Abstract

OBJECTIVE. The purpose of this article is to discuss how a unilateral fetal posterior cerebral artery (PCA) causes perfusion map asymmetry due to anteroposterior bolus arrival discrepancy. We performed region of interest analysis of asymmetric perfusion maps before and after delay correction was performed. CONCLUSION. Perfusion asymmetry becomes unapparent using a delay correction algorithm, indicating bolus arrival delay on the side opposite the fetal PCA. Delay correction algorithms can eliminate deconvolution errors related to bolus arrival delay.
