To demonstrate normal and variant venous anatomy as well as exhibit cases of venous pathology and their mimics as seen on routine head and neck CT Angiography (CTA).

1. Discuss optimization of head and neck CTA protocol A) Bolus B) Data acquisition C) Reconstruction and rendering techniques 2. Demonstrate normal venous anatomy and common variants A) Variable configuration of the torcular herophili B) Asymmetry of the deep and superficial cerebral veins C) Variable drainage patterns 3. Illustrate common pathologic conditions of the cerebral venous system A) Venous sinus thrombosis B) Arteriovenous malformation C) Venous varices D) Developmental venous anomaly E) Vein of Galen malformation 4. Show examples of pathologic mimics, common artifacts and potential interpretive pitfalls in the cerebral venous system A) Lack of temporal resolution B) Superimposition of opacified arteries, adjacent bone, hemorrhage, etc. C) Streak, motion, mottle, and impact of calcification on image reconstruction and interpretation  

Knowledge of cerebral venous anatomy as well as an awareness of its variability, pathology and potential diagnostic pitfalls is imperative for the accurate interpretation of CTA of the head and neck.
