Magnetic resonance imaging (MR) of ischemic cerebrovascular events with standard T1-and
T2-weighted spin-echo techniques is widely employed. Standard MR demonstrates vascular …

Diffusion-weighted imaging (DWI) is a new magnetic resonance imaging technique that
detects the tiny random movements of water molecules (diffusion) in tissues. This technique …

Diffusion-weighted magnetic resonance imaging (DWI) can quantitatively display focal brain
abnormalities within minutes after the onset of ischemia. We performed the present study to …

T he imaging of acute ischemic stroke has pro-ceeded through two major advances over the
past two decades. The introduction of computed tomography (CT) in the 1970s allowed …

Rapid MRI of the molecular diffusion of water demonstrated cerebral infarcts in 32 patients.
We studied these patients at various times following the onset of ischemic symptoms and …

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

In this issue of Neurology, two articles describe how the additional information derived from
diffusionweighted MRI (DWI) influences clinical decisionmaking and management of acute …

D IFFUSION magnetic resonance imaging (MRI) conveys novel information on the state of
living tissue. Diffusion provides image contrast that is dependent on the molecular motion of …

Magnetic resonance (MR) diffusion imaging allows detection of cerebral ischemia within
minutes of onset, and the temporal evolution of diffusion characteristics enables …

We performed serial diffusion-weighted imaging (DWI) in a patient with right middle cerebral
arterial occlusion using 1.0 T MRI. The initial DWI demonstrated suppression of water …
