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'ecografia è una metodica particolarmente indicata per guidare le procedure interventistiche. L'ecografia interventistica viene spesso impiegata per la diagnosi di malattia.Notevoli e rapidi avanzamenti tecnologici hanno portato alla sempre maggiore diffusione delle procedure interventistiche ecoguidate, modificando in modo significativo le strategie diagnostiche e terapeutiche di molte patologie. Il volume presenta una concisa panoramica delle più comuni procedure interventistiche percutanee e si propone come guida rapida per il radiologo e l'ecografista ai quali, sempre più frequentemente, viene richiesta l'esecuzione di procedure interventistiche su fegato, vie biliari e pancreas sia per fini diagnostici che terapeutici. La trattazione è estesa anche ad altre metodiche di imaging ad integrazione, completamento o quale alternativa alla guida ecografica. Se da un lato è infatti sempre più sentita la necessità di svolgere il ruolo di interventista, dall'altro risulta indispensabile la competenza nella scelta e nell'impiego della metodica più adeguata per la corretta realizzazione della procedura richiesta in relazione allo specifico quesito (diagnosi, terapia e follow-up).

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.

Combining harmonic technology and an ultrasound contrast agent, harmonic imaging now plays a vital role in the diagnosis and treatment of hepatic tumors. Contrast harmonic imaging is especially valuable in cases of hepatocellular carcinoma (HCC), the incidence of which has risen dramatically in Europe, North America, and Asia in recent years. Harmonic imaging is bringing about revolutionary changes in the diagnosis and treatment of HCC, and this book provides the most up-to-date information and guidelines for effective use of this superior technique. Generously illustrated with photographs and diagrams, with accompanying text by a leading expert in the field, this acclaimed book is a valuable state-of-the-art resource for clinicians and researchers in radiology and internal medicine, including hepatology and gastroenterology.

The recent development of sonographic contrast agents (or "microbubbles") has stimulated increasingly intensive studies on the relationships between ultrasound and contrast media. As a result, contrast-specific hard- and software systems have been developed with impressive speed and a new imaging modality, "contrast-enhanced ultrasound" (CEUS), has been introduced. This book is the result of the collaboration of a group of "pioneers" of CEUS, who wish to give the reader a complete overview of second-generation contrast agents, to depict their clinical applications and to present the most updated contrast-specific software for noncardiologic uses, especially for the study of liver diseases. The contents and wealth of illustrations make this volume an invaluable resource for radiologists, hepatologists and oncologists in their everyday clinical practice.

Questo volume fornisce tutte le informazioni attualmente disponibili sull'uso dell'imaging nella diagnosi delle malattie del fegato e delle vie biliari, con particolare attenzione alle possibilità e ai limiti delle singole tecniche diagnostiche. L'approccio multimodale permette allo specialista di integrare l'esame radiologico con la risonanza magnetica, la tomografia computerizzata, la medicina nucleare, l'eco-color-Doppler e l'ecografia così da giungere a un corretto inquadramento diagnostico. L'opera è suddivisa in otto parti: Anatomia, Clinica, Tecniche di studio per imaging e semeiotica, Malattie del fegato, Alterazioni della vascolarizzazione epatica, Malattie delle vie biliari, Radiologia interventistica e Il fegato trapiantato.
