Most MRI physics texts fall into one of two categories. They are either so filled with equations and technical jargon that the average student feels far too intimidated to even open the cover, or they harve over simplified things almost to the point of error. Members of the radiology profession, whether physicians or technologist, are not dummies. Virtually all of them are capable of understanding the real workins of an MRI scanner if it is explained to them properly. Since February 1994 I have been responsible for teaching MR Physics to the residents and technologists at the University of Maryland, Medical Center in Baltimore, Maryland. Alas, I could not find a single textbook that covered all of the important material in what I felt was a clear, conscise yet complete manner. So I developed my own lecture material. To make life easier for my students, I put together handouts that included, on a single page, a pair of 1/4 page reductions of the lecture trans-parencies, a paragraph of explanatory text, definitions, key points and room for notes.
