Cardiac Ventriculography is a medical imaging test used to determine a patient's cardiac function in the right, or more typically, left ventricle. 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.
The 3 major measurements obtained by cardiac ventriculography are:
- Ejection Fraction
- Stroke Volume
- Cardiac Output
Radionuclide ventriculography
