We have demonstrated the ability to identify coronary calcium using non-gated, 2-shot, dual energy (DE) chest x-ray imaging. Here we used digital simulations to characterize DE calcium signals and the role of potential confounds such as beam hardening, scatter estimation, cardiac motion, and pulmonary artery pulsation. For the DE calcium signal, we will consider quantification, as compared to CT calcium score. We created digital 3D phantoms including heart, lung, coronary calcium, spine, ribs, pulmonary artery, and adipose. We simulated x-ray acquisitions with x-ray spectra, energy dependent attenuation, scatter, ideal detector, and automatic exposure control (AEC). Phantoms allowed us to independently vary adipose thickness, cardiac motion, etc. to study the potential confounds. We used specialized dual energy coronary calcium (DECC) processing that includes corrections for scatter and beam hardening. Simulations indicate that proper DECC processing can faithfully recover coronary calcium signals. Potential confounds above are all manageable. Simulations are valuable as we continue to optimize DE coronary calcium image processing and quantitative analysis.

Background: Coronary artery disease is common in diabetic patients .In asymptomatic Diabetic patients, routine screening for coronary artery disease is not recommended as it does not improve outcomes as long as atherosclerotic cardiovascular disease risk factors are treated. It is better to stratify risk for high risk patients for better control of risk factors.Aim: Coronary calcium score for screening of coronary artery disease in asymptomatic diabetic patients.

This is the first monograph to focus exclusively on coronary radiology. It is particularly timely, given that the emergence of computed tomography and magnetic resonance imaging, coupled with improvements in both hard- and software, has made reproducible non-invasive coronary imaging a practical reality. A wide range of topics is addressed, including: quantitative angiography, intravascular and quantitative ultrasound, multislice and electron beam computed tomography, magnetic resonance coronary angiography and use of the coronary calcium score as an independent risk factor. All of the latest developments, such as non-invasive intracoronary thrombus imaging, are covered. Particular care has been taken to consider the common questions confronted in asymptomatic patients. The text is supported by high-quality color images of the coronary and cardiac anatomy.

CT is an accurate technique for assessing cardiac structure and function, but advances in computing power and scanning technology have resulted in increased popularity. It is useful in evaluating the myocardium, coronary arteries, pulmonary veins, thoracic aorta, pericardium, and cardiac masses; because of this and the speed at which scans can be performed, CT is even more attractive as a cost-effective and integral part of patient evaluation. This book collates all the current knowledge of cardiac CT and presents it in a clinically relevant and practical format appropriate for both cardiologists and radiologists. The images have been supplied by an experienced set of contributing authors and represent the full spectrum of cardiac CT. As increasing numbers have access to cardiac CT scanners, this book provides all the relevant information on this modality.

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. It is quickly becoming a primary clinical tool for the evaluation and follow-up of various conditions related to the heart and great vessels and is providing valuable insights into the natural history of atherosclerosis. The rapid advances in CCT technology, the advent of new clinical applications, and the acquisition of data on prognostic value are just some of the reasons for the publication of this new edition of Clinical Applications of Cardiac CT, little more than 3 years after the first edition appeared. The text has been extensively revised and updated to reflect current knowledge and practice, and the structure and layout of the educational content have also been improved. The imaging targets, semeiology, technique, and clinical applications of CCT are all covered in detail, and in addition relevant information is provided on epidemiology, clinical assessment, and the role of other diagnostic modalities. This book will prove an invaluable tool for radiologists and cardiologists alike.

In the intervening 10 years tremendous advances in the field of cardiac computed tomography have occurred. We now can legitimately claim that computed tomography angiography (CTA) of the coronary arteries is available. In the evaluation of patients with suspected coronary artery disease (CAD), many guidelines today consider CTA an alternative to stress testing. The use of CTA in primary prevention patients is more controversial in considering diagnostic test interpretation in populations with a low prevalence to disease. However the nuclear technique most frequently used by cardiologists is myocardial perfusion imaging (MPI). The combination of a nuclear camera with CTA allows for the attainment of coronary anatomic, cardiac function and MPI from one piece of equipment. PET/SPECT cameras can now assess perfusion, function, and metabolism. Assessing cardiac viability is now fairly routine with these enhancements to cardiac imaging. This issue is full of important information that every cardiologist needs to now.

Cardiac computed tomography (CT) has become a highly accurate diagnostic modality that continues to attract increasing attention. This extensively illustrated book aims to assist the reader in integrating cardiac CT into daily clinical practice, while also reviewing its current technical status and applications. Clear guidance is provided on the performance and interpretation of imaging using the latest technology, which offers greater coverage, better spatial resolution, and faster imaging while also providing functional information about cardiac diseases. The specific features of scanners from all four main vendors, including those that have only recently become available, are presented. Among the wide range of applications and issues discussed are coronary calcium scoring, coronary artery bypass grafts, stents, and anomalies, cardiac valves and function, congenital and acquired heart disease, and radiation exposure. Upcoming clinical uses of cardiac CT, such as hybrid imaging, preparation and follow-up after valve replacement, electrophysiology applications, myocardial perfusion and fractional flow reserve assessment, and plaque imaging, are also explored.

Stunning, Hibernation, and Calcium in Myocardial Ischemia and Reperfusion

Stunning is potentially an important complication of myocardial reperfusion. In contrast, hibernation is an important complication of myocardial ischemia. This book presents different viewpoints on these subjects, taken from a series of peer-reviewed articles which first appeared in Cardiovascular Drugs and Therapy, and now in this book. In addition, a certain number of articles were directly invited for the book. The introductory article is by Eugene Braunwald, who with Kloner introduced the term myocardial stunning in 1982. The experimental phenomenon had first been described by Heyndrickx et al. This important concept of stunning is examined from a number of points of view in a series of articles which clarify the experimental causes and the clinical implications. The section on hibernation is introduced by Tubau and Rahimtoola, the latter having first propounded the concept in 1989. The difference between stunning and hibernation is that stunning is essentially a post-ischemic dysfunction of the myocardium, temporary in nature, occurring at a time when coronary blood flow is apparently normal or supranormal. Hibernation, on the other hand, is a condition of reduced contractile activity, the direct result of chronic ischemia and hence a sign of a tolerable reduction in blood flow. Possibly the reduction in contractile activity of the hibernating heart balances the reduction in the oxygen availability (the `smart heart' of Rahimtoola). This non-contractile heart is hibernating, awaiting the return of summer after winter, and willing to contract normally again whenever warm coronary blood is restored. It is certain that the concepts of stunning and hibernation are here to stay, that they have or will have clinical relevance, and that the search for the most appropriate diagnosis and therapy for each condition is now under way. Hence, a greater understanding of the experimental work which underlies these two conditions is highly appropriate.
