An indispensable resource for anyone performing transcranial Doppler, TCD, and transcranial color Doppler imaging examinations, TCDI, whether novice or advanced level. Step by step instruction for performing transcranial Doppler and transcranial color Doppler examinations. Guidelines for accurate transcranial Doppler interpretation. Tips for difficult TCD exams. A comprehensive post-test examination. 158 pages with color graphics. Techniques in evaluating cerebral blood flow, vasospasm and intracranial stenosis. This manual will be a benefit to both technologist/sonographers and physicians.

Transcranial Doppler (TCD) ultrasound, first introduced more than a decade ago, has steadily evolved into a dynamic, reliable, reproducible, and practical diagnostic tool. Clinical neuroscientists have found TCD to be an indispensable technique in the management of many types of patients. This book is designed to provide basic instruction in the perfor mance and interpretation of transcranial Doppler ultrasonography for technologists, nurses, and physicians. The information included in the text is critical for the development of a strong knowledge base. It is not intended to be all inclusive, and the TCD novice is likely to use it as the platform upon which to build his/her experience in the application of TCD. This book is organized as a step-guided approach for the performance of TCD, and it includes specific guidelines for interpretation of the TCD save forms. We hope that the reader finds it useful during what we think is the most difficult phase of this technique-the learning curve. John P. McCartney, R.V.T. Kathleen M. Thomas-Lukes, R.N., M.N.

Every few years a dissertation comes to the area of clinical application of medical technology which carries us forward as on a magic carpet into new regions of understanding and patient care. This book is such a magic carpet. It brings together, in a clear and incisive fashion, important hemodynamic principles with a simple noninvasive method of application to a part of the cerebral vasculature which has been relatively inaccessible. To the lucky and perceptive person who reads this book, a feeling of excitement and hope for progress is engendered. The diligent application of the potentials of transcranial Doppler ultrasound brings new power to our efforts in understanding the cerebral circulation and the causes, treatment and prevention of cerebrovascular disorders. Merrill P. Spencer, M. D. Director Institute of Applied Physiology and Medicine Seattle, Wash. , July 1986 Acknowledgements I am greatly indebted to Prof. He1ge Nornes, Oslo, who introduced me to the fascinating study of cerebral hemodynamics in the early 1970's and since then continually encouraged my interest in this field. It was through his pioneering work on the cerebral circulation-using peroperative electromagnetic flowmetry and Doppler techniques-that the basis was laid for the noninvasive trans cranial approach to the circle of Willis described in this book. I also gratefully acknowledge the stimulating case discussions with Prof. Peter Huber, Berne, at the very early introduction of trans cranial Doppler, the inspiring exchange of ideas with Dr. Merrill P.

The Second Edition of this highly regarded text provides a current reference source on the clinical and research applications of Transcranial Doppler (TCD) ultrasonography. All of the chapters have been updated to reflect the rapid evolution that has taken place in the field. New information has been included on the increased use of TCD in the operating room, the introduction of contrast media, and the development of new softwares that permit the detection of microemboli.

The use of neurovascular ultrasound is of increasing importance in neurological practice, both for radiologists and increasingly by neurologists themselves. Written by the world’s most renowned expert, this book explains ultrasound examination of a stroke patient scanning protocols interpretation of the results Case examples (with a standard template presentation correlating presentation to waveform output) reinforce the book's practical nature. Illustrated with photos of the tests, explanations, and with actual waveforms, images, and result interpretation, and enhanced with 'pearls' and 'avoiding pitfalls' features, it is a practical reference for those learning ultrasound as well as those using ultrasound in their practices.

Featuring contributions from internationally recognized experts in point-of-care sonography, Emergency Point-of-Care Ultrasound, Second Edition combines a wealth of images with clear, succinct text to help beginners, as well as experienced sonographers, develop and refine their sonography skills. The book contains chapters devoted to scanning the chest, abdomen, head and neck, and extremities, as well as paediatric evaluations, ultrasound-guided vascular access, and more. An entire section is devoted to the syndromic approach for an array of symptoms and patient populations, including chest and abdominal pain, respiratory distress, HIV and TB coinfected patients, and pregnant patients. Also included is expert guidance on administering ultrasound in a variety of challenging environments, such as communities and regions with underdeveloped healthcare systems, hostile environments, and cyberspace. Each chapter begins with an introduction to the focused scan under discussion and a detailed description of methods for obtaining useful images. This is followed by examples of normal and abnormal scans, along with discussions of potential pitfalls of the technique, valuable insights from experienced users, and summaries of the most up-to-date evidence. Emergency Point-of-Care Ultrasound, Second Edition is a valuable working resource for emergency medicine residents and trainees, practitioners who are just bringing ultrasound scanning into their practices, and clinicians with many years of sonographic experience.

Written by several stroke neurosonology experts in Asia, this volume brings together the diverse experiences and skills of a number of leading practitioners in the field. In addition to detailing the ‘science’ behind various neurosonological evaluations, it documents the ‘art’ of performing these tests and provides representative cases encountered in neurovascular laboratories and day-to-day clinical practice. This book will serve as a reference point for sonographers and interpreting neurologists, particularly with regards to transcranial Doppler and cervical duplex examinations.
