Imaging in acute stroke

Show Summary Details

Preview

• CT scan of the brain performed in an emergency setting accurately identifies most cases of intracranial haemorrhage. • Diffusion-weighted MRI allows visualization of ischaemic lesions at very early time points and supplies information concerning lesion size, site, acuity as well as the possible aetiology. • A variety of modern MRI and ultrasound techniques can be used to further study tissue and vascular abnormalities in ischaemic stroke. • Several diagnostic tests should be performed routinely in patients with suspected ischaemic stroke to identify systemic conditions that may mimic or cause stroke or that may influence therapeutic options.
