Development of AI-based dopamine transporter (DAT) image generation technique using early phase [18F]-FP-CIT PET imaging
Fig 5
Scatter plots showing the correlation between SNBR from generated and real delayed-phase PET images in the independent validation set.
The SNBR of the whole striatum exhibited a high correlation, with an R-value of 0.90. Subregional SNBRs exhibited high correlations, ranging from 0.84 for the CA to 0.92 for the PP. Abbreviations: SNBR, specific to non-specific binding ratio; PET, positron emission tomography; PP, posterior putamen. CA, caudate nucleus.
