Genre: Medical

Dual-energy CT is a novel, rapidly emerging imaging technique which offers important new functional and specific information. In this book, physicists and specialists from different CT manufacturers provide an insight into the technological basis of, and the different approaches to, dual-energy CT. Renowned medical scientists in the field explain the pathophysiological and molecular background of the technique, discuss its applications, provide detailed advice on how to obtain optimal results, and offer hints regarding clinical interpretation. The main focus is on the use of dual-energy CT in daily clinical practice, and individual sections are devoted to imaging of the vascular system, the thorax, the abdomen, and the extremities. Evaluations and recommendations are based on personal experience and peer-reviewed literature. Plenty of carefully chosen high-quality images are included to illustrate the clinical benefits of the technique.

Brain CT Scans in Clinical Practice

Release Date: 2009-04-28
Genre: Medical

Across emergency rooms all over the world, thousands of patients are referred for brain CT scans daily. A radiologist often has to interpret the scan or a consultation has to be made to a neuros- geon to review the scan. Most of this happens late at night and is a signi?cant source of discontent. Thus having frontline phy- cians to be pro?cient in interpreting the emergency brain CT scan improves the ef?ciency of the whole pathway of care and is pot- tially life saving as time is of the essence for many patients with severe brain injury or stroke. Underlying all of the above and the primary reason for writing this book is because the skill required to determine an immediate life threatening abnormality in a brain CT scan is so basic and can be learned in a short time by people of various backgrounds and certainly by all physicians. ‘Indeed the emergency head CT scan is comparable to an electrocardiogram in usefulness and most de?nitely as easy to learn. ’ This book is therefore written for ca- givers the world over to demystify the emergency CT brain scan and to empower them to serve their patients better. It is obvious to me from the response from people I have had opportunity to teach this subject that not only is there a desire to learn this basic skill but also people learn it quickly and wonder why it has not been presented so simply before.

Dual Energy CT in Oncology

Author: Carlo N. De Cecco
Publisher: Springer
ISBN: 9783319195636
Release Date: 2015-08-19
Genre: Medical

The aim of this book is fourfold: to describe the basic principles of Dual Energy CT (DECT) imaging, to explain how post-processing is utilized, to critically appraise the strengths and weaknesses of the technique in oncologic imaging, and above all, to demonstrate the contribution of DECT in the management of oncologic patients. Information is provided on the practice and interpretation of DECT and its impact on clinical decision making in a variety of oncological settings, including tumors of the head and neck, lung, liver, pancreas, gastrointestinal system, kidney, and musculoskeletal system. DECT is an innovative imaging technique in which the application of two distinct energy settings provides a transition from density-based image to spectral imaging. As detailed in this book, DECT acquisition allows the simultaneous generation of multiple datasets which enable the radiologist to address varied diagnostic problems in oncologic imaging using a multiparametric approach, having clear advantages in tumor detection, lesion characterization and evaluation of treatment response.

Dual Energy CT in Cardiovascular Imaging

Author: Patricia M. Carrascosa
Publisher: Springer
ISBN: 9783319212272
Release Date: 2015-10-03
Genre: Medical

This is the first textbook in DECT focussing especially on the cardiovascular field. DECT was developed many years ago but has recently spread its clinical utility. Many new applications have been developed over the last years and the cardiovascular system has benefited from these advances. New protocols will be used in the near future which will help to optimize results obtained until now with single energy CT, such as a more precise quantification of coronary artery stenosis using either different monochromatic levels or material decomposition, reduction of beam hardening artifacts in perfusion studies and optimizing endovenous contrast, among others.​

Publisher: Society of Photo Optical
ISBN: 0819492574
Release Date: 2012-01-01
Genre: Science

Computed tomography (CT) is a widely used x-ray scanning technique. In its prominent use as a medical imaging device, CT serves as a workhorse in many clinical settings throughout the world. It provides answers to urgent diagnostic tasks such as oncology tumor staging, acute stroke analysis, or radiation therapy planning. Spectral Computed Tomography provides a concise, practical coverage of this important medical tool. The first chapter considers the main clinical motivations for spectral CT applications. In Chapter 2, the measurement properties of spectral CT systems are described. Chapter 3 provides an overview of the current state of research on spectral CT algorithms. Based on this overview, the technical realization of spectral CT systems is evaluated in Chapter 4. Device approaches such as DSCT, kV switching, and energy-resolving detectors are compared. Finally, Chapter 5 summarizes various algorithms for spectral CT reconstructions and spectral CT image postprocessing, and links these algorithms to clinical use cases
