The value of ultrasound contrast agents (USCA) in clinical practice depends on the pharmacokinetics, the signal processing, and the contrast-specific imaging modalities. USCA are exogenous non-toxic substances smaller than red blood cells, which after intravenous administration must be stable enough to pass through the pulmonary capillary bed and enter the blood pool producing the necessary contrast enhancement for the duration of the examination. Recently, second-generation agents, such as SonoVue (Bracco Imaging SpA, Milan, Italy), have been introduced into the market. These agents, taking advantage of the stability of their microbubbles, withstand the acoustic pressure of insonation much better than previous USCA, resulting in an increased half-life of the agent and thus in a prolonged diagnostic window. These agents are blood pool agents that remain in the intravascular compartment and do not leak into the organ tissue. Therefore, they are used to - crease the Doppler signal amplitude during their dynamic vascular phase. Concomitant with the improvement of contrast agents, d- ferent contrast-specific imaging modalities have been developed which, used in combination with USCA and a low mechanical - dex (MI), allow continuous real-time grey-scale imaging. These - cent technical improvements have opened new possibilities in the use of USCA in a variety of indications, as shown in the contributions contained in this book. In the following chapters, some of the most distinguished users of second-generation USCA will share their knowledge and experience. The first contributor is Dr. Thomas Albrecht, Department of - diology, University Hospital of Be
Acoustical imaging has become an indispensable tool in a variety of fields. Since its introduction, the applications have grown and cover a variety of techniques, producing significant results in fields as disparate as medicine and seismology. Cutting-edge trends continue to be discussed worldwide. This book contains the proceedings of the 27th International Symposium on Acoustical Imaging (AI27), which took place in Saarbrucken, Germany, from March 24th to March 27th 2003. The Symposium belongs to a conference series in existence since 1968. AI27 comprised sessions on: Medical Imaging, Non-Destructive Testing, Seismic Imaging, Physics and Mathematics of Acoustical Imaging, Acoustic Microscopy. During two well-attended workshops the applications of quantitative acoustical imaging in biology and medical applications, and in near-field imaging of materials, were discussed. Based on its cross-disciplinary aspects, the authors of the papers of AI27 present experiments, theory and construction of new instruments. "
Written by a pioneer in critical care ultrasound, this book discusses the basic technique and "signatures" of lung ultrasound and explains its main clinical applications. The tools and clinical uses of the BLUE protocol, which allows diagnosis of most cases of acute respiratory failure, are first described in detail. Careful attention is then devoted to protocols derived from the BLUE protocol - the FALLS protocol for diagnosis and management of acute circulatory failure, the Pink protocol for use in ARDS, and the SESAME protocol for use in cardiac arrest - and to the LUCI-FLR program, a means of answering clinical questions while reducing radiation exposure. Finally, the book discusses all the possible settings in which lung ultrasound can be used, discipline by discipline and condition by condition. Lung Ultrasound in the Critically Ill comprehensively explains how ultrasound can become the stethoscope of modern medicine. It is a superb complement to the author's previous book, Whole Body Ultrasonography in the Critically Ill.
This book serves as a comprehensive guide for integrating point-of-care ultrasound into clinical care. It includes detailed chapters on the use of ultrasound in cardiology, dermatology, obstetrics and gynecology, and pediatrics, as well as for the assessment of the abdomen, musculoskeletal system, eyes, and thorax. Over the last decade, the use of diagnostic, point-of-care ultrasound at the bedside has been widely adopted by healthcare professionals in the United States. This technology has spread into many new areas of clinical medicine and more non-radiologists are seeking training and an up-to-date resource on use of the ultrasound machine. This book provides guidance on how to best approach patients with particular problems, practical guidelines on how to operate the machine and choose probes, descriptions and illustrations that depict the patient's position and structures that are scanned, and the anatomy and pathophysiology of each area. Practical Point-of-Care Medical Ultrasound is a valuable addition to the library of any resident, fellow, physician, or other healthcare provider who uses ultrasound in a clinical setting.

For those of us who have been associated with the field of ultrasound imaging of the arterial system since its infancy, this contribution by Friihwald and Blackwell provides the source where the results of over 30 years of hard-won advances can be found. The editors and contributors summarize this burgeoning field in their lucidly written, interesting, and accurate treatise. Beginning with chapters on physical principles and technical considerations, including how to adjust equipment for best images, they consider forthwith carotid and vertebral disease in two outstanding chapters with color images of startling defini tion. Also included are diagrams in which vascular structures are clearly related to well-labeled anatomical landmarks. No other atlas contains the quality of color images and graphic displays which these two editors have compiled. Now that surgical remediation of stenosis of the extracranial carotid and, perhaps, also the vertebral arteries has been demonstrated effective there will undoubtedly be an explosion in the use of this advanced technology to identify appropriate patients and to follow lesions longitudinally over time. To accomplish this, high-quality images made by skilled sonogra phers are the vital component and this book sets standards in this domain."
Mankind has evolved in a sea of radiation. We have been bombarded constantly by X rays, y rays, UV rays, and particulate radiations from outer space, and by terrestrial radiations from the ground we walk on, from our building materials, and from our own bodies. Recently, we have become increasingly subjected to man-made radiations, especially from the medical and defense industries. All of these radiations are capable of affecting us biologically, both to our benefit and to our detriment. This book provides a thorough review of the physical and biological dosimetry of these radiations. It is targeted to those health professionals who are concerned with understanding the mechanisms fundamental to the biological action of ionizing radiation or who are involved in the application, measurement, or treatment of the effects of such radiations. The first chapter, on "Bioeffect Dosimetry in Radiation Therapy," should be of special interest to anyone involved in the treatment of cancer by radiation. It includes a brief review of the history of the manipulation of time-dose parameters in order to improve therapeutic benefit, and an up-to-date analysis of time-dose relationships designed for use in fractionated radiotherapy and brachytherapy. This is followed by two chapters reviewing and comparing national and international protocols for the precise measurement of photon and electron radiations in therapy. These chapters should be invaluable to radiation physicists responsible for treatment machine calibrations.
In this critical area of emergency care, a sound knowledge and understanding of this essential skill is of utmost importance.

Die Ultraschalldiagnostik als nicht invasive Untersuchungstechnik hat in zahlrei- chen Fachern der Medizin bereits einen festen Platz. Eigentumlichkeiten der Ultraschallreflexion knoecherner Strukturen des Hal- tungs- und Bewegungsapparates haben jedoch diesem Untersuchungsverfahren im orthopadischen Fache erst verzoegert Eingang verschafft. Anstoss eines zunehmenden Einsatzes der Sonographie zur Erkennung von Schaden der Weichteilstrukturen des Haltungs- und Bewegungsapparates lieferten die Untersuchungen von R. Graf mit der erfolgreichen sonographischen Fruher- kennung der Huftfehlanlagen. Die Weiterentwicklung dieser Untersuchungstechnik ist sicher noch nicht abgeschlossen. Weitere Problemstellungen in der Orthopadie bieten sich zur sono- graphischen UEberprufung an. Anwendungsmoeglichkeiten und Aussagekraft, wie technische Voraussetzungen der Anwendung der Ultraschalldiagnostik, werden mit knapp gehaltenem Text und zahlreichen Abbildungen, erganzt durch Zeichnungen, in dem Buch "Arthro- sonographie" dargestellt. Irrtumsmoeglichkeiten des Verfahrens werden erlautert. Das vorliegende Buch ist die konsequente Fortfuhrung der Anwendung der Ultraschalldiagnostik in Orthopadie und Rheumatologie und liefert die Basis fur den Einsatz der Sonographie im Praxis-Alltag. Jeder, der sich mit Untersuchungs- techniken am Haltungs- und Bewegungsapparat befasst, wird sich dieser Arbeit dankbar bedienen.

The investigation and management of infertility has progressed radically since the advent of in vitro fertilization. It has ceased to be the province of the gynecologist alone, and often requires the co-operation of gynecologists, andrologists, endocrinologists, embryologists, geneticists, general scientists, psychologists, radiologists, nurses, ultrasonographers, social workers, medical administrators, and lawyers. Many of these do not have a medical background and fewer still have knowledge of the gynecological terms which are still in predominant use. Furthermore, scientific advances have led to the introduction of techniques and terms unfamiliar to the non-scientist, including the gynecologist. This dictionary of reproductive medicine, the first of its kind, has been conceived to address the concerns of all of these groups.
Dieses Buch ist das Ergebnis einer langjahrigen und fruchtbaren Zusam- menarbeit zwischen Ultraschallabteilung und Roentgenabteilung an der Universitats-Frauenklinik Marburg. Eine optimale Kombination aller mammadiagnostischen Massnahmen wurde nicht zuletzt durch die eben- falls in unserem Hause erfolgende Therapie sowie den engen Kontakt zum Pathologischen Institut, besonders zu Herrn Professor Dr. H. KALB- FLEISCH, und eine standige Diskussion der Ergebnisse ermoeglicht. Die Kombination von Sonographie und Mammographie erfolgte bei uns mit der Einfuhrung der handlicheren Real-Time-Scanner, die wir seit 1975 als Punktionshilfen einsetzen. Gleichzeitig wurde an unserer Klinik die Thermographie weiterentwickelt und gepflegt. Seit 1979 konnten Untersuchungsreihen mit einem Immersionsscanner durchgefuhrt werden, die uns die Grundlagen fur die Sonoanatomie der Mamma und ihren Stellenwert zu anderen Verfahren zeigten. Hierbei wurde enger Kontakt zu den richtungsweisenden Gruppen in Australien, Japan und den USA gehalten. Aufgrund der Erfahrungen mit dem Immersionsscanner konnten schliesslich in den letzten 2-3 Jahren wieder handelsubliche Real-Time- Scanner - mit und ohne Wasservorlauf - eingesetzt werden. Ohne Sono- graphie gibt es bei uns heute keine Brustuntersuchung mehr! Die Ultraschalldiagnostik nimmt inzwischen einen festen Platz in der Mammadiagnostik ein. Aufgrund der Weiterentwicklungen (Computed Sonography) ist heute sogar schon Mikrokalk darstellbar. Damit wird eine Ultraschall-Vorsorgeuntersuchung der Brust denkbar. In diesem Buch wird ein Modell vorgestellt, dessen Anwendung fur eine optimale Mammadiagnostik gefordert werden sollte. Wir haben uns bemuht, dem wachsenden Interesse an der Mammasono- graphie durch reichhaltiges Bildmaterial, durch die Beschreibung des Stel- lenwertes der Methode und gesetzlicher Ausfuhrungsbestimmungen entge- genzukommen.
Mit Hilfe der Sonographie lassen sich diagnostische und ope- rative Eingriffe vereinfachen oder sogar erst erm-glichen. Das vorliegende Buch fa t erstmals die interventionellen und intraoperativen sonographischen Techniken zusammen und gibt dem Einsteiger erste Tips f}r ihre praktische Anwendung.
Mit Hilfe der Ultraschalluntersuchung lassen sich sowohl angeborene Veranderungen wie Huftdysplasie und Huftluxation beim Neugeborenen und Saugling als auch entzundliche Veranderungen erfassen. Nach der Anatomie und der normalen Entwicklung des Huftgelenks unter Berucksichtigung der Fruhgeborenen wird die Untersuchungstechnik ausfuhrlich dargestellt. Der Schwerpunkt des Buches liegt auf der systematischen Erfassung diagnostischer Befunde durch qualitative Bildanalyse und Beobachtung der dynamischen Vorgange am Huftgelenk wahrend der Ultraschalluntersuchung. Sehr gut illustriert und kommentiert ist es Lehrbuch und Atlas zugleich.
Das Buch f}hrt den Anf{nger in die routinem{~ige echo- kardiographische Untersuchungstechnik ein und vermittelt ihm gleichzeitig Kenntnisse besonderer kardiologischangio- logischer Krankheitsbilder, dem Fortgeschrittenen werden auch weniger }bliche Techniken der konventionellen Echo- kardiographie erl{utert. Dar}berhinaus wird der Leser ausf}hrlich }ber Methodik, Risiko und Indikationsstellung der osophagusechokardiographiesowie den aktuellen Stand der Kontrastechokardiographie informiert.
