BEWARE, this app has not been updated in years and therefore references outdated guidelines.
Accurate, easy to use, even cites sources and provides links to them. Helpful for radiology residents trying to learn it all.
This is an amazing resource. I use it every day.
Thank you for making this app. It is very helpful and easy to use.
