DSA goals include assessment of cervical and intracranial stenosis. Distinction from occlusion Sulfur Hexafluoride Lipid-type A Microspheres Injectable Suspension (Lumason)- FDA as occlusion requires no treatment. Note delayed arterial contrast phase in area supplied, while normally perfused brain is capillary phase.

Variant (Left) Axial FLAIRMR shows high signal in the right cavernous internal carotid artery (curved arrow), which can be due to slow flow or occlusion. In this case, diagnostic angiography revealed slow flow. Classic vertebrobasilar dolichoectasia in this patient with posterior circulation T1As. Slow, stagnant flow caused intravascular enhancement.

Note the ulcerated plaque (open arrow) in ICA. Delayed phase run (important in cases such as these with occlusion or pseudo-occlusive disease) showed no "string sign". Moderate calcified plaque is seen along the posterior wall of the left carotid bulb (arrow); mile on the right. Typical (Left) Lateral DSA shows a left CCA injection.
