Table 2.

Visual and automatic SBR-based categorization of the DAT-SPECT images. With-versus-without-ASC cross table of the visual categorization of the DAT-SPECT images according to the majority of the three readers (intra-reader consensus) (top) and of the automatic categorization of the DAT-SPECT images based on the putamen SBR using the cutoff derived from the histogram analysis (Table 3). Given are the number and percentage of the cases (n = 1740)
