title: [Neuroradiological focus on stroke imaging].
abstract: Stroke is heterogenous in its symptoms, which are also caused by various pathologies. Clinically the causing mechanism (bleeding or ischemia) of a new onset of neurological deficits can not reliably be distinguished. However, ischemia is four times more frequent than a bleeding causing neurological symptoms. Modern imaging technologies (computed assisted tomography or magnetic resonace imaging) and interventional techniques are a mainstay in diagnostics and management of acute onset of neurological symptoms. They can reliably distinguish between bleeding and stroke, especially taking newest technologies, such as perfusion studies and angiographies, into account. Neuroradiology with its interventional options has nowadays furthermore become an important tool in strokes and offers a local maneuver to retrieve the clotting pathology and even opens the therapeutic window for a delayed start of the therapy since symptom's onset beyong the conventional 4.5 hours window. Also risks of a therapy and which therapy option should be used can immediately be assessed.
