The last decade has seen enormous upheaval within all aspects of health care, and the gastrointestinal/ gastroenterology (GI) service has been no exception. Increasing demand for new and established diagnostic and interventional procedures has encouraged innovative models of service delivery, resulting in a range of health professionals crossing traditional practice boundaries. In particular, nurses and radiographers have seized the opportunity to develop their scope of practice, managing a range of procedures including colonoscopy, barium studies and CT colonography. This has, in many cases, freed both radiologists and gastroenterologists to take on new roles in the interventional service. The development of new procedures and new ways of working has promoted a renewed enthusiasm for critical evaluation of the GI service as a whole. As practitioners and clinicians learn new skills and extend their scope of practice it is essential that they have a thorough understanding of the basis of safe, effective and evidence based practice. This book offers the reader a detailed overview of the range of imaging procedures that may be employed in the investigation of gastrointestinal tract pathology, and explores current practice related to the subsequent patient care pathways and treatment options. It has been designed as a detailed reference guide for all health professionals who have a direct involvement in the GI tract and its imaging, including those who may be referring patients for GI radiological investigation, those professionals who are performing and subsequently reporting the procedures, and the clinicians responsible for the subsequent patient management. This book offers a unique insight into the rapidly changing radiology service, and offers introductory chapters which provide the fundamental underpinning knowledge required for safe and effective GI practice. Subsequent chapters discuss the evidence base related to a range of imaging procedures suitable for investigation of upper and lower GI symptoms, supported by key pathology chapters. The book also explores the range of treatments available for the more common GI tract pathology. Multi professional authorship. Detailed evidence-informed explanations of a range of individual GI procedures, including suggestions for problem solving and adaptation of technique. With extensive illustrations, medical images, boxes and tables. References and further reading. /ul>

The articles collected in this volume are based on lectures given at the IMA Workshop, "Computational Radiology and Imaging: Therapy and Diagnostics," March 17-21, 1997. Introductory articles by the editors have been added. The focus is on inverse problems involving electromagnetic radiation and particle beams, with applications to X-ray tomography, nuclear medicine, near-infrared imaging, microwave imaging, electron microscopy, and radiation therapy planning. Mathematical and computational tools and models which play important roles in this volume include the X-ray transform and other integral transforms, the linear Boltzmann equation and, for near-infrared imaging, its diffusion approximation, iterative methods for large linear and non-linear least-squares problems, iterative methods for linear feasibility problems, and optimization methods. The volume is intended not only for mathematical scientists and engineers working on these and related problems, but also for non-specialists. It contains much introductory expository material, and a large number of references. Many unsolved computational and mathematical problems of substantial practical importance are pointed out.

'Understanding X-Rays' is a book planned to fill the gap between basic and advanced knowledge of Radiology.It meets the moment when a - diologist is not available, and a diagnosis is required. Each section is introduced by a chapter on 'how to 'understand'X-rays', encouraging a complete and systematic approach to radiographs focusing on every part of the image.A three-point approach is presented, consi- ing of the 'quick look', a systematic detailed scrutiny of the images, and - nally a brief look at 'review areas'. Most difficulties in interpreting radiographs do not arise from iden- fying the clearly normal or abnormal, but the huge grey expanse between. Therefore, normal variants that may masquerade as disease are discussed in detail.Likewise, common appearances, often incidental and unimp- tant, are covered thoroughly, as these appearances can readily be misint- preted as being due to significant disease. The chapters on disease entities follow a logical sequence of conge- tal, traumatic, infective, neoplastic and miscellaneous conditions. Po- traumatic sequelae are discussed in much greater detail in each section. To limit the handbook to a pocket-sized format, certain aspects of Radi- ogy receive scant attention and some are excluded altogether.(The foll- ing are not included: physics, instrumentation, machine construction, - teriography, and ultrasound imaging of obstetrics, the eye and vascular structures.Aspects such as congenital heart disease, bone dysplasias, bone tumours and barium meal examinations are not discussed at any length).

To continue the support for the growing trend of chemistry involvement in nuclear medicine, the Division of Nuclear Chemistry and Technology (DNCT) of the American Chemical Society (ACS) planned for a symposium to cover this aspect. This was expressed in arequest to me, as a member of the Program Committee, to organize a symposium on topics related to nuclear and radiochemistry applications to nuclear medicine. Realizing the growing interest in imaging, specially with positron emitting radioisotopes, I invited several colleagues to study with me the idea of imaging centers and the involvement of chemists in their structure and function. The formulated Organizing Committee supported this idea which evolved in proposing an extended international symposium to be held in conjunction with the 206th ACS National meeting in Chicago, Illinois, U. S. A. on August 22-27, 1993. The following are the members of the Organizing Committee: Jorge R. Barrio, Ph. D. Thomas E. Boothe, Ph. D. J. Robert Dahl, Ph. D. Robert F. Dannals, Ph. D. Bruce R. Erdal, Ph. D. Mark M. Goodman, Ph. D. George W. Kabalka, Ph. D. James F. Lamb, Ph. D. Ronald G. Manning, Ph. D. Henry C. Padgett, Ph. D. Roy S. Tilbury, Ph. D. Steven W. Yates, Ph. D. and Ali M. Emran, Ph. D.

This book documents the fascinating history of radiological techniques that use contrast agents. The text includes many of the fundamental documentary sources that bring to life the social and scientific background of the discoveries, the personalities of the discoverers, and implementation of new technologies. Such agents when used with X-rays allow clinicians to distinguish anatomical structures with nearly identical densities. Focus is on urological and angiographic uses of contrast agents. Key selling features: Documents and thoroughly references the history of contrast agent development Reviews the priority and importance of patents Discusses the role that important individual scientists and leading research institutions have played in technology development and implementation
