Informationen zum Autor Ian Elliott trained as a Radiographer and first became involved with MRI in late 1980s. He has worked exclusively in MRI since 1991 and, following an extensive spell scanning human patients, helped pioneer the use of the technique in veterinary practice. Ian has been involved exclusively in veterinary MRI since 2000 and has scanned many thousands of cases during this time. He currently works for Burgess Diagnostics providing MRI services to veterinary surgeons throughout UK and Ireland. Geoff Skerritt is an RCVS Recognised Specialist in Veterinary Neurology, Diplomate of the European College of Veterinary Neurology and former President of the ECVN. In 1997 Geoff was one of the founders of VetMRI, the first mobile veterinary MRI facility in Europe. He is the founder and director of ChesterGates Animal Referral Hospital, a leading multi-discipline veterinary referral centre in the UK. Klappentext The use of Magnetic Resonance Imaging (MRI) in veterinary practice has grown rapidly in recent years and more and more vets are discovering the benefits of MRI to themselves, patients and clients.This is one of the first books aimed specifically at vets using MRI in practice. It not only acts as a useful reference, providing an overview of the basic principles, but it also acts as a practical guide, showing exactly how MRI works and the safety procedures involved. Zusammenfassung Provides an overview of the basic principles, as well as a practical guide to using veterinary MRI. Explains exactly how MRI works and the safety procedures required. Clearly illustrated, including an atlas of anatomy for MRI interpretation. Lists common abbreviations. Suitable for those with or without previous subject knowledge. .

Report
"The MRI images are superb quality and there are many examples of common pathology. The Handbook presents strategies to optimize MRI study via positioning, coil selection, and contrast administration in an easy to understand fashion. The Handbook of Small Animal MRI is a great text to have when performing or interpreting MRI examinations. It provides an overview of the MRI appearance of common diseases and tips on troubleshooting." ( Australian Veterinary Journal , November 2010)
"This book achieves the authors aim of an introductory text to small animal MRI, and would be a worthwhile purchase for any practice using or considering using an MRI facility." ( Veterinary Record, June 2010)
