Fig. 1From: No significant difference found in PET/MRI CBF values reconstructed with CT-atlas-based and ZTE MR attenuation correctionROIs on several representative slices of MRI (left two columns) and PET (right two columns). Different colors shows different locations of frontal (red), temporal (cyan), occipital (light pink), parietal (blue) lobes, basal ganglia (green), thalamus (yellow), and cerebellum (orange). ROIs were placed in the MRI images and transferred to the CBF-PET in the same locationBack to article page
