Cardiac ventriculography
Cardiac ventriculography is a medical imaging test used to determine a person's heart function in the right, or left ventricle.[1] Cardiac ventriculography involves injecting contrast media into the heart's ventricle(s) to measure the volume of blood pumped. Cardiac ventriculography can be performed with a radionuclide in radionuclide ventriculography or with an iodine-based contrast in cardiac chamber catheterization.

Purpose | test cardiac function in the right, or left ventricle. |
The 3 major measurements obtained by cardiac ventriculography are:
These three measurements share a commonality of ratios between end systolic volume and end diastolic volume and all lend mathematical structure to the common medical term systole.
Radionuclide ventriculography
Radionuclide ventriculography is a form of nuclear imaging, where a gamma camera is used to create an image following injection of radioactive material, usually Technetium-99m (99mTc).
