Table 3 Comparison of quantitative values of ^99mT_c uptake in TRODAT-SPECT. The uptake is in the whole striatum, putamen, caudate and occipital in the form of whole striatum binding ratios, putamen binding ratio, and caudate binding ratio between the Parkinson’s disease patient and healthy age-matched controls
