Nuclear cardiac imaging refers to cardiac radiological diagnostic techniques performed with the aid of radiopharmaceuticals, which are perfused into the myocardium as markers. These imaging studies provide a wide range of information about the heart, including the contractility of the heart, the amount of blood supply to the heart and whether parts of the heart muscle are alive or dead. This is essential information for cardiologists, and nuclear imaging has become an increasingly important part of the cardiologist's armamentarium. Chapters in Nuclear Cardiac Imaging cover historical, technical and physiological considerations, diagnosis and prognosis, conditions other than Coronary Artery Disease (CAD), advanced cardiac imaging, and challenges and opportunities. New to the sixth edition are key point summaries at the start of each chapter, clinical cases with videos, and a question and answer chapter on practical issues. This volume is ideal for nuclear cardiologists in training and nuclear clinicians alike who are searching for quick answers to important clinical and technical questions.

A companion to the 6th edition of Nuclear Cardiac Imaging, this text offers readers additional case examples and figures not included in the related textbook as well as a concise option for readers seeking a case book for quick review for examination preparation or assistance with image interpretation. Rather than focusing on theoretical explanations, the atlas provides high-yield, rapid imaging support with a particular emphasis on cases with angiography, echocardiography, and other imaging correlations. With a variety of cases and multiple-choice self-assessment questions along with a comprehensive multiple-choice exam to be taken upon completion of the text, the Companion Atlas will solidify readers' knowledge and ranges in levels of difficulty, including those intended to challenge even the most expert reader.

In the past few years it has become clear that left ventricular dysfunction, even of severe degree, may be reversible after coronary revascularization in some patients. As a result, myocardial viability has captured the imagination of researchers and clinicians seeking to unravel the cellular and subcellular mechanisms and define appropriate diagnostic modalities. These diagnostic modalities include: cardiac catheterization, positron-emission tomography, magnetic resonance imaging, two-dimensional echocardiography and single-photon imaging. This book brings together a diverse array of information in a comprehensive and concise fashion using a template of 10 chapters written by experts in the field. It should be of value to cardiologists, radiologists, nuclear medicine specialists, cardiac surgeons, anesthesiologists, internists and basic researchers and their trainees who are involved in the management of patients with coronary artery disease in whom myocardial viability is a clinically relevant issue.

Performing any diagnostic test in medicine is always a matter of trying to get the condition of the patient diagnosed properly with the least effort, exposure, discomfort and at the same time with the lowest possible error probability.Pre-test probability is helpful but often imprecise, effectively overestimating the patient's risk profile. In a broader prevention objective, the phases of a disease, its onset, progression, and complications must be taken into account. The negative predictive value, which is so important, has in turn its main limitation in identifying the healthy patient, that is, the one who does not belong to any cluster of patients in which we would act in terms of prevention.In coronary syndromes, the goal is instead to evaluate coronary heart disease, from mild to more extensive and significant forms. For this purpose, it is necessary to use parameters that investigate different and complementary aspects: stenosis, ischemia, the morphology ofthe atherosclerotic plaque, metabolic processes, in particular vitality and apoptosis, the presence of inflammatory processes.The possibility, already present thanks to Hybrid Imaging, of 'joining’ exams that study different aspects, will allow the patient to be increasingly characterized not only from a diagnostic point of view but also from a prognostic and personalized therapeutic choice.
