Figure 2From: Enhanced catecholamine transporter binding in the locus coeruleus of patients with early Parkinson disease Scatter plots and linear correlations of ipsilateral (left in the figure) and contralateral (right in the figure) FP-CIT binding values of the locus coeruleus and striatum (caudate nucleus and putamen). A statistically significant negative correlation was found between FP-CIT binding values in the locus coeruleus area and the corresponding striatum (both caudate nucleus and putamen).Back to article page
