Abstract : Arterial Spin Labeling (ASL) is prone to a number of artifacts, which may affect its diagnostic accuracy. To avoid these pitfalls, possible effects on the ASL measurements should be identified. Perfusion asymmetry in the posterior cerebral artery (PCA) territory may be induced by the fetal-type PCA. Whenever a posterior left-right asymmetry is observed on the ASL, structural MR images should be taken into account to rule out cerebrovascular pathology mimickers such as unilateral fetal-type PCA.
