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.
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:
- vascular imaging techniques
- guide to when you might order these specific studies
- a basic search pattern for looking at a CTA of the head and neck
- review of vascular pathologies
- 4 sample interactive cases
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.
