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 3

Representative cases of a healthy control and a PD patient with their []-TRODAT images aligned with the inversely transformed predefined VOIs for the striatum and the reference region. This figure shows the transverse and coronal views of the original images, the images fused with the reference VOI, and the images fused with the striatal VOI. Through visual interpretation, proper alignment of both VOIs was confirmed and demonstrated.
