Clinical Cardiac CT: Anatomy and Function

CT of the Heart

During the past few years, cardiac CT CCT has acquired an increasingly important role as a noninvasive imaging method that allows assessment of coronary heart disease from both the morphological and the functional standpoint.

This book is a comprehensive and richly-illustrated guide to cardiac CT, its current state, applications, and future directions. While the first edition of this text focused on what was then a novel instrument looking for application, this edition comes at a time where a wealth of guideline-driven, robust, and beneficial clinical applications have evolved that are enabled by an enormous and ever growing field of technology. Accordingly, the focus of the text has shifted from a technology-centric to a more patient-centric appraisal.

Introduction

Cardiac computerized tomography CT has evolved from a research tool to an important diagnostic investigation in cardiology, and is now recommended in European, US, and UK guidelines. This review is designed to give the reader an overview of the current state of cardiac CT. The role of cardiac CT is multifaceted, and includes risk stratification, disease detection, coronary plaque quantification, defining congenital heart disease, planning for structural intervention, and, more recently, assessment of ischemia. This paper addresses basic principles as well as newer evidence. In the modern era, cardiac computerized tomography CT provides a robust non-invasive assessment of coronary artery disease CAD with a high degree of accuracy [ 1 , 2 ]. It is capable of providing anatomical information about plaque stenosis and composition, and is now recommended in national guidelines [ 3 — 5 ]. Its beginnings, however, were humble, and mainly of an exploratory nature.

This book is a comprehensive and richly-illustrated guide to cardiac CT, its current state, applications, and future directions. While the first edition of this text focused on what was then a novel instrument looking for application, this edition comes at a time where a wealth of guideline-driven, robust, and beneficial clinical applications have evolved that are enabled by an enormous and ever growing field of technology. Accordingly, the focus of the text has shifted from a technology-centric to a more patient-centric appraisal. While the specifications and capabilities of the CT system itself remain front and center as the basis for diagnostic success, much of the benefit derived from cardiac CT today comes from avant-garde technologies enabling enhanced visualization, quantitative imaging, and functional assessment, along with exciting deep learning, and artificial intelligence applications. Cardiac CT is no longer a mere tool for non-invasive coronary artery stenosis detection in the chest pain diagnostic algorithms; cardiac CT has proven its value for uses as diverse as personalized cardiovascular risk stratification, prediction, and management, diagnosing lesion-specific ischemia, guiding minimally invasive structural heart disease therapy, and planning cardiovascular surgery, among many others. This second edition is an authoritative guide and reference for both novices and experts in the medical imaging sciences who have an interest in cardiac CT.

Clinical Cardiac CT: Anatomy and Function

ECG-gated multislice CT provides a cost-effective, non-invasive technology for evaluation of the coronary arteries, as well as for additional clinical applications, which require morphological assessment of the heart and adjacent structures with simultaneous evaluation of the coronary circulation. The excellent negative predictive value of a normal coronary CTA cCTA examination excludes the presence of significant coronary disease in the symptomatic patient. Triple rule-out studies provide evaluation of the aorta and pulmonary arteries without loss of image quality in the coronary circulation. The ability to visualize surrounding vascular structures along with the coronary arteries is essential in the evaluation of coronary anomalies.

CT of the Heart

Technical developments have overcome the limitation of cardiac motion artifacts and made cardiac CT widely available. Coronary CT angiography CTA offers the tremendous benefit of obviating an invasive coronary angiography exam, specifically in patients with normal CTA results. With the additional features of functional cardiac and valvular assessment, and myocardial perfusion, CT has also become an alternative and complementary modality for specific questions traditionally reserved for cardiac ultrasound echocardiography or magnetic resonance imaging MRI.

He received his medical degree from the University of Ibadan, Nigeria. He is board-certified in Internal Medicine and Nuclear Cardiology. Since the advent of multislice computed tomography MSCT , remarkable technical advances have occurred. Arguably, 4-slice scanners have become obsolete, and slice systems may soon be considered antiquated with the arrival of faster slice technology. Improvements in spatial and temporal resolution have accompanied this rapid progress in technology, thus allowing for better visualization of coronary anatomy. This systematic review evaluates state-of-the-art cardiac MSCT in the diagnosis of coronary artery disease and discusses its performance relative to competing modalities.

About this book

Сьюзан покачала головой. Стратмор наморщил лоб и прикусил губу. Мысли его метались. Он, конечно, с легкостью мог набрать код лифта и отправить Сьюзан домой, но она нужна ему. Она должна помочь ему найти ключ в компьютере Хейла.

Мы вводим эту цитату. Сейчас. Джабба тяжко вздохнул. Он знал, что Фонтейн прав: у них нет иного выбора. Время на исходе. Джабба сел за монитор.
