“I was concerned, watching my residents study mega textbooks, that they were unwieldy and the access to the key information was obscured by unnecessary information.” – Dr. James Thrall

Radiology: A Pretty Clear Choice

I, for the life of me, can’t remember why I wanted to go into medicine — sometimes I question myself — but once I got into medicine, radiology was a pretty clear choice. I had a background in mathematics and it seemed to be a place to bring bioscience and hard science together.

The Requisites: Less Can Be More

The Requisites was founded on the philosophy that less can be more so let’s just provide the information that is important to practice and not all the controversies or the what-ifs that get put in to the mega textbooks. So we ask all the authors to only put in the book what they actually teach at the workstation to their own residents in their own practice. I actually asked the authors not to look up anything, because if they don’t know it, it’s not important enough to go into The Requisites. 

Built from the Ground Up

One of the things that we have asked of each of the authors is not to just add material when they revise their requisites, but to start from ground zero. So the old material gets eliminated and the new material that is pertinent to the current board examination is included.

Friends, Not Books

The most gratifying aspect of The Requisites, to me, as the series editor and co-author of one of the books is to see so many residents studying these books. We wanted to create a series of books that you could actually study. These are not reference books, these are friends, these are part of the life of a resident in radiology.
