Episode 71 – Chicken, Starfish & Cat Scans

 

Due to the popularity of Episode 68 – X-Ray Vision, we’ve decided to extend our radiology series and focus on computerized tomography (CT) scans. Head CT scans, specifically, are often viewed by emergency and transport clinicians when patients require tertiary neurovascular services. Tune in to another visually-guided episode as we discuss this extremely important topic, providing ways to easily interpret the various forms of intracranial hemorrhages with some additional findings that you may encounter.
