WebYour HIDA scan measured the "ejection fraction" of your gallbladder. Once the gallbladder is filled with HIDA (a radioactive substance), the hormone cholecystokinin is injected into a vein. The cholecystokinin stimulates the gallbladder into emptying out the HIDA. Healthy gallbladders squeeze out at least 35% of the HIDA. WebStroke volume can be obtained by: 1) SV = EDV – ESV (when end systolic volume is known) 2) Cardiac output in mL/min / Heart rate in bpm. Example calculation from the ejection fraction calculator: for a normal range stroke volume of 70 mL and a left ventricular EDV value of 120 mL, the ejection fraction is: 70/120 = 0.58, meaning in … WebEjection fraction measures the amount of blood the left ventricle of the heart pumps out to your body with each heartbeat.
