The development of new therapies for treating the acute stroke patient has produced
demands for sophisticated imaging and physiologic evaluation, as demonstrated in the …

During the past few years, there has been increasing interest in magnetic resonance
imaging (MRI) of acute stroke. MRI is now competing with computed tomography (CT), which …

Stroke remains a major health care challenge worldwide and is the second leading cause of
death and the leading cause of disability in Western countries. Ischemic stroke represents …

When magnetic resonance (MR) imaging–based techniques for studying brain perfusion
were developed in the 1980s and 1990s, 1 one of the first pathologic conditions to which …

With the advances in new neuroimaging modalities, the role of imaging of acute ischemic
