Imaging of Posterior Circulation Stroke - Basilar artery thrombosis and beyond (improved sound)

(New version with better sound quality) Previous presentations on this channel on the topic of stroke mainly focussed on acute ischemic stroke in the anterior circulation. In this presentation I'll specifically discuss posterior circulation stroke. The role of imaging in posterior circulation stroke cannot be underestimated (well, it can never be underestimated whatever the indication off course :)) because these strokes can present with generalized non-focal symptoms and index of clinical (and radiological) suspicion can be low. Nevertheless, they are associated with considerable morbidity and mortality. 0:00 - Topics 1:21 - Introduction 6:10 - Vascular Anatomy and vascular variants 22:32 - Imaging of posterior circulation stroke 22:47 - CT in posterior circulation stroke 26:32 - Perfusion-CT 31:35 - CT-angiography 37:35 - MRI in posterior circulation stroke 38:33 - Territorial stroke patterns 42:38 - Lacunar stroke patterns 48:25 - Artery of Percheron infarction 52:24 - Silent cerebellar infarctions 53:55 - Summary and key messages This video is brought to you by the neuroradiologist:   / theneuroradguy     / the_neurora.  . https://theneuroradiologist.org/ #radiology #neuroradiology #neurology #medicalstudent #neuroradiologist #theneuroradiologist #stroke #stroketreatment #interventionalradiology #MRI #medical
