- angiography
- x-ray imaging of blood vessels after injection of contrast material
- arteriography
- x-ray imaging of of arteries after injection of contrast into the aorta or artery
- digital subtraction angiography (DSA)
- video equipment and a computer produces x-ray images of blood vessels
- doppler ultrasound
- sound waves measure movement of blood flow
- echocardiography (ECHO)
- high-frequency sound waves and echoes produce images of the heart
- positron emission tomography (PET) scan
- images showing blood flow and function of the myocardium following uptake of radioactive substances
- technetium (Tc) 99m Sestamibi scan
-
injected IV and taken up in the area of an MI
Also used with an exercise tolerance test (ETT-MIBI) - thallium 201 scan
- concentration of a radioactive substance is measured in the myocardium
- cardiac MRI
- images of cardiac tissue are produced with magnetic waves
- cardiac catheterization
- a thin, flexible tube is guided into the heart via a vein or an artery
- electrocardiography (ECG) (EKG)
- recording of electricity flowing through the heart
- Holter monitoring
- an ECG device is worn during a 24-hour period to detect cardiac arryhthmias
- stress test
- exercise tolerance test (ETT) determines the heart's response to physical exertion (stress)
