With the advent of CT we entered a new area of radiological imaging. Structures which rarely if ever were seen became apparent. In no part of the body was the impact of CT as profound as it was in the retroperitoneum. In the pre-CT area this region of the body could not be directly studied and only when gross abnormalities were present could they be appreciated. The best we could do was to try to identify a suspected process by studying its effect on surrounding organs whose position might have been affected by the growth. Urography, barium studies or angiography were employed in the hope that variation in the position of the vessels, ureter or bowel would lead us to the correct diagnosis. With computed tomography all this changed. Modern scanners, available to all today, permit us to appreciate details undreamed of only few years ago. The abundance of fat in this region helps to clearly show even the smallest of structures. We now have the ability to recognize small vessels, lymph nodes and fascial planes. We had a tool which permitted us to study structures which hitherto were only seen by the anatomist or during surgical dissection.

This book provides a comprehensive and up-to-date overview of the continuously evolving field of dual-energy CT (DECT). An introductory section presents information on the physical and technical background of DECT and considers nonspecific and specific software advantages. Clinical applications of DECT in the evaluation of retroperitoneal viscera are then addressed in detail with the help of high-quality illustrations. Particular attention is devoted to the most recent DECT study protocols, software, and applications in aortic, renal, pancreatic, and adrenal disease. A number of case studies are reported that elucidate the advantages of DECT, and the relevant literature is extensively discussed. The book closes by considering radiation dose and dose-saving measures. The simple and practical approach offered by this book will assist radiologists in the optimal routine use and interpretation of DECT in different retroperitoneal sites and radiology technologists in the choice of settings and parameters.

Recent developments have favourably and extensively altered general surgical practice. As editor I have happily been able to select certain topics of new and major interest for detailed discussion and have thus had the opportunity to collect these authoritative submissions within the covers of one text. The range of topics is broad. Endoscopy has changed the nature of both investigation and treatment of much gastrointestinal disease and the therapeutic uses of endoscopy continue to grow. That sophisticated new tool of the radiologist, computerized axial tomography, has revolu tionized the diagnosis of intra-abdominal disease, very often permitting precise localization of hitherto occult disease, and, as might be expect ed, it has become helpful in determining both the nature and extent of surgical and other therapy. Although an invasive procedure, intra abdominal angiography has similarly come of age as a means of localiz ing gastrointestinal haemorrhage and controlling such bleeding. Unfortunately, intra-abdominal malignancy continues to be a major source of concern to the general surgeon and the discovery that such tumours are associated with unusual markers, termed oncofetal anti gens, suggests that early diagnosis and early detection of recurrence may yet be feasible. Adjuvant or post-surgical therapy is an exciting de velopment in terms of prolonging the disease-free interval in women with breast cancer limited to regional lymph nodes. Equally efficacious therapy is not yet available for patients with gastrointestinal cancer, highlighting the need for more specific drugs and drug combinations.

This book provides a comprehensive, state-of-the-art review of the diagnosis and management of retroperitoneal tumors. It highlights current surgical techniques for combined resection and reconstruction of various abdominal and pelvic organs and structures, along with adjuvant therapy. The book consists of three parts: Part 1 summarizes basic knowledge on retroperitoneal tumors and provides a detailed introduction to diagnosis and treatment, while Part 2 focuses on the surgical techniques used for retroperitoneal tumors and describes general procedures for operations on retroperitoneal tumors at different sites. Lastly, Part 3 details the etiology, pathology, evaluation, treatment and prognosis of retroperitoneal tumors according to pathological subtypes. This book is designed as a resource and guide for surgical and medical oncologists working with retroperitoneal tumors.

Developments in CT technology during the last 20 years have impressively improved its diagnostic potentialities. Part of a two-volume set that covers all aspects of CT imaging, Multi-Detector CT Imaging: Abdomen, Pelvis, and CAD Applications contains easily searchable clinical specialty chapters that provide specific information without need of an index. The coverage goes far beyond just a "how-to" or an encyclopedia of findings, however. The authors have uniformly put techniques, clinical findings, pathologic disease presentations, and clinical implications in practical perspective. It is no wonder that with the critical role CT plays and the rapid innovations in computer technology that advances in the capabilities and complexity of CT imaging continue to evolve. While information about these developments may be scattered about in journals and other resources, this two-volume set provides an authoritative, up-to-date, and educational reference that covets the entire spectrum of CT.
