Cardiovascular magnetic resonance imaging (CMRI) is the medical diagnostic imaging technology used for the non-invasive assessment of the structure and function of the cardiovascular system. Standard MRI sequences are customized for cardiac imaging with the utilization of high temporal resolution protocols and ECG gating. CMRI is a complementary technique to other techniques, such as cardiac CT, echocardiography and nuclear medicine. A common major birth defect is congenital heart defect. CMRI provides the essential insight into the nature of the defect without the use of harmful X-rays. This book unfolds the innovative aspects of cardiovascular magnetic resonance imaging, which will be crucial for the progress of this field in the future. It includes some of the vital pieces of work being conducted across the world, on various topics related to this field. As this field is emerging at a rapid pace, the contents of this book will help the readers understand the modern techniques and applications of the subject.
