Hypoxic-ischemic encephalopathy and hyperoxygenation
Contributed by Assoc Prof Frank Gaillard
Hyperoxygenation can not only cause abnormally elevated FLAIR signal in sulci, potentially causing confusion and suggesting blood or meningitis, but also interfere with the normal signal loss seen on SWI from deoxygenated hemoglobin. Oxygen in hemoglobin "shields" the iron molecules from exerting T2* effects 1.
What is Radiopaedia.org?
Radiopaedia is a rapidly growing open-edit educational radiology resource that has been primarily compiled by radiologists and radiology trainees from across the world. Our mission is to create the best radiology reference, and to make it available for free, forever. Find out more here or watch the history of Radiopaedia video below.
Since its inception in 2005, Radiopaedia has grown to become one of the most important medical resources for literally millions of individuals from around the world, particularly those from low and middle-income regions who do not have access to traditional pay-wall resources.

Your first edit
You can update (and write) articles on Radiopaedia. If you see a typo or missing link to an existing article, it's easy to make an edit as soon as you see it. The best way to start is to go to our Editing Radiopaedia Articles Learning Pathway.
Radiopaedia.org comprises two fundamental content types (articles and cases) and playlists (ordered collections of cases).
Articles are collaborative efforts to provide a single canonical page on any and all topics relevant to the practice of radiology. Every edit counts, so don't hesitate to jump in and share what you know. Find out more.
Exceptional cases and up-to-date articles are vital for Radiopaedia.org. Please consider helping by uploading your cases. There is no better way to show your appreciation for the site than by making it even more informative. Add cases by following the case publishing guidelines.
Create and share playlists to help advance medical information around the globe. Curate focused playlists on specific topics for presentations to help other medical professionals teach radiology, or formulate quiz playlists to support medical students in their education. Find out more.
The accuracy of Radiopaedia.org content is overseen by a dedicated group of volunteer editors who constantly review additions and changes to articles and cases, something that is facilitated by being spread around the globe through a variety of time zones.
Our editors also draw upon the knowledge of our expert advisers. Our expert advisers are known to not only be experts in their field and educators but to also support the radiology free open access medical education movement (#FOAMrad).
