The major teaching points of this educational exhibit are: 1. To review the current diagnostic criteria of vertebrobasilar dolichoectasia utilizing CT, MR, and angiography (DSA) and discuss their limitations 2. To demonstrate the significance and different presentations of VBD  3. To review how to optimize imaging protocols 4. To review available treatment options and future prospects     

The current and available diagnostic criteria, including “Smoker criteria”  The technique of high resolution CT and MR pulse sequences and angiography tailored for evaluation of VBD and the imaging interpretation Multimodality imaging features of compressive and vascular complication How to recognize imaging points of critical importance for treatment planning How to optimize imaging modalities Cases of patients: various clinical presentations: compressive symptoms including hydrocephalus and cranial nerve palsies, for example vertigo, hearing loss, facial palsy, and trigeminal neuralgia, neurovascular symptoms such as transient ischemic attack, ischemic stroke, or hemorrhagic stroke Imaging pitfalls related to thrombus, calcification and flow disturbances and strategies for imaging optimization
