Every bone fracture must be held rigid and, because of the long healing process, infringes on the individual's life-style. Treatment with ultrasound, however, may reduce the healing time 30-50% since the piezoelectric effect of ultrasound acts as a callus stimulator. This book documents more than twenty years of clinical experience with ultrasound treatment of fractures. The authors give statistical evidence and show numerous X-rays to document their success. They also include a summary of experimental studies. The method is described in detail so that the practicing physician can easily learn how to apply it.

The measurement of the cerebral circulation in children, particularly in newborns and young infants, has for a long time been high on the list of needs in clinical and scientific pediatrics. The methods available to date have either been too unreliable or unsuitable for use on children. In the course of a research project at the Department of Pediatrics of the Uni versity of Freiburg, Dr. Harald Bode has made the first systematic ex amination of the cerebral circulation of children using transcranial Doppler sonography. Over 500 children with ages between 0 and 18 years were included in this exhaustive study, documenting Doppler measurements in about 3,000 basal cerebral arteries. Basic reference values were obtained which involved adapting the methodology and available equipment to the special re quirements of the pediatrician. Moreover, the influence of biological and physiological factors on these Doppler values has also been considered in addition to those of disease and therapy. The result is an impressive record of the many applications of trans cranial Doppler sonography during childhood. It is not difficult to predict that this methodology will be of lasting value and capable of further de velopment. I hope this book receives the attention it undoubtedly deserves and that the author is able to continue in realizing his fruitful scientific ideas in clinical pediatric practice."

Transcutaneous ultrasonography is an established procedure for diagnosis and therapy in gastroenterology. However, ultrasonic images can often be hampered by pulmonary and intestinal gas and by bony and adipose tissue. In 1956 Wild and Reid reported the first results of transrectal ultrasound of the prostate [1]. In 1976 Lutz introduced an A-mode ultrasonic probe which could be introduced via the biopsy channel of an endoscope [2]. In 1978 and 1980 Hisanaga performed echocardiography using an ultrasonic transducer attached to the tip of a flexible instrument [3, 4]. In animal studies and later on in humans Di Magno has used an echoendoscope in which a small transducer was attached at the tip of a fiberoptic endoscope [5, 6]. The purpose was to overcome the limitations of transcutaneous ultrasonography by directly approaching target lesions with a high-frequency ultrasound source via the gastroin testinallumen. SJlbsequently, the first series of endoscopic ultrasonography (EUS) examinations were reported during the European congress in Stockholm [7]. The purpose of this book is: 1. To evaluate the technique and the equipment for endoscopic ultrasonography 2. To evaluate in detail the endosonographic pattern of the normal and abnormal wall structure 3. To analyze a large consecutive series of various gastrointestinal malignancies in order to determine the usefulness and accuracy of EUS in the detection, staging, and therapy of malignant diseases 4. To compare EUS with other imaging techniques References 1.

This book, the seventh in the series Exercises in Radiological Diagnosis, deals with sonography, an imaging procedure in which the ability of the radiologist plays an exceptionally important role. The author, Catherine Roy, has very extensive experience in the clinical use of sonography. She has selected the images, which are of excellent quality, with great care to illustrate a wide range of conditions and has supplemented them by commentaries and discussions which are easy to comprehend. The systematic use of schematic drawings to interpret the images makes it possible for the reader to follow the author's approach without any difficulty. Schematic drawings are par ticularly important in sonography because the relationship be tween the details in the images and the anatomy may be very weak. Images, schematic drawings, and text (both commentaries and interpretations) are three didactic elements which Cathe rine Roy has skill-fully combined in these exercises into an excellent whole. A.

In 1981, the Norwegian physiologist and cyberneticist, Rune Aaslid, developed a device which made it possible to apply the transcranial Doppler sonographic technique in man. In 1983, Dr. Albrecht Harders took on the project of working out a clinically practicable method that would allow atraumatic measurements to be made of the blood flow velocity in the large branches ofthe circle of Willis. The technique has now become a competitor of the conventional methods of measuring the intracranial hemodynamics, including angiography and the xenon method of cerebral blood flow measurement. Harders proceeded from the assumption that the measurement of the blood flow velocity is more relevant for clinical diagnoses than the usual volume flow measurements. He stresses the very valuable application of the technique in detecting cerebral vasospasm before and after aneurysm surgery. The changes in the blood flow velocities measured by transcranial Doppler sonography in the individual vessel segments of the circle of Willis are interpreted with respect to the various factors that can effect such changes (collateral circulation in the circle of Willis, diameter of the vessel, vascular resistance, the general cardiovascular situation, arterial partial CO pressure, autoregulatory factors, position of body). The rate of 2 complications associated with angiography has thus been reduced, since the best time both for angiography and for surgery can be determined, and continuous TCD examinations show when the patient is out of a critical phase of cerebral vasospasm.

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.

Modern sonography makes possible the detection of small and subtle changes in the normal echo pattern. These may represent significant pathological changes which can not al ways be fully revealed by the echo pattern alone. There is, therefore, an increasing need for the supplement of the ultra sonically guided percutaneous puncture, which can be per formed with great accuracy and with virtually no risk. Also, ultrasonically guided puncture has proven invaluable for a wide variety of therapeutic purposes. The first percutaneous puncture guided by ultrasonic scanning using a specifically designed transducer was per formed in 1969 at the ultrasonic laboratory in Gentofte, now Herlev, Hospital, Copenhagen. The idea was based on a punc ture transducer described and used by Kratochwill for punc ture under the guidance of the ultrasonic A-presentation tech nique. The development in the field formed the basis of the First International Conference on Ultrasonically Guided Puncture at Herlev Hospital in 1978 sponsored by The Danish Society of Diagnostic Ultrasound. The knowledge and experience of the speakers at that conference was compiled in the book "Ultrasonically Guided Puncture Technique" published in 1980. Since then the Society has sponsored a conference at the same place in 1980 and 1983, the latest conference being termed "Third International Conference on lnterventional Ultrasound.""

This book is written by an author whose knowledge of the subject is based on vast surgical experience. A reliable assessment of the success or failure of a micro- vascular anastomosis or an aneurysm operation has until now been possible only postoperatively by angiography and transcutaneous Doppler sonography. Of particular impor- tance are the stenoses and occlusions which can occur dur- ing the operation, but which are frequently not detected un- til after surgery. This induced the neurosurgeons in Freiburg, as well as those in several other hospitals, to carry out a rou- tine control with postoperative transcutaneous Doppler fol- lowing extracranial-intracranial bypass operations and an- giography while still under anesthesia following aneurysm operations. The stenoses and occlusions detected were often not apparent intraoperatively. The reasons for this are that from the outside we see only the surface - and not the lu- men - of a v~ssel, and that stenoses caused by thrombosis, indentation of the vessel wall during anastomosis or by plaque on the vessel wall are not externally obvious. Even arterial pulsation is no guarantee of patency. The necessity to be able to detect stenoses during the op- eration is obvious. The microvascular Doppler sonography adopted by Dr. Gilsbach provides an expedient and safe method of recognizing such lumen narrowings.

This book of diagnostic exercises cannot be used to good advantage without a good grasp of elementary sonoanatomy and the most common pathologic l images . We have tried to follow a pedagogical progression from the simple to the complicated for each group of clinical situations. We recommend that the sonograms at the beginning of each case study be thoroughly analysed before proceeding to the commentaries which explain the grounds for the final diagnosis. These explanatory remarks are accompanied by the same sonograms, but with arrows and letters added so as to pinpoint the details referred to as the diagnosis progresses. In reading the commentaries it will therefore be a good idea to cover over the figures in which the details are picked out for you, uncovering them one by one as required. 1 Which the reader may obtain from our previous books: Ed., 1982) Ultrasonography of Digestive Diseases (Mosby Publ., 2nd Renal Sonography (Springer Verlag, 1981) 1 Chapter 1 In Which the Reader is Invited to Clean His Glasses 1.1. Mrs. Beech, 75 years, has the complexion of a young girl, but she is losing weight and complains of epigastric pain. She has undergone a whole series of conventional radiological procedures; this may be good news for the film manufacturers, but it has not aided in the diagnosis. Finally, she is referred for an ultrasound examination. Look first at ultrasonic cuts 1.1a, b (transverse), then LId (sagittal).

One of the first applications of ultrasound was in submarine sonar equip ment. Since then ultrasound has found increasing applications, particularly in industry, but increasingly in biomedicine. For many years ultrasound has been used in physical therapy, although only in the past decade or two has it evolved from laboratory curiosity to a well-established diagnostic imaging modality. Ultrasound is now a widely accepted, indeed pervasive, diagnos tic and therapeutic tool in the medical field, and its applications are increasing rapidly. Our intent in developing this book is to provide a coherent tutorial intro duction to the field of medical ultrasound at a level suitable for those en tering the area from either medical or scientific backgrounds. The topics discussed should be of interest to nearly all medical and health care per sonnel needing to understand or operate ultrasonic devices, including clini cians, medical technicians, physiotherapists, medical physicists, and other biomedical scientists interested in the field. The book opens with a description of the basic principles of propagating acoustic waves, explains how they interact with a wide range of biological systems, and outlines the effects they produce. To provide practical infor mation to operators of ultrasound equipment, we have included thorough coverage of the details of ultrasonic instrumentation and measurement techniques, and set forth the framework for an effective quality assurance program."

Echocardiography has become an essential tool for good practice of cardiology. Intro duction of 2-D echocardiography has opened a new em of cardiac imaging and investigation. The rapid progress in the field of echocardiography has created an extreme need, now more than ever, for a practical book which is concise, yet complete, well illustrated with good quality tracings and which provides the latest information on the state of the art of combined M-Mode and 2-D) echocardiography. In this book " The Essentials in Echocardiogra phy " Drs. Laurenceau and Malergue have done an excellent job of accomplishing above goals as they discuss the basics of ultrasound, normal examination, and features of various diseases of the heart. The format of presentation, the quality of illustrations and the clarity of discussion point to the thorough and broad echographic experience of these authors. By sharing their experience with us in the form of this well-conceived book, they have done the field of echocardiography a great service. A. J. TAJIK, M. D.

Musculoskeletal ultrasound has seen a considerable surge in usage in recent years. Its advantages are manifold. Given adequate training of the examiner, it is very cost-effective; there is no ionizing radiation to contend with; the scanners are normally highly portable; and it enables certain interventional procedures to be performed with great accuracy (therapeutic injections of local anesthetics and/or corticosteroids into areas of complex anatomy, e.g., the shoulder). In this book, the anatomic areas are organized in chapter pairs, of which the first part of the pair summarizes the diagnostic imaging of that area from various angles so as to obtain the standard images necessary for reliable evaluation. The second part covers the image-guided injection techniques themselves, including requisite equipment. Key Features: Concise texts accompanied by typical US scans, brilliant anatomic illustrations, and many photographs showing proper scanner placement Juxtaposes normal and pathologic anatomy for maximum understanding Detailed and lucid description of all common injection procedures, appropriately illustrated Resteghini's Diagnostic Musculoskeletal Ultrasound and Guided Injection: A Practical Guide is an essential introductory reference for physical therapists, sports medicine physicians, orthopaedic practitioners new to the method, radiographers, and allied health professionals involved in the diagnosis and therapy of musculoskeletal conditions.

Diagnostic and Therapeutic Ultrasound has recently taken an explosive growth for better safer, economic, mobile and high quality healthcare. This technology is very appealing for medical applications because it is non-ionizing, non-invasive and it is available in most of the medical and clinical facilities. Its low cost, when compared with other medical image modalities, makes it one of the preferred tools for medical monitoring, follow-up and diagnosis. Besides the traditional fields of Cardiology and Obstetrics, where it is extensively used for long time, it has became also very useful in the diagnosis of diseases of the prostate, liver and coronaries and carotids atherosclerosis. However, Ultrasound images present poor quality, very low signal to noise ratio and a lot of artifacts. The extraction of useful information from Ultrasound data for diagnosis is a challenge task that makes this medical image modality a very active field of research. The difficulties are being overcome and novel and advanced methods are being proposed for detection, characterization and segmentation of abnormalities in several organs. In fact, Ultrasound application range is vast, covering almost all organs of the human body, including the brain where Tran-cranial Doppler Ultrasound is very important to assess the brain vasculature. This book presents some of the recent advances in Ultrasound imaging technology covering several organs and techniques in a Biomedical Engineering (BME) perspective. The focus of the book is in the algorithms, methodologies and systems developed by multidisciplinary research teams of engineers and physicians for Computer-Aided Diagnosis (CAD) purposes. Cardiovascular and Cancer, the most common life-threatening diseases in western countries, are two of the most important topics focused in the book. However, other advanced issues are also presented such as Intravascular Ultrasound, 3D US and Ultrasound in Computer-Aided Surgery (CAS). Some chapters are direct contributions from medical research groups where Ultrasound has also received great attention in the last decade. By this, new techniques based on Ultrasound were introduced in the clinical practice for diagnosis and therapeutics, mainly in hospital facilities.

In recent years, sonography of the peripheral nervous system has gained widespread acceptance. New diagnostic applications have emerged, and the field of ultrasound-guided interventions has expanded significantly: regional anesthesia, peripheral nerve blocks, and similar techniques are now frequently performed under ultrasound guidance by anesthesiologists and pain physicians alike. This atlas of peripheral nerve ultrasound is designed to meet the daily needs of both radiologists and clinicians by allowing rapid review of typical features, knowledge of which is important for successful diagnosis and intervention. The side by side presentation of ultrasound images with anatomical cryosections and photographs of transducer positions allows for reliable sonographic identification of even tiny nerves in regions of complex topography. The practical value of the atlas is further enhanced by correlations with high-resolution MRI scans.

This book offers readers details in application of high-frequency ultrasound in dermatology, a new method playing increasingly important roles in diagnosis of skin diseases. At first, chapters introduce anatomy and ultrasound features of normal skin. Then terminology, image quality, and artifact of dermatologic ultrasound are presented. After that, ultrasound features of benign and malignant skin tumors, inflammation, autoimmune disease, and traumas are described with diagnostic tips for specific disease. It will be a valuable reference book not only for dermatologist and radiologist, but also for plastic surgeon and cosmetologist.
