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 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== (詳細はnuclear imaging, where a gamma camera is used to create an image following injection of radioactive material, usually Technetium-99m (99mTc). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「cardiac ventriculography」の詳細全文を読む スポンサード リンク
