Grand Rounds - Acute Stroke Neuroimaging - Internal TS Lecture
Recognition of a large vessel occlusion using CT angiography has become essential in identifying patients for endovascular thrombectomy. Techniques such as imaging collaterals on CT angiography or measuring blood flow to predict tissue fate using CT perfusion have become useful tools in selecting patients for acute stroke therapy. Neurologists' level of comfort in interpretation of advanced imaging varies. The goal of this presentation is to improve interpretation of CT head (including ASPECTs score), CT angiography of the head and neck and CT perfusion, and to improve timely stroke triaging.
Learners will be able to
- review CT angiography and identify large vessel occlusion
- interpret CTP, especially pneumbra versus core infarct
- interpret ASPECTs scoring of CT head
