Reviews

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)
