Multislice Computed Tomography


Book Description

From the author of our best-selling handbook on helical (spiral) CT comes a brand-new, indispensable, practical guide to the next generation of technology--multislice (or multidetector) CT. Dr. Silverman and his renowned colleagues present detailed, easy-to-follow scanning protocols for all areas of the body, for pediatric examinations, and for three-dimensional imaging...and explain the principles behind the protocols. Multislice CT scanning protocols for specific clinical indications are presented in the same user-friendly outline format as in Dr. Silverman's other handbook. Representative images appear on the page opposite each protocol. The author's terminology allows the protocols to be used with equipment from any manufacturer.




MRI and CT of the Cardiovascular System


Book Description

Written by internationally eminent experts in cardiovascular imaging, this volume provides state-of-the-art information on the use of MRI and CT in the assessment of cardiac and vascular diseases. This third edition, now in four-color, reflects recent significant advances in cardiovascular MRI technology and the continuing emergence of multi-detector CT as an important diagnostic modality, particularly for ischemic heart disease. Seven new chapters have been added including chapters on anatomy, cardiovascular MR in infants/children, assessing myocardial viability, risk assessment in ischemic heart disease and MR guidance.




Protocols for Multislice Helical Computed Tomography


Book Description

Despite the expected decline in the mid-1970s in the use of computed tomography (CT) following the excitement of magnetic resonance imaging (MRI), CT has confounded its detractors and remains the imaging modality of choice, particularly for the chest and abdomen. Spiral/helical CT with the development of 64-multislice variant has revolutionized diagnostic imaging: image acquistion of large body volumes are obtained in short times during a single-breath hold. Scanning protocols without contrast enhancement are not a challenge; however, with intravenous contrast agents, critical choices are made and bad choices inevitably produce bad scans. This handy guide provides the reader with a simple introduction to the essential ideas involved and a practical guide to the implementation of rational scanning protocols for multislice spiral instruments. Written by Peter Dawson, a well-respected figure in computed tomography and radiology, and a world expert on contrast agents, Scanning Protocols for Multislice Helical Computed Tomography is an essential guide for all those working with CT, as well as those in training.




MDCT: A Practical Approach


Book Description

Computed Tomography


Book Description

The book offers a comprehensive and user-oriented description of the theoretical and technical system fundamentals of computed tomography (CT) for a wide readership, from conventional single-slice acquisitions to volume acquisition with multi-slice and cone-beam spiral CT. It covers in detail all characteristic parameters relevant for image quality and all performance features significant for clinical application. Readers will thus be informed how to use a CT system to an optimum depending on the different diagnostic requirements. This includes a detailed discussion about the dose required and about dose measurements as well as how to reduce dose in CT. All considerations pay special attention to spiral CT and to new developments towards advanced multi-slice and cone-beam CT. For the third edition most of the contents have been updated and latest topics like dual source CT, dual energy CT, flat detector CT and interventional CT have been added. The enclosed CD-ROM again offers copies of all figures in the book and attractive case studies, including many examples from the most recent 64-slice acquisitions, and interactive exercises for image viewing and manipulation. This book is intended for all those who work daily, regularly or even only occasionally with CT: physicians, radiographers, engineers, technicians and physicists. A glossary describes all the important technical terms in alphabetical order.

Multislice CT


Book Description

The introduction of multidetector spiral CT into clinical practice is without any doubt one of the most important technical developments in the field of computed tomography in general, and spiral CT in particular, in recent years. Indeed, multislice CT technology, based on the spiral CT technique invented by W. Kalender almost 20 years ago, has opened immense and totally new perspectives for better utilisation of contrast medium during the examination, for optimal multiplanar reconstruction and for increased patient throughput. The potential applications, more specifically in the area of CT angiography of the brain and the heart and vessels, are most interesting and definitely contribute to better patient care as well as to more effi cient utilisation of equipment. These exciting new clinical applications explain the keen desire of radiologists and other clinicians to hear and learn more about the first results obtained with this new equipment in daily clinical practice. This book will satisfy their needs. Professor Maximilian F. Reiser was among the first to install multidetector CT in his department in Munich and to gain experience with this new radiological tool. He was also able to organise a very successful and well attended international meeting on this hot topic as early as z 2000 in Starnberg, Germany.




Computed Tomography


Book Description

X-ray computed tomography (CT) continues to experience rapid growth, both in basic technology and new clinical applications. Seven years after its first edition, Computed Tomography: Principles, Design, Artifacts, and Recent Advancements, Second Edition, provides an overview of the evolution of CT, the mathematical and physical aspects of the technology, and the fundamentals of image reconstruction algorithms. Image display is examined from traditional methods used through the most recent advancements. Key performance indices, theories behind the measurement methodologies, and different measurement phantoms in image quality are discussed. The CT scanner is broken down into components to provide the reader with an understanding of their function, their latest advances, and their impact on the CT system. General descriptions and different categories of artifacts, their causes, and their corrections are considered at length. Given the high visibility and public awareness of the impact of x-ray radiation, the second edition features a new chapter on x-ray dose and presents different dose reduction techniques ranging from patient handling, optimal data acquisition, image reconstruction, and post-process. Based on the advancements over the past five years, the second edition added new sections on cone beam reconstruction algorithms, nonconventional helical acquisition and reconstruction, new reconstruction approaches, and dual-energy CT. Finally, new to this edition is a set of problems for each chapter, providing opportunities to enhance reader comprehension and practice the application of covered material.
