Cardiac imaging is a subspecialty of diagnostic radiology. A cardiovascular radiologist directs or performs and then deciphers clinical pictures to analyze illnesses of the heart like coronary illness, leaking heart valves, aneurysms, and deformities in the size and state of the heart. A cardiac radiologist utilizes imaging procedures, for example, X-rays, ultrasound (echocardiograms), computer tomography, and MRI (magnetic resonance imaging) for these diagnoses. These tests are utilized to evaluate for coronary illness, figure out the underlying cause got the indications and screen the heart, and confirm the success of the treatment process. There have been plenty of discoveries and research prospects in this field of medicine with the discovery of nuclear cardiac imaging, 16 section computer tomography imaging, and in the development of techniques and methodologies to improve the imaging systems also study the side effects for the tissues concerning the amount of radiation from these systems. 
The course is designed to provide ample knowledge and extensive training for aspirants to be able to understand indications, select the appropriate diagnostic tool, come to accurate diagnosis and then direct the patient to appropriate treatment methods and management techniques. The course initially provides the student with ample training in basic medical sciences such as anatomy, where the student learns about the embryology of heart and blood vessels, the basic anatomy of the heart, vessels around and peripheral and visceral arteries, the blood supply of the heart and anatomy of the vascular system mainly related to the aorta and brachiocephalic vessels. It then studies other basic sciences such as physiology where basic and applied cardiovascular physiology and basics of hemodynamics in acquired and congenital cardiac conditions are studies and then the students are taught about pathology and microbiology systems, and then microbiology and biochemistry and biomedical engineering. The course then studies the imaging techniques for the cardiothoracic system where they are first taught about the imaging equipment and then symptoms, occurrences, and signs of heart disease such as heart failure (acute and chronic heart failure), systemic hypertension, primary and secondary cardiac arrhythmias, sudden cardiac death (syncope), heart muscle disease (myocarditis and cardiomyopathy) pericardial disease (acute and chronic pericarditis), constrictive pericarditis, pericardial effusion, Infective endocarditis, etc. 
A Doctor of Medicine - Cardiac Radiology degree is a certification that aims to provide an aspirant with a license to practice, diagnose and offer treatment procedures and directions to patients with anomalies in any issue related to the heart and the heart wall. The major imaging techniques include CT - Coronary Angiography (CTCA), Coronary Artery Calcium Scoring, and MRI Heart (Cardiac MRI). The major job opportunities and scope for a person having secured the degree would include, working as a physician in major hospitals, and healthcare centers in the private and government sector. They can also work as radiologists and in diagnostic centers, there are also job opportunities to be followed in the departments for diagnostic medicine. Where patients with ailments that do not follow regular symptoms are diagnosed using advanced scanning techniques. There is also scope to be working in the fields of research where various new imaging systems are being studied to be able to reduce radiation exposure and help understand the system with improved accuracy.
