Sensitivity and Specificity of the Hyperdense Artery Sign for Arterial Obstruction in Acute Ischemic Stroke [Clinical Sciences]

Thin-slice CT improves sensitivity of HAS detection. Clinical Trial Registration— URL: http://www.controlled-trials.com/ISRCTN25765518. Unique identifier: ISRCTN25765518.
