This updated textbook provides an essential evidence-based approach to echocardiography and includes practical case-based instruction illustrating a wide variety of clinical scenarios in which echocardiography is a vital diagnostic option for physicians. It reflects how echocardiography has evolved into a complex multimodality method for evaluating and quantifying cardiovascular lesions, and explains the use of hemodynamic assessment of the heart using echocardiography, transesophageal and three-dimensional echocardiography, deformation imaging and assessment of myocardial perfusion, which have added a new dimension to real-time noninvasive evaluation of patients. Echocardiography highlights the clinical utility of these evolving modalities that are now crucial to the renaissance of echocardiography, and it provides a thorough clinical review of this most revealing and adaptable methods of imaging a patient. The Editors and their world-class group of contributors have created an essential reference for those in training or who already use echocardiography in their practice.

This book comprehensively highlights modern emergency radiology diagnosis of the acute abdomen. In traumatic as well as non-traumatic emergencies, the clinical term "acute abdomen" refers to a variety of serious conditions in an often progressive clinical situation that call for an immediate diagnostic and therapeutic intervention. Today, thorough and rapid diagnostic radiological imaging is broadly available and the radiologist has gained a central role in patient handling in many emergency medicine departments. In addition to proficient radiological knowledge, communication and close co-operation among the various specialists involved are essential for successful patient management. Emergency radiologists must not only acquire a full understanding of the imaging modalities and technical requirements, but they should also have appropriate clinical knowledge of the various disorders in order to become valuable contributors to the therapy decision-making process. Emergency Radiology of the Abdomen provides a comprehensive review of the etiology, pathophysiology, and clinical presentation of acute abdominal conditions, both after traumatic events and in the non-traumatic setting. It focuses on imaging features and high-end emergency radiology that are indispensable for a timely management approach. Numerous high-quality images, diagrams, and easy-to-read tables are provided.

This book provides basic information about the relatively new and evolving technology -positron emission tomography- for its clinical applications and practical guidance for the referring physicians. Chapters cover application of PET in various clinical settings including oncology, cardiology, and neurology with a focus on role in various cancers. Because most of the new PET equipments come as hybrid machines with CT or MRI, two chapters have been included at the end of the book to provide basic and comprehensive information about these two technologies. Molecular imaging is going to revolutionize the way we practice medicine in the future. It will lead to more accurate diagnosis of diseases and its extent which will lead to better management and better outcomes. In the history of medicine no imaging modality has ever become so popular for use in such a short time as has the PET technology. PET imaging is mostly used in oncology, neurology and cardiology but also finds application in other situations such as infection imaging. The main focus, of course, is in management of cancer patients. PET (PET-CT) is not only very sensitive as it can detect changes in abnormal biochemical processes at cellular level but in one go all such areas can be detected in a whole body scan. It can show response to therapy, eradication of the disease or recurrence during the follow-up period. One of the main differences between a PET scan and other imaging tests like CT scan or MRI is that the PET scan reveals the cellular level metabolic changes occurring in an organ or tissue. This is important and unique because disease processes begin with functional changes at the cellular level. A PET scan can detect these very early changes whereas a CT or MRI detect changes much later as the disease begins to cause changes in the structure of organs or tissues. Some cancers, especially lymphoma or cancers of the head and neck, brain, lung, colon, or prostate, in very early stage may show up more clearly on a PET scan than on a CT scan or an MRI. A PET scan can measure such vital functions as blood flow, oxygen use, and glucose metabolism, which can help to evaluate the effectiveness of a patient's treatment plan, allowing the course of care to be adjusted if necessary. Apart from its vital role in oncology it can estimate brain's blood flow and metabolic activity. A PET scan can help finding nervous system problems, such as Alzheimer's disease, Parkinson's disease, multiple sclerosis, transient ischemic attack (TIA), amyotrophic lateral sclerosis (ALS), Huntington's disease, stroke, and schizophrenia. It can find changes in the brain that may cause epilepsy. PET scan is also increasingly being used to find poor blood flow to the heart, which may mean coronary artery disease. It can most accurately estimate the extent of damage to the heart tissue especially after a heart attack and help choose the best treatment, such as coronary artery bypass graft surgery, stenting or medical treatment. It can also contribute significantly in identifying areas exactly where radiotherapy is to be targeted avoiding unnecessary radiation exposure to surrounding tissue.

A comprehensive guide to the conceptual, mathematical, and implementational aspects of analyzing electrical brain signals, including data from MEG, EEG, and LFP recordings. This book offers a comprehensive guide to the theory and practice of analyzing electrical brain signals. It explains the conceptual, mathematical, and implementational (via Matlab programming) aspects of time-, time-frequency- and synchronization-based analyses of magnetoencephalography (MEG), electroencephalography (EEG), and local field potential (LFP) recordings from humans and nonhuman animals. It is the only book on the topic that covers both the theoretical background and the implementation in language that can be understood by readers without extensive formal training in mathematics, including cognitive scientists, neuroscientists, and psychologists. Readers who go through the book chapter by chapter and implement the examples in Matlab will develop an understanding of why and how analyses are performed, how to interpret results, what the methodological issues are, and how to perform single-subject-level and group-level analyses. Researchers who are familiar with using automated programs to perform advanced analyses will learn what happens when they click the "analyze now" button. The book provides sample data and downloadable Matlab code. Each of the 38 chapters covers one analysis topic, and these topics progress from simple to advanced. Most chapters conclude with exercises that further develop the material covered in the chapter. Many of the methods presented (including convolution, the Fourier transform, and Euler's formula) are fundamental and form the groundwork for other advanced data analysis methods. Readers who master the methods in the book will be well prepared to learn other approaches.

This book covers the full range of current applications of Doppler sonography in infancy and childhood, describing the variety of potential findings with the aid of a wealth of images. After an introductory chapter on the physical and technical basis of Doppler sonography, applications of cerebral Doppler sonography in infancy and of transcranial Doppler sonography in childhood are addressed, with numerous examples of imaging appearances. The major part of the book is devoted to Doppler sonography of the brain, face and neck and of the abdomen, covering normal abdominal vessels, liver, spleen, pancreas, and mesenteric and renal circulation. Imaging of the ovaries and testes is also presented, encompassing the differential diagnosis of acute scrotum and other space-occupying lesions of the testis. The book closes by considering Doppler sonography of soft tissue and vascular malformations, and the influence of congenital heart malformations on flow parameters in peripheral arteries. Doppler Sonography in Infancy and Childhood will be an invaluable reference for pediatricians, neonatologists, pediatric sonographers, and pediatric and general radiologists.
