Endoscopic ultrasound (EUS) is now considered one of the most essential and cost-effective techniques in the assessment of a wide range of gastrointestinal diseases. A remarkably versatile, minimally invasive procedure, it also calls for a high level of anatomic knowledge and technical prowess. This revised and updated lavishly illustrated volume -- a textbook and atlas in one -- offers medical professionals the most comprehensive overview of EUS available, as well as a wealth of valuable insights from leaders in the field. Features: More than 1000 high-quality images Logical, easy-to-use structure, including the requisite anatomy and pathology Strategies for selecting patients and procedures, including hygiene requirements, informed consent, patient positioning and monitoring, and more Precise clinical descriptions and valuable tips and techniques for diagnosis and treatment Guidance on the successful handling of needling and catheters Insightful discussions of the uses and limitations of evolving techniques Chapters on contrast-enhanced EUS techniques and SonoElastography, new chapters on "Hot Spots of Interventional EUS" and Portal Hypertension. Accompanying DVD with over 60 video sequences and 30 still images on selected topics Written for specialists and trainees in gastroenterology, pneumology, and surgery, Endoscopic Ultrasound -- with its broad scope and up-to-date information -- is essential reading for anyone wishing to explore and exploit the potential of state-of-the-art EUS.

Ultrasound continues to be one of the most important diagnostic tools in medicine and is used by a wide range of healthcare professionals across many applications. This book provides a practical, clinically relevant guide for all practitioners working in the field of abdominal ultrasound. Its aim is to enable the operator to maximize the diagnostic information and recognize the limitations of ultrasound scans.

L'introduzione e l'affermazione dell'ecografia,TC e risonanza magnetica nell' iter diagnostico hanno indubbiamente modificato l'approccio alla patologia dell'età pediatrica.La ricchezza d'informazioni e l'innocuità della tecnica rendono l'ecografia esame di prima scelta , dopo la valutazione clinica.Il libro, concentrandosi sullo studio dell'apparato gastrointestinale e sulle patologie , prima dominio della radiologia tradizionale , è " una primizia" nel campo ecografico limitato in passato allo studio dell'addome e degli organi parenchimatosi.

L'opera presenta un'analisi completa delle applicazioni dei mezzi di contrasto ecografici a livello addominale

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.

Endoanal and endorectal ultrasound represents considerable progress in the field of anorectal imaging. Its importance in the staging of rectal and anal cancer, in identifying perianasto- motic neoplastic recurrences, in defining acute and chronic suppurative disease and in assessing sphincteral anatomical integrity, is now a confirmed reality. The evidence provided by endoanal and endorectal ultrasonography guides the colorectal surgeon in his choice among the various therapeutic approaches and helps in assessing the effects of the treatments applied. The great flexibility and high degree of reliability make this exploratory method an indispensable tool at all stages of the clinical course in the majority of patients with anorectal problems, including the fundamental follow-up stage. The publication of this excellent volume on intraanal and intrarectal ultrasonog- raphy is therefore to be appreciated, especially since it is in the form of an atlas. As we are dealing with imaging, it is particularly appropriate that it is the images that tell the story. Like all important things, this volume does not come out of nothing. It is the result of many years of skilled work by Drs. G.A. Santoro and G. Di Falco and is based on the experience of internationally renowned professional experts. The ten sections of the atlas begin with general information on ultrasonography, gradually progressing to the technical problems of the method and the aspects rela- tive to anorectal tumors.This last section leads to a review of traditional and mod- ern therapeutic possibilities.

This specialist volume is the first English-language textbook to present a comprehensive view of the sonographic aspects of abdominal transplantation, from pre-assessment of the patient to examination during the peri-operative period and on through follow up. Extensively illustrated, the text gives in-depth treatment to the color doppler techniques critical in modern practice as well as other imaging modalities useful in the transplantation of the kidneys, pancreas and small bowel. Transplant physicians and surgeons, along with those radiologists and sonographers involved in the assessment of transplant patients, will find this book an invaluable practical reference.

L'obbiettivo prioritario è offrire ai giovani medici che vogliono avvicinarsi alla tecnica ecografica un testo semplice da leg

With the ever-increasing demand for cost-effective care, endoscopic ultrasonography (EUS) represents the best and least expensive way of performing biopsies of many gastrointestinal cancers and regional lymph nodes. "Gastrointestinal Endosonography" brings you the most comprehensive, abundantly illustrated guidance available on this essential technology. 31 pioneering endosonographers from France, Germany, Italy, Japan, Norway, and the USA explain precisely how to use EUS with maximum effectiveness in a wide variety of applications.

L'occlusione meccanica dell'intestino tenue rappresenta una problematica clinica di frequente riscontro, la cui gestione clinico-strumentale è resa difficile dalla complessità dei meccanismi responsabili del quadro occlusivo. Il ruolo del radiologo è quello di orientare tempestivamente l'iter terapeutico sulla base di una corretta interpretazione dei quadri iconografici. Lo scopo di questo volume -unico nel suo genere- è quello di correlare la fisiopatologia dell'occlusione all'imaging. La ricca iconografia, che spazia dall'esordio clinico alla risoluzione, enfatizza il ruolo della tomografia computerizzata multidetettore con mezzo di contrasto per via endovenosa, che è il gold standard attuale. Tuttavia, non vengono dimenticate le correlazioni con le metodiche eco-radiografiche, che conservano un efficace ruolo diagnostico, a basso costo biologico ed economico. L'ileo meccanico del tenue è un esempio eclatante a sostegno del sogno di molti addetti ai lavori: quello, cioè, di avere una figura di fine radiologo dell'emergenza addominale, esperto di organo e di malattia e non solo di macchina, come spesso purtroppo accade.
