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.

Book Description
Multislice technology has made it possible to investigate large sections of the human body in a very short time. The 4- and 16-row systems currently available necessitate the use of new protocols, which are proposed herein. In a convenient double-page layout, this book provides structured information on all routine protocols to be used for multislice CT. The volume covers all investigations of the brain, neck, lung and chest, abdomen and the periphery, as well as special protocols for the heart, for CT angiography and for CT-guided interventions. Each protocol is displayed en bloc, enabling rapid appreciation of the scanner settings and the indications.

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.

Book Description
This book provides structured up-to-date information on all routine protocols used for multislice (multidetector row) CT. The volume contains a detailed technical section and covers the prevailing investigations of the brain, neck, lungs and chest, abdomen with parenchymal organs and gastrointestinal tract, the musculoskeletal system and CTA as well as dedicated protocols for the heart. Separate chapters address the how-to of CT-guided interventions such as punctures, drainages, and therapeutic approaches. Each protocol is displayed en bloc, enabling rapid appreciation of indications and the necessary scanner settings. The second edition includes contributions by renowned experts in the field, who not only provide their clinical experience on each topic, but also give guidelines for indications, workflow, postprocessing and reconstruction algorithms.

Book Description
Until recently, CT scanner performance was limited by a series of compromises. With single-detector scanners, one cannot select thin collimation and still maintain the required extent of volumetric coverage. Slow scans cause motion artifacts that impair image quality. The introduction of multidetector CT technology, however, has revolutionized the field. Currently multidetector, multislice CT scanners acquire up to four channels of data from interweaving spirals. The minimum gantry rotation period is as low as half of a second. This increased scan speed allows for thinner collimation and thus higher longitudinal or z-axis resolution in comparison with single-detector CT. The improved image quality with multidetector technology leads to new applications of CT, particularly in cardiac, vascular, and abdominal imaging. On-going clinical studies are evaluating the suitability of this new imaging tool for non-invasive screening and diagnosis of coronary artery disease. A particular advantage to the increased scan speed in vascular imaging is the ability to cut intra venous contrast dosage and still maintain peak enhancement CT throughout the entire acquisition. Thin-section, multiphasic acquisition during optimal arterial-phase and venous-phase enhan cement significantly improves the accuracy for small lesion and vessel detection, and enhances overall classification of abdominal neoplasms. On the other hand, the increasingly large volume data sets force to new ways of looking at, presenting, storing, and trans ferring images. Networking and two- and three dimensional data processing are the key words.

Book Description
All you need to know to maximize the diagnostic capabilities of CT . . . Whole body computed tomography has developed at a rapid pace in the past decade, spurred on by the introduction of spiral and multislice scanning. These new technologies have not only improved diagnostic accuracy, but also made new applications possible that were previously accessible only through more complex or invasive techniques. This new book expertly fills a gap in the literature by combining the practically relevant technical background with the clinical information required for correctly performing and interpreting CT examinations. The book presents the state-of-the-art capabilities and requirements of CT as a key diagnostic and interventional tool, with special emphasis on the role of spiral and multi-slice CT. You will find a thorough introduction to CT technology from scanner design to 3D image reconstruction, useful practical hints on how to optimize your examination protocols and how to keep the radiation exposure of your patients to a minimum, as well as an extensive clinical section in which symptoms, pathology and CT morphology are integrated to provide you with the basis for subtle interpretation of CT findings using the most modern CT techniques. Highlights include: Full coverage of single-slice, 4-slice and 16-slice scanning techniques Introduction to extended CT applications including cardiac CT, CT fluoroscopy, and 3D image processing Organ-specific protocols for scanning and contrast administration Practical guidelines for maximizing image quality and minimizing radiation exposure Useful suggestions for image interpretation and for avoiding pitfalls and errors Convenient format by organ system and disease entity Full discussion of organ-specific pathology and CT morphology CT indications integrated with other imaging modalities At a time when CT examinations are becoming more technically demanding and complex, with an increasing number of scan parameters and advances in 3D reconstructions, this book is an essential professional tool. Experienced practitioners will find their diagnostic and technical skills improved by reading the book, and beginners will enjoy the clear, systematic approach that will help them use the technique with confidence.
