Fully Automated Quantification of the Striatal Uptake Ratio of [^99mTc]-TRODAT with SPECT Imaging: Evaluation of the Diagnostic Performance in Parkinson’s Disease and the Temporal Regression of Striatal Tracer Uptake

Figure 4

The ROC curve for the differentiation of the PD subjects () from the nPD subjects (). The area under curve (AUC) was 0.94 for this ROC curve, which indicates an excellent diagnostic performance based on the fully automatic SRR quantification proposed in this report.
