Fig. 4From: Harmonization of brain PET images in multi-center PET studies using Hoffman phantom scanComparing GMRC and contrast for A, C non-eroded and B, D eroded VOIs as a function of COV% for harmonized versus non-harmonized PET images. Panels E, F display left-to-right hemisphere RC ratios and cold-spot RC of different reconstructions for harmonized vs. non-harmonized imagesBack to article page
