"Dr. Jahangiri provides a clear and concise guide for the technologist preparing for the CNIM. In addition, the book covers the basics of IONM and should be a staple reference for the practicing technologist. The book has an easy style and broad coverage of the field of IONM with questions to challenge the reader...this book should be on the shelf of every IONM laboratory."
