Intracranial TOF-MRA for estimation of extracranial proximal artery stenosis

Essential for the prognosis of patients with acute ischemic stroke is a fast admission to therapeutic approaches like intravenous or intraarterial fibrinolysis. In the latter beside the precise localization and size of an ischemia especially possible obstacles in the access to an occluded vessel are important to know for optimal treatment. Moreover even in intravenous fibrinolysis the effectiveness of thrombolysis seems to decrease with the existence of an additional extracranial artery stenosis. MRI-protocols including DWI-PWI-imaging may allow tailor-made treatment within minutes. One part of most stroke routi…
