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.

General vascular topics

These videos address general approaches to vascular imaging, including search patterns and ways you might approach studies.

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.

How to read a CTA of the Head and Neck

In this video, learn how to look at a CT angiogram of the head and neck from start to finish so you can learn how to do it yourself. There are interactive examples that you can follow along on the vascular capstone page.


Vascular pathology

These videos address common vascular pathology, including aneurysms, vascular malformations, and specific ways to identify pathology.

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.

Improve your aneurysm search pattern

This video gives you 5 quick tips that you might use to improve your brain aneurysm search pattern on CT angiograms of the brain.


Brain vascular malformations

Learn the most common vascular malformations and reviews the most common grading system for arteriovenous malformations (AVMs), the Spetzler-Martin grading scale.

Stroke vascular distributions

This video reviews vascular territories in the brain as well as typical appearance of acute infarcts. This covers the distribution of the anterior cerebral artery (ACA), middle cerebral artery (MCA), posterior cerebral artery (PCA), cerebellar arteries, and basilar artery.


This playlist covers a range of topics in vascular imaging including general concepts about how to approach brain and neck vascular imaging, what intracranial aneurysms, are, and how to improve your aneurysm search pattern.
