Answer

Carotid duplex scanning is one of the most useful tests in evaluating patients with stroke. Increasingly, it is being performed earlier in the evaluation, not only to define the cause of the stroke but also to stratify patients for either medical management or carotid intervention if they have carotid stenoses.
