Book Description
This is the first book to present an overview of the exciting new cardiac imaging technique of tissue Doppler echocardiography (TDE). In order to understand the background of this technique, it is necessary to compare the physical properties of blood, which reflects ultrasound poorly but moves with high velocity (up to 150 cm/s) with those of the myocar dium, which reflects ultrasound strongly but moves with low velocity (less than 10 cm/s). In tissue Doppler imaging, existing Doppler technology has been modified to bypass the high-pass filter and enhance calculation of low velocities, thus enabling selective visualization of the myocardium rather than of the blood. Because the color Doppler tissue images are super imposed on the conventional two-dimensional ultrasound images, this technique is known as TDE. Following a brief introduction, the history of ultrasound and Doppler imaging is presented. It is now about 150 years since the death of Christian Doppler, who described the "Doppler" effect, and more than 100 years since Pierre Curie discovered the piezoelectric effects of crystals. TDE was developed by Nobuo Yamazaki and Yoshitaka Mine at the Medi cal Engineering Laboratory, Toshiba Corporation, Tochigi, Japan. En gineers involved in the development of the technique have provided important technical information, which the reader will find an invaluable background to potential applications ofTDE.

Book Description
This handbook is intended to help the physician and sonographer to learn echo concepts and techniques in a "user friendly" way, to help them perform studies and understand concepts in order to collect as much clinically useful information as possible on an individual patient. This book is written as a very practical and easy to read manual. Each chapter highlights the various aspects of echocardiography. Practical tips are displayed throughout the book. This text is well illustrated with 165 photographs and graphical illustrations. It will be useful to the echocardiographer and sonographer for practical guidance into performing a thorough goal-orientated study for a particular problem and for the physician/cardiologist in developing the interpretation.

Book Description
Foundations of Biomedical Ultrasound provides a thorough and detailed treatment of the underlying physics and engineering of medical ultrasound practices. It covers the fundamental engineering behind ultrasound equipment, properties of acoustic wave motion, the behavior of waves in various media, non-linear waves and the creation of images. The most comprehensive book on the subject, Foundations of Biomedical Ultrasound is an indispensable reference for any medical professional working with ultrasound imaging, and a comprehensive introduction to the subject for students. The author has been researching and teaching biomedical ultrasonics at the University of Toronto for the past 25 years.

Book Description
The first edition of this definitive text ran to 24 chapters. The second edition, reflecting the explosive growth of interest in echo-enhancement, contains 44. The first section deals with some of the most important emerging issues and technologies and covers harmonic imaging, the use of echo-enhancers to provide quantitative information, and the application of enhanced power Doppler to tissue imaging. The second, on contrast echocardiography, explores the use of echo-enhancement during transesophageal imaging. One chapter describes the use of contrast-enhancement transesophageal imaging to determine coronary flow reserve and another gives a detailed account of the application of the technique to the evaluation of left ventricular function. Other authors describe the intraoperative use of contrast echocardiography and discuss the potential of myocardial contrast echocardiography to replace thallium scintigraphy. Another chapter covers the emerging technique of transient response imaging and its role in the assessment of myocardial perfusion, and two chapters are devoted to three-dimensional contrast echocardiographic assessment of myocardial perfusion. Use of echo-enhancement in the evaluation of peripheral circulation is discussed in chapters on carotid and peripheral arterial flow imaging and others that describe renal and hepatic vascular imaging. The newer applications of echo-enhancement outside the cardiovascular system are described in three chapters devoted to the visualization of tumour vasculature. The final chapters look to the future and cover the imaging of intramyocardial vasculature, the development of site-specific agents and the emergence of the new acoustically active agents.

Book Description
This open access book presents a comprehensive overview of dilated cardiomyopathy, providing readers with practical guidelines for its clinical management. The first part of the book analyzes in detail the disease’s pathophysiology, its diagnostic work up as well as the prognostic stratification, and illustrates the role of genetics and gene-environment interaction. The second part presents current and future treatment options, highlighting the importance of long-term and individualized treatments and follow-up. Furthermore, it discusses open issues, such as the apparent healing phenomenon, the early prognosis of arrhythmic events or the use of genetic testing in clinical practice. Offering a multidisciplinary approach for optimizing the clinical management of DCM, this book is an invaluable aid not only for the clinical cardiologists, but for all physicians involved in the care of this challenging disease.

Book Description
A panel of leading researchers and clinician-scientists distill from years of practical experience and recent scientific and clinical advances the essence of cardiology principles and techniques today. In this second edition, all of the original chapters have been extensively rewritten and two new chapters on acute coronary syndromes following the modern classification have been added: one on unstable angina pectoris and non-ST-segment elevation myocardial infarction, and the other on ST-segment elevation myocardial infarction. Compact yet comprehensive, Essential Cardiology: Principles and Practice, Second Edition offers today's busy cardiology and internal medicine practitioners, cardiology fellows, and medical residents rapid access to the latest ideas and techniques needed for today's gold standard diagnosis and management of cardiac patients.

Book Description
ATLAS OF EQUINE ULTRASONOGRAPHY A THOROUGH EXPANSION TO THE FIRST ATLAS OF ULTRASONOGRAPHY IN THE HORSE, WITH NEW AND SIGNIFICANTLY IMPROVED IMAGES Ultrasonography is a vital diagnostic tool that can be applied in numerous functions in a veterinary practice. In conjunction with relevant clinical information—patient history and physical examination findings, for example—it can act as an important aid in the veterinarian’s decision-making process. Many vets in equine practice rely upon ultrasonography as a mainstay of equine diagnostic imaging on a wide range of structures and body systems. Ultrasonography is a useful procedure that is non-invasive and acts in complement to radiography to successfully diagnose the animal’s condition. This book’s aim is to encourage the clinician to rely further on the use of ultrasonography in their practice. The second edition of Atlas of Equine Ultrasonography provides an updated and expanded revision of the first atlas of ultrasonography in the horse. The first edition of this important resource was the first pictorially-based book to cover ultrasonography in the horse, and remains the only book currently available on the subject. The current version offers 450 additional images with greater clarity and precision in the images throughout and demonstrates how to obtain images in each body region while offering clinical ultrasonograms that show pathology. Atlas of Equine Ultrasonography readers will also find: High-quality clinical ultrasonograms for important musculoskeletal, reproductive, and medical conditions in the horse More than 1,500 images, with accompanying concise text describing the images A companion website that provides video clips showing dynamic ultrasound exams Atlas of Equine Ultrasonography is an invaluable reference to any veterinarian evaluating ultrasonograms in equine patients. As a result, this book will be of particular interest to equine specialists, veterinary radiologists, equine practitioners, and veterinary students.
