A basic text and instruction manual of diagnostic ultrasound which is directed towards the student or health care provider- non-radiologist and non-sonographer- wishing to begin performing and understanding ultrasound. It covers basic concepts of diagnostic ultrasound. While the emphasis is on obstetric ultrasound, it also includes applications for gynecology, trauma, abnormal fluid collections, liver and biliary diseases, hydronephrosis and renal disease, and small parts (e.g. breast, thyroid, testicle, extremity, etc.). A primary goal is to teach the practitioner how to use ultrasound to help determine which patients should be referred to a center where a higher level of care can be provided. The book was initially conceived and created for practitioners in rural low resource areas but would be useful in a wide variety of settings.

A straight forward, easy reference to the most common injection sites. - Photos displaying patient and probe positioning - High resolution ultrasound images with needle visualization - Clinical tips and "pearls"

Ultrasound plays an integral part in the diagnosis and management of many gynaecological conditions; indeed, ultrasound forms part of the RCOG's mandatory training programme for doctors wishing to specialise in obstetrics and gynaecology. This book will be of use to both trainees and those already in clinical practice looking for a user-friendly reference guide. The use of ultrasound in gynaecology goes well beyond simple picture recognition: a skilful gynaecological sonographer will bring together scan findings and the clinical scenario to enhance patient care. This leads to targeted investigations and strategies for intervention. This book covers all aspects of the use of ultrasound in the fields of gynaecology and early pregnancy, with the contents including: postmenopausal bleeding; adnexal masses; pelvic pain; reproductive medicine; miscarriage; ectopic pregnancy; and ovarian cysts.

The present volume on basic physics of ultrasonographic imaging procedures provides clear and concise information on the physics behind ultrasound examinations in diagnostic imaging. It attempts to present the subject from a simple approach that should make it possible for the target groups to comprehend the important concepts which form the physical basis of ultrasonic imaging. The main target group of this manual is radiological technologists and radiographers working with diagnostic ultrasound in developing countries.Clinicians and nurse practitioners may also find the simple presentation appealing. A conscious effort has been made to avoid detailed mathematical treatment of the subject. The emphasis is on simplicity.

A didactic, illustrated guide to the use of ultrasound as a diagnostic tool in clinical practice. Prepared by an international group of experts with wide experience in both developed and developing countries, the manual responds to the need for a basic reference text that can help doctors, sonographers, nurses, and midwives solve imaging problems when no experts are available. With this need in mind, the manual adopts a practical approach aimed at providing a thorough grounding in both the techniques of ultrasound and the interpretation of images. The need for extensive supervised training is repeatedly emphasized. Because the clinical value of ultrasound depends so greatly on the experience and skill of the operator, the manual makes a special effort to alert readers to common pitfalls and errors, and to indicate specific clinical situations where ultrasound may not be helpful or reliable as a diagnostic tool. Explanatory text is supported by numerous practical tips, warnings, checklists and over 600 illustrations. The opening chapters explain how ultrasound works, outline the factors to consider when choosing a scanner, and introduce the basic rules of scanning, including advice on how to recognize and interpret artefacts. Guidance on the selection of ultrasound equipment includes clear advice concerning where costs can be spared and where investment is essential. The core of the manual consists of seventeen chapters providing guidance on scanning techniques and the interpretation of images for specific organs and anatomical sites, with the most extensive chapter devoted to obstetrics. Each chapter contains illustrated information on indications for scanning, preparation of the patient, including choice of transducer and setting of the correct gain, general scanning techniques, and specific techniques for identifying anatomical landmarks and recognizing abnormalities. The manual concludes with WHO specifications for a general-purpose scanner judged entirely suitable for 90-95% of the most common ultrasound examinations.

Lo studio delle malformazioni fetali rappresenta uno degli argomenti piu complessi nell ambito della medicina fetale.

Negli ultimi anni il ruolo della risonanza magnetica (RM) nell inquadramento diagnostico delle malformazioni fetali isolate e complesse e divenuto sempre piu importante, attestandosi come esame di III livello.

Tale incremento e stato possibile grazie all implementazione tecnologica delle apparecchiature di RM e quindi allo sviluppo di sequenze veloci e ultra veloci.

La RM, solitamente effettuata dopo un ecografia di II livello a partire dalla 19a settimana di gravidanza, puo quindi rappresentare, in casi selezionati, un importante completamento diagnostico nella valutazione di quadri malformativi complessi e nella programmazione di interventi terapeutici nella vita intrauterina e nel postnatale. E necessario sottolineare l importanza di centri di riferimento dedicati e la presenza di un team multidisciplinare per la corretta gestione dei piccoli pazienti.

Il volume e suddiviso in tre parti. Dopo una prima parte piu tecnica, viene trattata l anatomia fetale in RM con attenzione all evoluzione dei singoli organi; la terza parte analizza invece i principali quadri malformativi con particolare riguardo al distretto encefalico, toracico e addominale. Il testo e arricchito da un estesa documentazione iconografica.

Questolibro vuole essere di rapida e facile consultazione e rappresentare un punto di partenza per il radiologo e il neuroradiologo, nonche per tutti gli specialisti interessati alla medicina fetale e in particolare alla risonanza magnetica.

L'ecografia e utile nella valutazione di patologie articolari in pazienti con malattia reumatica e, oltre che nella diagnosi, e efficace nel monitoraggio con power Doppler della sinovite, con una sensibilita superiore rispetto all'esame clinico. L'ecografia ad alta risoluzione, integrata con la tecnica power Doppler, e anche in grado di individuare le anomalie entesopatiche, l'erosione ossea e il coinvolgimento del tendine. L'obiettivo dell'opera e di presentare la tecnica d'esame, i progressi ecografici nella patologia reumatica muscoloscheletrica e il ruolo diagnostico della ecografia nella patologia reumatica articolare. L'iconografia e arricchita con immagini integrate di ecografia, radiologia convenzionale, TC e RM.

Il ruolo che la diagnostica per immagini riveste nella pratica clinica quotidiana e di giorno in giorno sempre piu rilevante: il moderno radiologo deve possedere un approfondita conoscenza della clinica e dell anatomia patologica e la capacita di correlazione con i reperti radiologici, al fine di poter cogliere anche i minimi segni e reperti rilevabili.

Inoltre, la vastita delle attuali conoscenze richiede non solo una preparazione radiologica generica, ma anche e sempre piu approfondimenti sub-specialistici: cio conduce alla formazione di radiologi d apparato e in alcuni casi d organo, in grado di utilizzare al meglio tutte le tecniche attualmente disponibili, cosi da percorrere correttamente l iter diagnostico, insieme ai colleghi specialisti di altre branche mediche.

Nel presente manuale, che raccoglie 100 casi ben selezionati e significativi, gli Autori dimostrano come, partendo dalla storia clinica del paziente e sfruttando al meglio le tecniche di imaging, sia possibile giungere alla diagnosi: in tal modo, si riduce il ricorso a procedure invasive e a indagini inutili e/o superflue. Grazie al taglio pratico e alla concisa trattazione del testo, i giovani radiologi e gli specializzandi hanno a disposizione un valido e rapido strumento di conoscenza del corretto approccio, approfondimento e aggiornamento della disciplina."

High intensity focused ultrasound (HIFU) is an increasingly popular physical tool with a wide range of applications in medicine. One of the drivers of this advancement is the development of ultrasound phased arrays, which, although more complex and costly than the traditional single focused bowl transducers used in earlier studies, are capable of electronically controlled dynamic focusing. Such systems not only steer a single focus without movement of the array itself, but can also generate several foci simultaneously and create focal regions with complex configurations. This book addresses the design, research and development, and medical applications of both relatively small HIFU arrays that can be inserted into body cavities (so called linear arrays) and larger two dimensional arrays for extracorporeal use. A key safety issue in the design of these arrays is to ensure that only targeted tissue is exposed to high levels of acoustic intensity and in this regard, this book highlights the advantages of designs involving spatial randomization of array elements to reduce the level of potentially dangerous grating lobes. In particular, phased arrays with a random distribution of elements are discussed and compared to regular arrays, and methods for calculating ultrasound fields generated by different phased arrays including the generation of multiple simultaneous foci and focal regions with complex geometrical shapes are presented. A detailed discussion of the influence of the dimensions, number, and shape of individual elements, errors in phase setting at the elements, and the frequency modulation of the signal on the quality of the intensity distributions produced by random arrays is included.

Multiple pregnancies are associated with higher risks for both mother and babies. Women with multiple pregnancies have an increased risk of miscarriage, anemia, hypertensive disorders, haemorrhage, and postnatal illness. These pregnancies are more likely to need an operative delivery, and maternal mortality is generally 2.5 times that of singleton births. Fetuses are at increased risk for anatomic and genetic anomalies, growth abnormalities, prematurity, and several physiological problems related to monochorionicity. This book provides a much needed, up-to-date guide to the management of multiple pregnancies. Presented with a uniform approach to all chapters, information is easily navigable, evidence-based, and highly practical. Heavily illustrated, particularly with ultrasound images - the cornerstone of management of multiple pregnancies - this book will appeal to obstetricians and specialists in maternal-fetal medicine, midwives and ultrasonographers and will improve outcomes for mothers and babies.
