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
