Evaluation of a Stroke Protocol Using Computed Tomography Angiography for the Evaluation of Acute Ischemic Stroke Patients

Jan 2017 DOI 10.14302/issn.2470-5020.jnrt-16-1415
Jon W. SchrockCorresponding author

Objectives: Computed tomography angiography (CTA) provides early assessment of cerebral vasculature in ED patients presenting with Acute Ischemic Stroke (AIS). Prior studies using 4 row detector CT scanners have suggested that results may be used to determine who receives thrombolytics (tPA). We sou…

A Comparative Evaluation of the Role of Cone Beam Computed Tomography (CBCT) Imaging and Orthopantomography (OPG) in Sinus Augmentation Procedures: An Original Study
