In this multisite ASL study, we used a standardized FAIR protocol to measure baseline CBF in 112 healthy controls and gender/age matched 122 schizophrenic patients across 6 sites. CBF processing and group analysis were performed by the CBFBIRN Data Analysis and Processing Pipeline (https://cbfbirn.ucsd.edu). Whole-brain gray matter CBF was significantly lower in patients (52.031.36 ml/100g-min) compared to healthy controls (55.121.36 ml/100g-min). In standard space, voxel-level analysis, schizophrenia was associated with 12 brain regions characterized by hypoperfusion (p<0.01, corrected) including right insula. In contrast, CBF in right putamen was found to be higher with schizophrenia (41.271.72 vs. 34.271.62 ml/100g-min).
