Vascular imaging

Vascular imaging, including CT angiography (CTA), MR angiography (MRA), and catheter angiography are a big part of neuroradiology. When vascular abnormalities are suspected because of clinical exam or findings on other imaging, such as CT or MRI, angiographic exams provide a dedicated way to look for abnormalities in the vasculature. The most common indications for vascular imaging are stroke, subarachnoid hemorrhage, or suspected vascular anomaly/malformation.

Vascular capstone course

Most of the information on vascular imaging and pathology on this site is part of the vascular capstone course. This is a collaborative course I put together with Dr. Cynthia Wu for Emory University 4th year medical students. This course is divided into a couple of parts, including:

The full capstone page has links to the sample scrollable cases that we use for the course as well as some questions you can go through as you review the images. Scroll through the cases and see if you can answer the questions.

Vascular topics

Circle of Willis Overview

Reviews the anatomy of the Circle of Willis, or the confluence of the internal cerebral and basilar arteries within the brain. Learn the normal anatomy, some common variants you may encounter, and a few less common variants.

Intracranial aneurysms

Review intracranial aneurysms, including an overview of what an aneurysm is, how to find them, and tips for searching for aneurysms. The first part of this video covers general principles of aneurysm evaluation and the second part shows 3 sample cases that you can go through to test your individual skills.
