Magnetic resonance imaging is useful in diagnosing complications of myocardial infarction, such as pericarditis or pericardial effusion, valvular dysfunction, ventricular septal rupture, aneurysm, and intracardiac thrombus. Computed tomography is used to calculate the coronary artery calcium score. Echocardiography uses ultrasound reflected best at interfaces between tissues that have different densities. In the heart, these are the blood, cardiac valves, myocardium, and pericardium. Because all these structures differ in density, their borders can be seen on the echocardiogram. The standard 12-lead electrocardiogram provides a picture of electrical activity in the heart using 10 different electrode positions to create 12 unique views of electrical activity occurring within the heart.
