Proton MRS in Behçet's disease with and without neurological findings.
Our aim was to investigate whether neurological impairment in Behçet's disease (BD) can be assessed by means of proton MRS and whether it can assist in prognosis. We used single-voxel MRS to measure metabolites in regions of normal-appearing pons, basal ganglia and periventricular white matter (PWM) in 32 patients with chronic BD patients with and without neurological deficits and 29 control subjects. Patients had significantly higher N-acetylaspartate (NAA)/creatine (Cr) and choline (Cho)/Cr ratios in the basal ganglia than the controls. The Cho/Cr ratio in the PWM was also significantly higher in the patients. MRS enabled clear discrimination of patients and controls and also revealed spectral differences between non-neuro-Behçet's disease and neuro-Behçet's disease in the basal ganglia. MRS can be used to assess brain involvement in BD even if structural changes are absent.
