CBF (a), OEF (b), CMRO2 (c), and CBV (d) of each brain region according to each reconstruction method. The quantitative values obtained using each reconstruction were compared using a paired t test with Bonferroni’s correction (*P < 0.05, **P < 0.01). In the whole brain, OSEM3D-MAP revealed a 20% increase in CBF and a 15% increase in CMRO2, compared with the FBP findings, which resulted in a 5% decrease in the OEF. The differences in CBV among the three reconstruction methods were relatively small
