When I asked the registrars what they would like to learn about they said: MRI physics. In my head, I said "crap". MRI physics is a subject that I've learned in the past several times over, and it's easy to forget and get confused. I haven't looked over the material in quite some time, and I didn't have an easy outline or set of prepared slides - crap!
So, I asked for help from several of my colleagues: Drs. Buckwalter, Aisen, and Sandrasegaran all came to the rescue and gave me powerpoint lectures to use. The registrars attended, and were attentive for 6 hours of MRI physics over a few days. This post is a thank you to those who assisted not only me, but many young Kenyan radiologists.
