Technique d'exploration des vaisseaux cervicaux et encéphaliques : angioscanner

Examination of acute stroke by CT angiography is an alternative to MRI. Technological improvement of multidetector CT scanners allows neuroimaging of stroke in a multimodal protocol including plain CT, cerebral CT perfusion and CT angiography of the cervical and intracranial arteries. CT angiography is a reliable non invasive technique for the evaluation both extracranial and intracranial vessels that may be used as an alternative to MR angiography.
