Increased hippocampal blood volume, but not flow, in schizophrenia
Hemodynamic parameters (mean ± SD) for healthy controls and patients with schizophrenia generated from dynamic susceptibility contrast-(DSC)-MRI for the hippocampus. These values are averaged across hemisphere and slice along the long axis of the hippocampus. Fig. 4A illustrates increased hippocampal cerebral blood volume (CBV) in schizophrenia (one-tailed t-test, t(28) = 1.831, p = 0.039). Fig. 4B illustrates no group differences in hippocampal cerebral blood flow (CBF, one-tailed t-test, t(28) = −0.629, p = 0.28), and Fig. 4C illustrates no difference in hippocampal mean transit time (MTT) in schizophrenia (two-tailed t-test, t(28) = −1.230, p = 0.22). *p < 0.05.
