Yield of Computed Tomography (CT) Angiography in Patients with Acute Headache, Normal Neurological Examination, and Normal Non Contrast CT: A Meta-Analysis

Computed tomography angiography (CTA) is used increasingly in the emergency department for evaluating this, but its added value remains controversial.
