Fig. 4From: Stereotactical normalization with multiple templates representative of normal and Parkinson-typical reduction of striatal uptake improves the discriminative power of automatic semi-quantitative analysis in dopamine transporter SPECTScatter plots of the putamen SBR versus the amount of stretching by stereotactical normalization. The scatter plots of the minimum putamen SBR from hottest voxels analysis versus the DET of the affine transformation for stereotactical normalization are shown separately for single (left) and multiple (right) templates. The dashed lines indicate the result of linear regression, separately for normal and reduced SBRBack to article page
