The effect of field strengths of the total cerebral blood flow (TCBF) quantification using non-gated phase contrast magnetic resonance imaging (PC-MRI) was evaluated in this study. Our results show that, non-gated PC-MRI for TCBF quantification at 3T provided better inter-scan reproducibility when compared to that at 1.5T. Nevertheless, non-gated PC-MRI for TCBF measurements can be performed equally well at 1.5T and 3T. Findings of this study may facilitate data interpretation and comparison of TCBF between different field strengths.
