Ecografia

This long-awaited new edition is still the only source devoted entirely to ultrasound measurements. Inside, you'll find the most accurate coverage for all major pathologic entities - from the abdomen to the vascular system. Each measurement is based on an evidence-based approach in correlation with age, sex, and gestation stage. Coverage also includes the latest technologies, such as color Doppler.

This user-friendly second edition provides a practical introduction to gynaecological ultrasound. It describes and explains background anatomy and physiology, instrumentation and how to make the best use of equipment. Emphasis is placed on how to maximise image quality, and how to recognise normal and pathological features. The volume also assesses other relevant diagnostic techniques and various management strategies, and evaluates the role of ultrasound as part of patient management. It includes chapters on pathology of the uterus, ovaries and adnexae, paediatric and trauma cases, together with management of infertility and other gynaecological perspectives of patient management. Illustrated throughout with numerous high-quality ultrasound images and line drawings, many of them new for this latest edition, this is essential reading for practitioners in training, including radiologists, gynaecologists and sonographers.

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 Berlin, Germany.

Featuring over 700 illustrations, this book is a practical, visual guide to performing and interpreting ultrasound and using ultrasound findings for making clinical decisions in the emergency department. Consistently formatted chapters cover both common and less common uses of ultrasound in the emergency department. Each chapter includes clinical applications, anatomy and landmarks, image acquisition, pathology, clinical decision making, incidental findings, and clinical examples. High-quality images include patient photographs demonstrating the correct probe placement and large ultrasound images allowing findings to be easily seen. Labels on ultrasound scans and side-by-side anatomic drawings help readers locate the key parts of all images.

Written by well-known leaders in ophthalmic ultrasonography, this volume is a complete guide to the use of ultrasound as a primary diagnostic tool in ophthalmology. This thoroughly revised Second Edition reflects the latest developments in three-dimensional ultrasound and other advanced technologies and the expanding clinical role of ultrasound, including its use in refractive surgery, post-LASIK evaluation, and neuro-ophthalmology. Coverage includes detailed chapters on ocular diagnosis, orbital diagnosis, and very high-frequency digital ultrasound scanning in LASIK and phakic intraocular lenses. More than 200 full-color, two-color, and black-and-white illustrations complement the text. A bound-in DVD contains video clips of patient ultrasound examinations.

The field of noninvasive vascular diagnosis is expanding, and there is a need in this field for a concise overview of the various imaging options available to the vascular team. In the last 5 years, the vascular center has become a standard model for vascular diagnosis and treatment with representatives from the worlds of vascular surgery, interventional radiology, cardiology, and vascular medicine. This book, edited by Drs. Mansour and Labropoulos, describes all of the various diagnostic options available today in 50+ chapters. Experts from various fields tackle vascular imaging of cerebrovascular disease, peripheral atherosclerotic occlusive disease, intra-abdominal occlusive disease, venous disorders, and aneurysms. Additional topics range from basic science subjects, such as ultrasound physics and instruments to coding and reimbursement issues.
