For the last century, there has been great physiological interest in brain iron and its role in
brain function and disease. It is well known that iron accumulates in the brain for people with …

The appearance of intracranial hemorrhage at magnetic resonance (MR) imaging depends
primarily on the age of the hematoma and the type of MR contrast (ie, T1 or T2 weighted). As …

Background and Purpose—The authors present an overview of the current evidence and
management recommendations for evaluation and treatment of adults with acute ischemic …

Background Although the use of magnetic resonance imaging (MRI) for the diagnosis of
acute stroke is increasing, this method has not proved more effective than computed …

ContextNoncontrast computed tomography (CT) is the standard brain imaging study for the
initial evaluation of patients with acute stroke symptoms. Multimodal magnetic resonance …

Using a one‐dimensional rapid imaging technique, we have found that injection of
lanthanide chelates such as Gd (DTPA) 2− leads to a significant decrease (50%) in rat brain …

Worldwide, stroke is a leading cause of death and disability. Recombinant tissue
plasminogen activator (rtPA) was approved a decade ago for the treatment of acute ischemic …

In the investigation of ischemic stroke, conventional structural magnetic resonance (MR)
techniques (eg, T1-weighted imaging, T2-weighted imaging, and proton density-weighted …

Heterogeneity of magnetic susceptibility within brain tissues creates unique contrast
between gray and white matter in magnetic resonance phase images acquired by gradient …

Background and Purpose—Although modern multisequence stroke MRI protocols are an
emerging imaging routine for the diagnostic assessment of acute ischemic stroke, their …
