Cardiac imaging refers to the use of non-invasive imaging techniques for capturing images of the heart and surrounding structures. These techniques comprise ultrasound, magnetic resonance imaging (MRI), computed tomography (CT), and nuclear medicine (NM) imaging with PET or SPECT. When these techniques are used exclusively for imaging of heart, they are known as echocardiography, cardiac MRI, cardiac CT, cardiac PET, and cardiac SPECT, respectively. Cardiac imaging is usually prescribed for screening and diagnosing heart conditions, determining the occurrence of a heart attack and its extent, determining the cause of symptoms such as chest pain and shortness of breath, and determining the status of cardiovascular diseases. This book presents a comprehensive overview of the major imaging methods used for diagnosing cardiovascular diseases. It is a compilation of chapters that discuss the most vital concepts and emerging trends in this field. The book will prove to be immensely beneficial to students and researchers in the field of cardiology and cardiac imaging.
