Table 1 Spearman correlation and linear regression analysis between SRTM BP values for the right striatum at different time points after LPS injection using a 90- and 120-min acquisition time interval, comparing BP_L STR using the left striatum as reference region with BP_wlow using all brain regions weighted with the corresponding SVCA3 w_low weights to generate a virtual pseudo-reference region and with BP_low using brain regions with corresponding SVCA3 w_low weights greater than 0.95 to define a composite pseudo-reference region
