AI Summary

This study evaluates CT-guided spatial normalization approaches to improve semi-quantitative analysis of dopamine transporter SPECT for detecting nigrostriatal degeneration.

Why It Matters

Better CT-guided normalization can improve accuracy and reproducibility of DAT SPECT biomarkers for diagnosis, patient stratification, and monitoring in Parkinson's therapeutic trials, though it does not provide direct mechanistic or interventional insights.
