Fig. 1From: Brain magnetic resonance spectroscopy and cognitive impairment in chronic hepatitis C patientsMRS at basal ganglia in patients with cognitive impairment. Spectroscopic voxel of interest were done at basal ganglia in sagittal, coronal, and axial plans in patients with impaired attention/concentration/psychomotor score. Curve showed that NAA/Cr ratio was elevated (R = 0.499 and p value = 0.026), and CHO/Cr ratio was reduced (R = − 0.630 and p value = 0.008)Back to article page
