Hypometabolic artifacts observed in patient group using SPM-A and SPM-P analysis. Hypometabolic artifacts observed in patient group (n = 47) using SPM-A analysis (adult control group) and SPM-P analysis (pediatric pseudo-control group). X axis presents the ages (in years). Y axis presents the number of hypometabolic artifacts (false positive results) using SPM-A (lozenges) and SPM-P (circles) analysis. The broken line represents the number of patients at the different ages. Notice that artifacts are observed less frequently using SPM-P than SPM-A, and none was found in patients under 6 years old using SPM-P.
