Fig. 2From: No significant difference found in PET/MRI CBF values reconstructed with CT-atlas-based and ZTE MR attenuation correctionMRAC maps from the AB- (a) and ZTE-based (c) methods, and ZTE images (b) for PET attenuation correction. Although the ZTE-MRAC shows similar head AC maps to AB-MRAC, there are slight differences in the frontal sinus region (left column of axial sections) and bone thickness in the parietal region (middle and right column of axial sections)Back to article page
