Results of the FDG-PET study in single patient generated automatically by the CORTEX ID software. Standard Uptake Value (SUV) and z-score maps presented as three-dimensional Stereotactic Surface Projection (3D-SSP) images of the brain cortex and a table of parametrical values of z-scores for different cortical locations. SUV maps show an absolute glucose metabolism with the red color indicating a high glucose metabolism (hypermetabolism), green color a normal glucose metabolism and in blue color a decreased glucose metabolism (hypometablism). Z-score maps show a cerebral glucose metabolism in relation to the rate of the glucose metabolism of the control group; on z-score maps red color indicates severe hypometabolism, green intermediate hypometabolism and blue color a normal glucose metabolism
