Abstract

Until recently, the need for an acute diagnosis of acute cerebral ischemia in the absence of therapeutic tools has been debated. Recent pharmacologic advances have brought the development of potentially neuroprotective drugs; therefore neuroimaging methods are needed that permit an acute diagnosis. Indeed traditional imaging methods such as computed tomography, Magnetic Resonance Imaging (MRI), Positon Emission Tomography and Single Photon Emission Computed Tomography have all proven to sometimes give only subtle information or require important hardware resources. A new method, diffusion-weighted MRI, allows the very early detection of cerebral ischemia and therefore represents an important addition to the diagnostic possibilities in acute stroke therapy. This technique allows to measure the brownian motion of protons in tissues. A stroke, with restricted diffusion, is seen within minutes or hours of onset as a bright area. In order to prevent motion-induced artifacts, the development of fast imaging techniques allowing the acquisition of a complete image set in a very short time is of extreme importance. Techniques such as echo-planar imaging, or other fast imaging techniques now permit to obtain imaging data in a fraction of a second.
