For over 50 years, coronary angiography has been the mainstay of diagnosing and quantifying the extent of coronary artery disease. However appreciation of the inherent limitations of conventional angiography has led to a plethora of new imaging modalities, each with their relative strengths and potential pitfalls. Advances in these techniques have given clinicians, as well as researchers, an overwhelming amount of information and the need for thoughtful interpretation. This outstanding book provides a comprehensive overview of the current status of imaging of coronary atherosclerosis. Covering the wide variety of available imaging modalities, the book provides state-of-the-art knowledge from leading authorities in each area. In their discussion, the authors include both invasive and non-invasive modalities, including the gold standard coronary angiography, the growing field of IVUS, and novel techniques such as functional imaging, molecular imaging, and the integration of biomarkers. The key concepts and practical information given in this volume will provide the reader with the necessary understanding to choosing appropriate imaging studies and building confidence in their skill set with each.

Atherosclerosis is a disease which has impacted our health like no other in the last half century. The detection of this disease range from biomarkers, stress-testing to invasive imaging by way of angiography or other intravascular methods. In recent years, technological developments in multi-detector computed tomography (MDCT) and magnetic resonance imaging (MRI) has allowed us to visualize atherosclerotic plaque noninvasively. This has great appeal as they carry very little risk in comparison to invasive angiography and provide information of plaque composition in addition to stenosis severity. The identification of plaques which are high-risk or 'vulnerable' to subsequent complications such as myocardial infarction or stroke would be highly valuable in our approach to incremental risk assessment and perhaps future treatment. Certain procedures in interventional cardiology such as saphenous vein graft (SVG) intervention and carotid stenting carry increased risk of embolic complications compared to coronary stenting. Non-invasive imaging could potentially identify certain plaque features which may be associated with an increased risk of embolization before embarking on such procedures. This thesis examines the utility of MDCT and MRI in atherosclerotic plaque imaging prior to SVG interventions and carotid stenting. Our initial chapter investigates the angiographic parameters associated with embolization during SVG intervention. We correlate the amount of debris captured by distal protection devices during intervention with angiographic markers and subsequently, with impaired blood flow by way of Thrombolysis In Myocardial Infarction (TIMI) frame count. Our next step involved the accuracy and reproducibility of MDCT and MRI in plaque quantification in comparison to our reference standard of intravascular ultrasound. We measured the luminal, vessel wall and plaque areas, and then calculated the resultant plaque volume of SVG lesions for all three modalities. Having gained an understanding of the accuracy of MDCT and MRI, we investigated the relationships of MDCT plaque volume and density with embolic debris captured by distal protection device during SVG intervention. We then undertook histological assessment of the debris utilizing semi-automated image analysis software. We quantified the various plaque components including red blood cells, thrombus, lipid, cholesterol clefts and fibrous tissue. Finally, we explored the relationship between the histological findings with plaque volume, density and amount of embolization which occurred. Our last original chapter investigates the utility of multi-weighted MRI to assess carotid plaque prior to stenting. We measured plaque volumes and characterized plaques as calcific, fibrotic or lipidic according to MRI findings. This information is then correlated to the amount of embolic debris captured by the distal protection device used during stenting. In comparison to invasive imaging modalities like intravascular ultrasound, research into plaque characterization by MDCT and MRI is just beginning. Almost all of the current studies have been on coronary artery plaques. This thesis breaks new ground by studying SVG plaques and demonstrating links between plaque volume, composition and embolization during intervention. It builds on our knowledge of these non-invasive modalities and help us define their future roles.

The philosophy of this NATO Advanced Research Workshop and the monograph it has yielded is that if you put a small number of very talented and creative scientists of different backgrounds and documented accomplishments together in a cloistered place for a few days to consider a very important and timely topic, many new ideas will be generated. The keynote of this conference was the Future. By this we mean the expected future developments of highly reliable sequential quantitative measurements of atherosclerotic plaque size and components in living human subjects. Some of the best minds and the most experienced and talented individuals at the leading edges of imaging of arteries were involved; some of the best scientists and students of the atherosclerotic plaque and its components participated; and some of the leading investigators of the cell biology or, as we call it in the USA, the pathobiology of atherosclerosis, contributed important new information. All of these individuals were actively involved in the conference and each obviously had carefully prepared and was able to communicate effectively.

Recent years have seen a marked increase in cardiovascular computed tomography (CT) imaging, with the technique now integrated into many imaging guidelines, such as those published by ESC and NICE. Rapid clinical and technological progress has created a need for guidance on the practical aspects of CT image acquisition, analysis and interpretation. The Oxford Specialist Handbook of Cardiovascular CT, now revised for the second edition by practising international experts with many years of hands-on experience, is designed to fulfil this need. The Handbook is a practical guide on performing, analysing and interpreting cardiovascular CT scans, covering all aspects from patient safety to optimal image acquisition to differential diagnoses of tricky images. It takes an international approach to both accreditation and certification, highlighting British, European, and American examinations and courses. The format is designed to be accessible and is laid out in easy to navigate sections. It is meant as a quick-reference guide, to live near the CT scanner, workstation, or on the office shelf. The Handbook is aimed at all cardiovascular CT users (Cardiologists, Radiologists and Radiographers), particularly those new to cardiovascular CT, although even the advanced user should find useful tips and tricks within.

This book provides comprehensive information on new and existing vessel imaging techniques, with the intention of improving diagnosis, treatment, and prevention of vascular and related diseases. In recent years, vessel wall imaging has expanded greatly into other beds (such as the intracranial and peripheral arteries) and many of the techniques available for evaluation and diagnosis have only previously been published in research papers. This book bridges that gap for clinicians, applying cutting edge research to their everyday practice. The first six sections of the book are centered around individual vessel beds. These chapters will teach clinicians the multi-modality imaging techniques available to image these vessels and related pathology with a focus on new imaging tools and techniques. The final two sections of the book will offer a more comprehensive technical background aimed at imaging scientists for the imaging techniques used and the relationship of blood flow and modeling to disease monitoring and prevention. This is an ideal guide for radiologists and imaging scientists looking to learn the latest techniques in vessel imaging.
