Ct doppler3/26/2023 ![]() ![]() Extensive research has described the strengths and weaknesses of these conventional imaging modalities. In addition, nuclear medicine imaging is a well-established tool for the non-invasive assessment of myocardial perfusion in patients with suspected IHD. Cardiovascular computed tomography (CT) and magnetic resonance imaging (MRI) provide sophisticated and complementary information through an exceptional high-quality visualization of coronary arteries, as well as of the cardiac structures and function. Traditionally, stress echocardiography and invasive angiography have been valuable means for IHD diagnosis and treatment, respectively. The assessment of myocardial ischemic changes is crucial to diagnose IHD accurately, to estimate patients’ prognosis, and therefore to evaluate optimal therapeutic options. Ischemic heart disease (IHD) is the leading cause of death globally. In addition, we discuss new opportunities brought by artificial intelligence, while addressing promising future scenarios and the challenges for the application of artificial intelligence in the field of cardiac imaging. ![]() In this review article, we provide an overview of the emerging methods for the non-invasive characterization of ischemic heart disease, including coronary ultrafast Doppler angiography, photon-counting computed tomography (CT), micro-CT (for preclinical studies), low-field and ultrahigh-field MRI, and 11C-methionine positron emission tomography. These new methods may bring advances in the understanding of ischemic heart disease with potential major changes in the current clinical practice. While these structural changes have been described by conventional imaging modalities mostly on a macroscopic scale- i.e., late gadolinium enhancement at magnetic resonance imaging (MRI)-in recent years, novel imaging methods have shown the potential to unveil an even more detailed picture of the postischemic myocardial phenomena. After an ischemic event, disruptive changes in the healthy myocardium may gradually develop and may ultimately turn into fibrotic scar. ![]()
