Abstract
The prelims comprise: ct angiography (cta) is commonly used as a first vascular diagnostic tool in emergency situations, such as acute stroke and subarachnoid hemorrhage it is a fast and safe exam, but requires post-processing and skill to interpret cta is as sensitive and specific as digital subtraction angiography for diagnosis of intracranial aneurysms, to a cutoff of 3mm size. cta can help in decisions to treat acute stroke endovascularly, whenever a large vessel occlusion is found. ctv is diagnostic for cerebral sinus thrombosis, but not as specific as mrv for cerebral vein thrombosis metallic artifacts, such as coils and aneurysm clips can be a problem for image interpretation
