Book excerpt: Ischemic heart disease (IHD) is the main cause of morbidity and mortality in the developed world. Despite advances and new developments in primary and secondary prevention, the prevalence of the disease and its complications remain high. Early detection has been shown to reduce significantly the risk of cardiac events such as myocardial infarction and death, while modern cardiology now provides specialists and general physicians with a variety of procedures for the assessment of IHD using noninvasive methods. This book reviews the currently available imaging techniques for the diagnosis and management of IHD. In addition, the role of cardiac imaging for the detection of viability and hibernation is discussed in detail.

Download or read book Integrated Non Invasive Cardiovascular Imaging A Guide for the Practitioner written by IAEA and published by International Atomic Energy Agency. This book was released on 2021-06-14 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated cardiovascular imaging is the optimal use of multiple imaging modalities to obtain complementary information about cardiac diseases, to aid in diagnosis, determine aetiology and prognosis, with the ultimate objective of effectively guiding clinical decision making. Over the past few decades, advances in technology have contributed to the development of new imaging modalities and refinement of existing ones, leading to major improvements in the accuracy of diagnosing cardiovascular disease. While modality-centric expertise has been the primary driver of improvements in each modality, this has also contributed to imagers working in silos resulting with limited inter-modality coordination and collation of information relevant for patient care. This publication provides comprehensive guidance on the rationale and implementation of integrated cardiovascular imaging for practitioners.

Download or read book Advances in Imaging Techniques in Ischemic Heart Disease written by Ernst E. van der Wall and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years there have been tremendous advances in cardiac imaging techniques covering the complete spectrum from echocardiography, nuclear cardiology, magnetic resonance imaging to contrast angiography. With respect to these noninvasive and invasive cardiac imaging modalities, marked technological developments have allowed the cardiologist to visualize the myocardium in a far more refined manner than conventional imaging was capable of. Echocardiography has extended its domain with intravascular ultrasound, cardiovascular nuclear imaging has added positron emission tomography to its line of research, magnetic resonance imaging has been broadened with magnetic resonance angiography and spectroscopy, and finally contrast angiograp hy has widened its scope with excellent quantitation programs. For all these imaging modalities it is true that the application of dedicated quantitative analytic software packages enables the evaluation of the imaging studies in a more accurate, reliable, and reproducible manner. It goes without saying that these extensions and achievements have resulted in improved diagnostics and subsequently in improved patient care. Particularly in patients with ischemic heart disease, major progress has been made to detect coronary artery disease in an early phase of the disease process, to follow the atherosclerotic changes in the coronary arteries, to establish the functional and metabolic consequences of the luminal obstructions, and to accurately assess the results of interventional therapy.
Download or read book Noninvasive Imaging of Hemorrhagic Myocardial Infarction with Confounder Corrected T2 Cardiac MRI written by Xingmin Guan and published by . This book was released on 2022 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: The current gold-standard approach for detection and quantification of intramyocardial hemorrhage (IMH) is T2* cardiovascular magnetic resonance imaging (CMR). T2*-based imaging techniques have been demonstrated to have high sensitivity for detecting hemorrhage and residual iron. The conventional T2*-based imaging employed for IMH imaging is based on a 2D breath-held, ECG-triggered, segmented, multi-gradient-echo sequence. More recently, a dark-blood cardiac T2* MRI technique has emerged for imaging of global iron overload such as thalassemia. It has been interchangeably used with bright-blood T2* MRI for imaging of local iron overload such as intramyocardial hemorrhage. To date however, dark-blood T2* techniques for intramyocardial hemorrhage characterization has not been validated. In Chapters 2 and 3, we investigated the diagnostic capacity of dark-blood T2* MRI against bright-blood T2* MRI for intramyocardial hemorrhage characterization in both clinical and preclinical settings. We found that double-inversion-recovery prepared dark-blood T2* images provide lower signal-to-noise ratio and lower contrast-to-noise ratio between hemorrhage and remote myocardium, consequently underestimating the hemorrhage extent. Dark-blood T2* MRI also demonstrated weaker sensitivity, specificity, accuracy, and inter-observer variability compared to bright-blood T2*-weighted MRI. Our studies also showed that the loss in SNR and CNR in dark-blood T2* imaging emerges from the signal loss following double-inversion-recovery preparation and insufficient recovery time between double-inversion-recovery preparation and readout. Hence, we conclude that dark-blood T2* MRI does not have the same diagnostic capacity for assessment of intramyocardial hemorrhage and bright-blood T2* MRI should be the preferred choice for clinical use. Studies have shown that fat infiltration is a common phenomenon in chronic myocardial infarction. However, signal from fat protons can confound the T2* assessment of intramyocardial hemorrhage. To address this issue, in Chapter 4, we studied the influence of fat infiltration on iron quantification in T2* mapping using a widely accepted water-fat separation algorithm. Specifically, we evaluated the temporal dependence of fat infiltration in hemorrhagic myocardial infarctions. We found that fat infiltration was observed in early and late chronic phases of myocardial infarctions, which if not corrected for, can underestimate the extent of iron content within the infarct zone. Notably, we also found that the amount of fat infiltration in chronic phase of MI was closely correlated with the amount of iron. Another major confounder in conventional 2D breath-held ECG-gated T2* imaging is motion artifacts. In clinical settings, patients with acute myocardial infarctions often find it difficult to hold their breath during cardiac MRI exams. Some patients may even suffer from arrhythmia (irregular heartbeat). Both situations can lead to unsuccessful gating during data acquisition leading to motion artifacts on T2* images especially with long echo times. To address this issue, in Chapter 5, we developed a motion-resolved fully ungated free-breathing 3D cardiac T2* imaging technique using a low-rank tensor framework to accommodate clinical needs and to mitigate motion artifacts due to unsuccessful breath-holds or ECG gating. We tested our 3D LRT technique in healthy volunteers and animal models for image quality, SNR and T2*. We found that the proposed 3D LRT technique can provide superior image quality compared to conventional T2* techniques at the same level of signal-to-noise ratio. T2* measured from proposed 3D LRT data showed excellent agreement with T2* from conventional 2D approach. We also found that a key benefit of 3D acquisition is that it permits the reconstruction of high-resolution T2* images using the proposed 3D LRT T2* approach. High-resolution T2* images from proposed 3D LRT approach showed superior image quality and diagnostic capacity for assessment of intramyocardial hemorrhage. In Chapter 6, the proposed 3D LRT T2* imaging approach was validated on an animal model for feasibility and capability for characterization of intramyocardial hemorrhage. We found that our 3D LRT approach had excellent image quality and diagnostic accuracy in the assessment of intramyocardial hemorrhage compared to the 2D breath-held and gated acquisitions. Broadly, this dissertation identified and corrected a number of critical confounders affecting the accuracy of T2* MRI in assessment of intramyocardial hemorrhage. By identifying and solving these confounders in T2* imaging, we aim to improve the diagnostic capability of MRI for prognosis and therapeutic care of patients with hemorrhagic myocardial infarctions. In future work, feasibility of the newly developed fully ungated free-breathing 3D LRT T2* imaging technique will be investigated on patients for imaging of intramyocardial hemorrhage. And the potential of high-resolution T2* imaging which greatly improved intravoxel dephasing due to off-resonance will be explored.

Book excerpt: This is the seventh edition of a long-selling book (first edition 1991) that was translated into Italian, French, Chinese, Portuguese, Spanish, English. In the last ten years, stress echocardiography has exploded in its breadth and variety of applications. From a one-fits-all approach (wall motion by 2D-echo in the patient with known or suspected coronary artery disease), the field has progressed to an omnivorous, next-generation laboratory employing a variety of technologies (from M-Mode to 2D, from pulsed, continuous, color and tissue Doppler to lung ultrasound) on patients covering the entire spectrum of severity (from elite athletes to patients with end-stage heart failure) and ages (from children with congenital heart disease to the elderly with aortic stenosis). This new edition is enriched with over 300 figures, 150 tables and video-clips. In a societal and economic climate of increasing pressure for appropriate, justified and optimized imaging, stress echocardiography offers the great advantages of being radiation-free, relatively low cost, with minimal environmental impact, and with a staggering versatility: we can get more (information) with less (cost and risk). The volume will be a tremendous aid to current best practices for all health operators who intend to use stress echocardiography and ultrasound for diagnosis and guidance of optimal management in their patients.
Download or read book Myocardial Viability written by Vasken Dilsizian and published by Wiley-Blackwell. This book was released on 2000-02-10 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite remarkable advances in the understanding and management of impaired left ventricular function (LVF) and related coronary disease, the prevalence of heart failure in the U.S. and the resulting death rates have almost tripled in the past 3 decades. New understanding of the relationships between the myocardium and LVF demonstrate a direct correlation between myocardial viability and improved patient survival. Because of this, myocardial viability is now a major investigative area in contemporary cardiology, one that holds significant clinical and prognostic relevance. Authored by physicians of international renown, the book brings together various disciplines affecting myocardial viability, with five main sections providing an introduction and comprehensive review of: basic concepts and mechanisms; vascular biology and cellular physiology; advances in functional imaging; and perfusion, metabolism and cell membrane integrity. New concepts, such as stunning and hibernation, are clarified, and subsequent novel diagnostic and therapeutic strategies are described. New and sophisticated examination techniques are also presented, as well as advances in instrumentation and imaging techniques, which may result in improved use of resources and enhanced efficiency of health care delivery. This monograph will serve as a reference source for those interested in the field of myocardial viability, and hopefully improve understanding between investigators from various disciplines. Clinical cardiologists, physicians, and nurses in the field, as well as radiologists, vascular surgeons, reperfusionists, cellular biologists and physiologists, and students will all find material of interest in this book.
