Fig. 2From: Oxygen extraction fraction is not uniform in human brain: a positron emission tomography studyAveraged anatomically standardized PET images with attenuation correction by DIXONbone. Scale maximum values are 50 mL/100 mL/min, 12 mL/100 mL, 0.6, and 4 mL/100 mL/min for CBF, CBV, OEF, and CMRO2 images, respectively. The image slices are the same as Fig. 3Back to article page
