Impressive!
Very impressive application: well written, provides a wealth of knowledge and the content can easily be accessed through dynamic indexing. It is so much more than a quick reference, there's stuff in here to keep me studying for quite a while. I find it a great new way of doing radiology, it really puts the future of radiology learning at your fingertips. Well worth the investment! And the design of it is great too, the people behind this app have really thought of everything ;-)
