Understand the Problem

The question is asking which imaging test is most appropriate for a patient evaluated after experiencing acute left arm weakness. The question provides a medical context with details about the patient's background, symptoms, and previous medical assessments, suggesting that the answer lies in understanding medical imaging protocols.

More Information

Carotid duplex ultrasonography is often used as the initial imaging test for evaluating episodes of transient ischemic attacks or acute stroke-like symptoms due to its ability to assess carotid artery stenosis, which can cause such symptoms.

Tips

Common mistakes include choosing imaging that is more invasive or not directly related to the vascular assessment necessary in this scenario.
