Hida Scan (Definition)

Patient is injected intravenously with isotope tagged to chemical hida that is extracted preferentially by liver cells mimicking bile. Some of this is stored in gall bladder and some enters small bowel from common bile duct. Cholecystokinin is a natural hormone slowly injected intravenously to stimulate gall bladder contraction. Normal function has at least 50% ...Read more

During a hida scan, what is a normal gallbladder ejection fraction?

During a hida scan, what is a normal gallbladder ejection fraction?

>35 %: A normal gallbladder ejection fraction is usually over 35%. Anything less than this would be considered dysfunction of the gallbladder or biliary dyskinesia. ...Read more

Hi doctors, was just wondering what is considered a high gallbladder ejection fraction during a hida scan?

Hi doctors, was just wondering what is considered a high gallbladder ejection fraction during a hida scan?

Usually normal: Hyperkinetic or hyperactive gallbladder is not generally accepted as a diagnosis. A small group of patients (63) was symptomatic with cck infusion with greater than 80% ejection fraction. 28 of these patients underwent removal of gall bladder. 97% of these 28 patients showed improvement in symptoms following surgery. . More published retrospective and prospective studies needed. ...Read more

Doctor ordered a HIDA scan without ejection fraction. What's the point if I won't see gallbladder ejection fraction?

Doctor ordered a HIDA scan without ejection fraction. What's the point if I won't see gallbladder ejection fraction?

Rule out Acute Chole: The doctor ordered it to make sure your cystic duct is open and you do not have an Acute Cholecystitis, a common bile duct or small bowel obstruction. You stated that you have Gilbert's disease. Thus the doctor may also want to see if you have acute hepatocellular disease. The Ejection fraction will tell him if you do or do not have chronic cholecystitis. ...Read more

What does early homogeneous uptake of isotope within liver on a hida scan.. Is this ok? Also saod depressed gallbladder ejection fraction 10%

What does early homogeneous uptake of isotope within liver on a hida scan.. Is this ok? Also saod depressed gallbladder ejection fraction 10%

Normal: A hida scan is a gallbladder function test. The first medication is able to be followed as it goes through. The first thing seen is uptake by the liver. The liver takes the isotope out of the blood and dumps it in the bile. Once we see it in the gallbladder and bowel a 2nd med is given to tell the gb to work. The 10% is a decreased function of your gall bladder. Should be 50% +. See surgeon. ...Read more

What does ejection fraction means? I'm having a hida scan tomorrow because i'v been diagnosed w/a gallbladder sludge

What does ejection fraction means? I'm having a hida scan tomorrow because i'v been diagnosed w/a gallbladder sludge

Sludge: Gall bladder sludge is seen on ultrasound exam. The nuclear medicine nuclear scan relates how well gall bladder is functioning by how well gb contracts. Sludge in gall bladder can have either normal or abnormal study.The scan also demonstrate relative function of liver and abnormalities in common bile duct. In adults most clinicians use above 35% as normal gb ejectin value. ...Read more

Will a hida scan show if gallbladder is acute vs chronic. My ejection fraction 7% . Pain even when not eating .Some nausea. Vomited x1?

Will a hida scan show if gallbladder is acute vs chronic. My ejection fraction 7% . Pain even when not eating .Some nausea. Vomited x1?

It does : In acute chokecystitis, the hida scan will typically show obstruction of the cystic duct (the duct to the gallbladder) this results in a nonviualized gallbladder. In chronic cholecystitis the gallbladder can be seen, meaning the duct is open. A stimulant is then given and the ability of the gallbladder to empty is measured. 50-75% ejection is normal. Less than 25% is considered dysfunctional. ...Read more

Is the ejection fraction painful during hida? I have a gallbladder sludge, and a nuclear med scan tomorrow.

Is the ejection fraction painful during hida? I have a gallbladder sludge, and a nuclear med scan tomorrow.

CCK: To determine a gallbladder ejection fraction, a medication called cck is administered iv. Your body normally has its own cck which makes the gallbladder contract. The exogenous cck may simulate any symptoms which you feel when you normally eat a fatty meal. If you get cramping, nausea, etc.....You may experience this with cck. Symptoms are often more pronounced with rapid speed of injection. ...Read more

Hida scan results ejection fraction rates 30% at 30minutes 46% at 45 minutes and 50% at 60 minutes. I am very symptomatic with eating, recorecommendat?

Depends on how the : Gallbladder ejection fraction was performed. If the gallbladder contraction drug (cck or sincalide) was administered at a dose of 0.02 micrograms/kilogram over 1 hour, then a normal gallbladder ejection fraction would be greater than or equal to 38% at one hour. Unfortunately, there is variability in the % depending on exactly how it is performed. Check with your doctor for what normal is. ...Read more
