Cardiovascular imaging is undertaken to investigate a heart condition. Various techniques are used for cardiac imaging such as coronary catheterization, intravascular ultrasound, echocardiogram, cardiac CT scan, cardiac PET scan, cardiac MRI, etc. Coronary catheterization requires blood sampling and monitoring of blood pressure by inserting a catheter into the heart to determine heart function. Intravascular ultrasound is an imaging technique that uses a long, thin, specially designed catheter that is attached to ultrasound equipment to visualize the interior wall of blood vessels and visualize the lumen. An echocardiogram is done by using ultrasonic waves for the visualization of the heart chamber and blood flow. This book explores all the important aspects of cardiovascular imaging in the present day scenario. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field. Scientists and students actively engaged in cardiovascular imaging will find this book full of crucial and unexplored concepts.
