BACKGROUND AND PURPOSE: Diffusion-weighted MR imaging is generally
acknowledged to be more sensitive in detecting acute stroke than is conventional MR …

The purpose of this study was to evaluate the time course of arterial hyperintensity (AH) in
acute and subacute cerebral infarctions of the middle cerebral artery (MCA) distribution by …

BACKGROUND AND PURPOSE: Fluid-attenuated inversion recovery (FLAIR) vascular
hyperintensities (FVH) are commonly encountered on MR imaging studies performed shortly …

Objective: To describe hyperintense vessels sign (HVS) in patients with acute stroke on fluid-
attenuated inversion recovery (FLAIR) MRI and determine its clinical significance and utility …

Background and Purpose—Hyperintense vessels (HVs) have been observed in fluid-
attenuated inversion recovery imaging of patients with acute ischemic stroke and been …

Purpose: To prospectively determine which diffusion-weighted magnetic resonance (MR)
imaging technique (ie, conventional diffusion-weighted MR imaging [b= 1000 or 1500 …

BACKGROUND AND PURPOSE: Recent technological advances in MR instrumentation
allow acquisition of whole-brain diffusion-weighted MR scans to be obtained with b values …

However, FLAIR MR images show intraarterial thrombus or slow arterial flow more clearly as
a hyperintense vessel surrounded by hypointense cerebrospinal fluid [3]. In particular, the …

BACKGROUND AND PURPOSE: Previous acute stroke studies found diffusion-weighted
(DW) imaging superior to CT for detection of early ischemic signs (EIS). However, these …

BACKGROUND AND PURPOSE: Echo-planar diffusion-weighted and fluid-attenuated
inversion-recovery (FLAIR) imaging have both proved valuable for detecting acute ischemic …
