Fig. 2From: 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 SPECTHistograms of the putamen SBR. The histograms represent the 1702 DAT-SPECT with proper stereotactical normalization according to visual inspection, separately for the different settings. The fit by the sum of two Gaussians is indicated by a continuous line. The effect size d of the distance between the two Gaussian functions was computed according to Eq. (2)Back to article page
