Fig. 9From: Cross-validation study between the HRRT and the PET component of the SIGNA PET/MRI system with focus on neuroimagingBPND of [11C]DTBZ (a) and [11C]raclopride (e) scans and ratios to reference region for [18F]FDG (c) scans. Calculated ratios of HRRT to PET/MR scans are depicted for [11C]DTBZ (b), [18F]FDG (d), and [11C]raclopride (f). Mean ratios of HRRT to PET/MR values for each tracer are depicted in (g). Dotted red line represents the ratio of 1Back to article page
