1. X-ray imaging of the heart and great vessels made visible by injection of a radiopaque solution.
2. Angiography of the heart and great vessels; contrast material may be injected into a blood vessel or one of the cardiac chambers.

Images obtained can be analyzed to determine parameters of ventricular function, including ventricular ejection fractions, cardiac output, ejection rates, stroke volume, end-diastolic volume, and end-systolic volume, as well as to test the effects of exercise.

Radiography of vessels or of the heart, with recordings of the images on motion-picture film; therefore, permitting the study of motion.

It is especially useful in the study of coronary arteries and the chambers of the heart.

The diagnostic value of conventional determination of cerebral circulation time from serial angiograms is questioned and compared with the results of angiocinematographic investigation.

A diagnostic procedure that uses high-frequency sound waves to image arteries and veins.

Sometimes referred to as "color flow Doppler" because the arteries will appear as red on the screen and the veins will be blue. Useful in the determination of vascular obstruction.

A radiograph of blood vessels taken during angiography
1. Radiography of vessels after the injection of a radiopaque contrast material; usually requires percutaneous insertion of a radiopaque catheter and positioning under fluoroscopic control.
2. A special kind of sphygmograph or instrument for recording on paper the movements of the pulse.
1. Determination of the arrangement of blood or lymph vessels without dissection, by capillaroscopy, fluoroscopy, or radiography.
2. The radiographic visualization of blood vessels following introduction of contrast material; used as a diagnostic aid in such conditions as stroke syndrome and myocardial infarction.
