of the hippocampus region. N-acetylaspartate (NAA), creatine and phosphocreatine (Cr) and choline-containing compounds (Cho) were determined and the ratios of NAA/Cr and Cho/Cr were calculated respectively.. The NAA/Cr ratio was significantly lower in the ED patients than in the control (P < 0.05). There was no significant difference in the Cho/Cr ratio between the two groups (P > 0.05).. Psychogenic erectile dysfunction may not be simply a functional disease. The hippocampus may be involved in the pathophysiology of psychogenic ED. The disease may have some previously unrecognised underlying aetiological factors and pathophysiological mechanisms.
