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>

This book covers all the existing imaging modalities currently in use in imaging departments, providing a sound basis for understanding how individual systems work. It is designed to be accessible to students without minimising the content. Although conventional imaging is being phased out, it still exists in certain areas, e.g. dental surgeries, and therefore is reduced in size and placed in an Appendix. The text has been restructured in list form to increase clarity and aid study Pedagogic features include an introduction and summary for each chapter Glossaries of imaging terms and computer buzz words, and a key to commonly used abbreviations are included New edition is completely rewritten: Digital imaging is main focus CT, ultrasound, MRI and NMR imaging added 'Conventional' imaging retained as an Appendix Text simplified, and block diagrams, flow charts and tables added to increase accessibility of content

This lively and entertaining manual on how to interpret abdominal radiographs will be invaluable to all medical students and junior doctors and has been written by a practising radiologist with many years' experience of teaching the subject. It outlines the few simple rules you need to follow, then explains how to sort out the initial and apparently overwhelming jumble of information which constitutes the abdominal X-ray. Knowledge of its contents will provide a secure base for tackling exams and the subsequent challenges of clinical practice. A comprehensive guide to all the common and serious conditions which are likely to be detected on a plain abdominal x-ray. Explains both how to look and what to look for on an abdominal film. Addresses exam technique to assist students preparing for clinical and OSCE exams. Fully updated including developments in the use of digital radiography and new legislation on radiation exposure. New additional illustrations of other complimentary forms of imaging such as the use of CT in suspected renal colic.

This book provides a concise introduction to the anatomy of the skeleton and to osteology. It gives a sound and comprehensive grounding in skeletal anatomy. Highly illustrated, with line diagrams, x-rays and CT and MR images, the text describes the principal anatomical features of the bones and the structure of the human skeleton.Each chapter is self-contained so the student can study them in any order, and lose no study time referring back to chapters for other references to a subject. This new edition has been extensively revised and, where necessary, the academic level has been upgraded to make it fully appropriate for degree level students as well as for trainee radiologists.

A thorough review of general mathematics and its applications in radiography as well as a handy reference for basic formulas and calculations used by radiographers. This book starts with basic mathematic principles and moves on to present the reader with the calculations required to produce high quality radiographic images and practice problems which aid in the understanding of these calculations. Areas discussed include mAs conversions, inverse square law, radiographic density and contrast, screens and grid ratios, grid conversions, geometric and magnification unsharpness, and graphs and conversions between conventional and systems international (SI) units of radiation dosimetry. No other book provides such clear instruction for radiographic calculations. A handy Instructor's Manual is also available.

'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).

This book reviews ionising radiation quantities and the relationships between them and discusses the principles underlying their measurement. The emphasis is on the determination of absorbed dose and related dosimetric quantities.
