Ultrasonic imaging is the first-line method for imaging the structure of the heart. Cardiovascular computed tomography is rapidly complementing ultrasonic imaging and replacing invasive methods of examination in many problem settings. CMR is important in the monitoring of congenital heart defects and diagnosis of severe inflammatory cardiomyopathies. CMR is beneficial especially in the imaging of regurgitant valvular disease, assessment of ventricular volume and contractility and in cases of limited visibility on ultrasonic imaging. ECG-synchronized computed tomography is well suited as a preoperative examination for young patients undergoing aorthic or valve surgery.
