Angiography is a medical imaging technique that is used to visualize the lumen of blood vessels and organs of the body, particularly the veins, arteries and heart chambers. The procedure is done by injecting a radio-opaque contrast agent into the blood stream of a patient, followed by X-ray based imaging like fluoroscopy. Depending on the area under observation, angiography can be of various types such as coronary angiography, fluorescein angiography, peripheral angiography, microangiography and post mortem CT angiography. It is done to identify narrowing vessels, visualize arterial and venous supply to the brain, visualize blood vessels and blood in the coronary arteries. This book elucidates new techniques and applications of interventional radiology in a multidisciplinary manner. It strives to provide a fair idea about angiography and to help develop a better understanding of the latest advances within this field. This book is a vital tool for all researching or studying radiology as it gives incredible insights into emerging trends and concepts.
