Ct Colonography

In CT Colonography, Perry Pickhardt and David Kim present techniques for quicker evaluation and diagnosis of colon cancer through the pioneering, specialty-changing imaging technique of virtual colonoscopy (VC). This combination of sophisticated X-rays and CT scans of the abdomen offers patients an alternative to colonoscopy that is cost effective and reduces the need for unnecessary polyp removal. Abundantly illustrated in full color, this pioneering book describes CT colonography from pathogenesis, staging and treatment through indications, technique, and interpretation for the most common pathologies. Covers principles, techniques, and interpretations for the most common pathologies in a logical, practical organization. Presents tips from the authors on setting up a VC practice to provide a personal, instructive guide. Provides over 1000 full-color, high-resolution anatomic images throughout for the clearest, most accurate picture of colorectal cancer, its natural history, and its diagnosis by VC. Focuses on images, with the text serving as context for the proper use and understanding of VC.

Highly effective as a minimally invasive diagnostic and screening tool, CT colonography (CTC) is an important part of today's clinical armamentarium. In this concise, step-by-step guidebook, written by specialists who also run training courses in CT colonography, readers will find a wealth of information for everyday practice. From examination methods and image interpretation, to screening and reporting issues, to common mistakes and pitfalls to avoid, this compact book is all-inclusive, ideal for both beginners and more experienced examiners who want to deepen their knowledge of this powerful technique. Special Features: Full discussion of how to begin, including indications and contraindications, patient preparation, CT examination techniques, and patient risk profile Strategies for data analysis and clinical interpretation, including 2D and 3D applications ("virtual" visualization), polyp measurement, and computer-assisted detection of polyps Informative, point-by-point sections on clinical findings, starting with normal anatomy of the colon and moving on to common diseases, postoperative conditions, pitfalls and artifacts, and incidental extracolonic findings More than 500 top-quality, fully labeled illustrations (245 in full color), including normal CT scans and 2D and 3D reconstructions that demonstrate diagnostic criteria, possible differential diagnoses, and disease states Guidelines for standardizing reports and documenting findings Tips on how to train for CT colonography in your clinical practice With all methods and techniques following current international guidelines and consensus statements, this book offers easy-to-implement, standardized clinical protocols that can be applied in both the clinic and the out-patient setting. It is essential for all radiologists and gastroenterologists who are interested in learning about the fundamentals of CT colonography and how to interpret and report findings, as well as for physicians who need a reliable overview of this robust and useful detection and screening tool.

This open access book deals with imaging of the abdomen and pelvis, an area that has seen considerable advances over the past several years, driven by clinical as well as technological developments. The respective chapters, written by internationally respected experts in their fields, focus on imaging diagnosis and interventional therapies in abdominal and pelvic disease; they cover all relevant imaging modalities, including magnetic resonance imaging, computed tomography, and positron emission tomography. As such, the book offers a comprehensive review of the state of the art in imaging of the abdomen and pelvis. It will be of interest to general radiologists, radiology residents, interventional radiologists, and clinicians from other specialties who want to update their knowledge in this area.

This second edition, comprising 28 chapters, explains every aspect of the role of radiographers in performing CT colonography (CTC) and interpreting CTC images with the aim of enabling radiographers to extend the scope of their practice. It provides information required with respect to communication with the patient, procurement of informed consent, the principles of CT as well as dual-energy CT and photon counting CT, radiation dose, patient preparation and positioning, the use of contrast media, the performance of diagnostic and screening CTC studies, the interpretation and reporting of images, legal and professional requirements, and the importance of clinical audits. A wide range of CTC findings is described and depicted, covering normal anatomy, artefacts, haemorrhoids, polyps, colon cancer, diverticular disease, lipomas, extracolonic structures, opportunistic screening for osteoporosis and metabolic associated fatty disease, and CTC in incomplete or failed colonoscopy. The role of other modalities such as ultrasound, magnetic resonance imaging, and nuclear medicine in colorectal cancer patients is discussed. In addition, the text covers the role of artificial intelligence and machine learning in imaging of the colon for the detection of polyps, diagnosis and staging of colorectal cancer. Lastly, a chapter focusing on self-assessment of image interpretation will aid learning. This book provides the support that radiographers need in order to perform CTC studies to the standard required in terms of advances in imaging and interpretation of images.

This easy-to-use atlas comprises a collection of representative common and unusual virtual colonoscopy (CT colonography, CTC) cases that physicians and radiologists may expect to encounter during their clinical practice. The atlas reflects the important recent advances in image acquisition, patient preparation, and image processing and is thus completely up-to-date. Each case is presented with the native CT images, integrated images obtained by 3D image processing, and colonoscopic correlation. Topics covered include normal appearances, anatomical variants, pitfalls, diverticula, lipomas, inflammatory bowel disease, polyps, flat lesions, cancers, and the postsurgical colon. By presenting the main features of anatomy and pathology, this atlas will serve as an invaluable tool both for radiologists performing CTC and for clinicians who need to review the CTC examinations of their patients.
