Data analysis validation. Panel A: Image and line profile through the bottle on scans 1 (top) and 2 (middle), and the difference image (bottom) calculated according to Equation 3. Panel B: Data from a representative participant showing the effect of the dose correction on the PETWALK image using Equation 1 when applied to co-registered images in native subject space. The images were then warped to standard Montreal Neurological Institute (MNI) space Top: PETSTAND, middle – uncorrected PETWALK, bottom – corrected PETWALK. The color bar shows image intensity across the three images. Image courtesy of NeuroImage.

Can PET help diagnose neurosarcoidosis?
By Will Morton
FDG-PET imaging shows promise for use as a diagnostic criterion for neurosarcoidosis, with a recent case series illustrating the approach was effective when gold-standard approaches were not, according to a group of researchers in Berlin.
