About this book
One of the most important developments in diagnostic imaging over the last decade has been magnetic resonance imaging (MRI). Its ability to differentiate between tissues and give patholog ical information about diseases has led to earlier treatment, thus increasing the likelihood of recovery. The images produced using this technique give superb anatomical detail in any plane and are obtained without the use of ionising radiation. The increased use of MRI has presented radiographers with a number of challenges, and because we are no longer dealing with ionising radiation understanding the subject can some times be confusing. We hope that this text will help radiographers and student radiographers to further their knowledge and unravel the mysteries of MRI. Philip T.
