This book examines in detail the diagnostic impact of contrast-enhanced ultrasound in the evaluation of urinary tract pathology, paying particular attention to the diagnostic gain that may be expected in relation to other imaging techniques such as CT and MRI. The role of contrast-enhanced ultrasound is evaluated in a range of pathologies, including ischemia, trauma, inflammation, cystic lesions, and solid tumors, as well as in the imaging of anatomic variants. New applications, for example monitoring of kidney transplantation, assessment of urinary bladder lesions, and diagnosis of vesico-ureteric reflux, are also covered. The presented cases, drawn from the authors' personal clinical caseload, include images obtained using multimodality techniques, sometimes with 3D CT reconstruction. The authors' own experiences are compared with the most recent reports in the scientific literature.
This book offers a comprehensive guide to the technical basis of laser ablation, describing and reporting in detail on the latest findings. The world of medicine is currently working to reduce the invasiveness of treatment, in order to improve patients' quality of life. Image-guided ablations are rapidly becoming an effective alternative to several surgical treatments. Among the many techniques available for ablation, laser is still not widely used, though its efficacy has been amply demonstrated. The scientific community is now showing a growing interest in laser techniques for image-guided ablations, and many physicians are willing to start using lasers in their clinical practice. The book is divided into 16 chapters, including historical notes, technical aspects, outcomes of ex-vivo experiments, and results of the application of this technique in various clinical scenarios. It will be of great interest to a broad range of physicians (interventional radiologists, surgeons, gastroenterologists, endocrinologists, urologists), from less experienced trainees to expert physicians who want to introduce a novel clinical practice.
Motivated by a variational model concerning the depth of the objects in a picture and the problem of hidden and illusory contours, this book investigates one of the central problems of computer vision: the topological and algorithmic reconstruction of a smooth three dimensional scene starting from the visible part of an apparent contour.The authors focus their attention on the manipulation of apparent contours using a finite set of elementary moves, which correspond to diffeomorphic deformations of three dimensional scenes.A large part of the book is devoted to the algorithmic part, with implementations, experiments, and computed examples. The book is intended also as a user's guide to the software code appcontour, written for the manipulation of apparent contours and their invariants. This book is addressed to theoretical and applied scientists working in the field of mathematical models of image segmentation.
This book offers an updated review of malignant mesothelioma, including the latest advances in our understanding of its genetic control and molecular biology, as well as pre-clinical and clinical research. It also presents state-of-the-art diagnostic approaches and therapeutic options, and an open discussion on the future prospects for patient management.
Malignant mesothelioma is an enormous global health problem related to asbestos exposure. Despite the best efforts of scientists and oncologists, the prognosis for those affected remains poor. Due to anatomical characteristics and non-specific symptoms, the diagnosis of mesothelioma at an early stage is often difficult, while surgery and radiotherapy are only of limited use, even if some multimodality approaches seem promising. In turn, medical treatments are sometimes successful in tumor control, but have little impact on overall survival. However, advances in our understanding of the disease's biology, together with the availability of new drugs and combinations, make mesothelioma an essential and highly topical field for pre-clinical and clinical studies.
This book is subdivided into four parts: epidemiology and preclinical data, diagnosis, therapy, and extrathoracic mesothelioma. It highlights the progress made in a variety of areas - e.g. in vitro and in vivo experimental models, genetics, environment, biomarkers, targeting agents, immunotherapy, metabolic imaging and ongoing clinical trials - and describes the standard clinical management of mesothelioma patients, including those with extra-thoracic localizations. Given its scope, the book offers an invaluable tool for researchers, oncologists and clinicians alike.
