Totally Accessible MRI - Michael L. Lipton

. .

Résumé :
This practical guide offers a lucid introduction to the principles of MRI physics. The author, recognized in the imaging community for his exceptional teaching methods and lectures, presents complex material in a highly accessible way. Each chapter explains the why and how behind MRI physics. Readers will understand how altering MRI parameters will have many different consequences for image quality and the speed in which images are generated. Practical topics, selected for their value to clinical practice, include progressive changes in key MRI parameters, imaging time, and signal to noise ratio. A wealth of high quality illustrations, complemented by concise text, enables readers to gain a thorough understanding of the subject without requiring prior in-depth knowledge....

From the reviews: This book presents a nonmathematical introduction to magnetic resonance imaging (MRI), covering all major topics ... . The author, an expert in body MRI, has covered the major topics that are relevant for residents, physicians, students, and technologists. ... Overall, this is a good introduction that will be useful for people entering the MRI field; the nonmathematical derivations can be grasped easily. The step-by-step pulse sequence breakdown is useful and interested readers will be able to seek the further information without any difficulty. (Michael A. Jacobs, Doody's Review Service, September, 2008) Totally Accessible MRI provides an introduction to the principles of magnetic resonance (MR) imaging physics and practical use of MR imaging technology. ... It will probably be most useful to residents beginning their MR rotations particularly those with an interest in neuroradiology. It also provides a concise review for my one interested in a deeper understanding of MR imaging and it is likely that even expert users will pick up a few pearls along the way. (James F. Glockner, Radiology, Vol. 255 (2), May, 2010)
