The purpose of this exhibit to review:  1. To present in an interactive manner a series of challenging cases to help improve the radiologist’s diagnostic accuracy and to provide clinical context for better reporting (i.e. 'what the clinician needs to know'). 2. To address common interpretive errors in an attempt to improve the diagnostic accuracy of the interpreting radiologist. 3. To review basic vascular anatomy, common anatomic variants and sites that are most likely to harbor missed vascular entities (i.e. 'blind spots’) and to present a comprehensive checklist that will help decrease the likelihood of interpretation errors at routine CTA interpretation.

Indications for emergent CTA Technical considerations/troubleshooting Basic approach to CTA (including discussion of using TeraRecon, other thin clients) Cases (including discussion of pathophysiology, signs/symptoms, imaging approach including tips/pitfalls and what the clinicians need to know from the radiologist, treatment) Acute stroke Aneurysmal subarachnoid hemorrhage Cerebral venous thrombosis Vasopasm Traumatic cerebral vascular injury
