From the reviews:
"This introductory book is designed to take readers from the fundamentals of proton interactions to the interpretation of clinical MR imaging studies. ... All healthcare professionals are the intended audience. The book is certainly suitable for radiologists interested in MRI or MR technologists wanting to learn the essentials of the technique. ... provides a good starting point for those involved in MR imaging with a clinical perspective. It is well-illustrated and practically demonstrates how physical principles directly govern the images of any MR imaging study." (R. Terry Thompson, Doody’s Review Service, March, 2009)
