Using single-photon emission computed tomography (SPECT) scanning, Tutus et al reported significant differences between the perfusion index values of untreated adolescents with depression and those of control patients. The researchers found that adolescents with major depressive disorder may have regional blood flow deficits in the left anterofrontal and left temporal cortical regions, with greater right-left perfusion asymmetry than healthy control patients.
