This article focuses on clinical applications of arterial spin labeling (ASL) and is part of a
wider effort from the International Society for Magnetic Resonance in Medicine (ISMRM) …

Stroke mimics constitute a significant proportion of patients with suspected acute ischemic
stroke. These conditions may resemble acute ischemic stroke and demonstrate …

The main arteries that supply blood to the brain originate from the Circle of Willis (CoW). The
CoW exhibits considerable anatomical variations which may have clinical importance, but …

Background. The unilateral fetal variant of the posterior cerebral artery (FPCA) is
characterized by the congenital absence of the P1 arterial segment. The artery of Percheron …

Abstract Background and Objectives Clinical diagnosis of ischemic stroke commonly relies
on examining cerebral perfusion changes by using computed tomography perfusion (CTP) …

Background and Objectives: Intracranial hemorrhage caused by the rupture of brain
aneurysms occurs in almost 10 per 100,000 people whereas the incidence of such …

The circle of Willis (CoW) is a critical, arterial structure that ensures balanced, cerebral-blood
supply. The fetal-type posterior cerebral artery (f-PCA) is a CoW variant that can significantly …

The generalization of perfusion-based, anterior circulation large vessel occlusion selection
criteria to posterior circulation stroke is not straightforward due to physiologic delay, which …

Clinical interpretation of arterial spin labeling (ASL) perfusion MRI in cerebrovascular
disease remains challenging mainly because of the method's sensitivity to concomitant …

Magnetic resonance imaging perfusion (MRP) techniques can improve the selection of
acute ischemic stroke patients for treatment by estimating the salvageable area of …
