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

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

I had a hida scan done result ejection fraction of 35% I am diabetic pain is worse since test and blood sugars are high is this normal?

I had a hida scan done result ejection fraction of 35%  I am diabetic pain is worse since test and blood sugars are high is this normal?

Borderline result: 35% gb ejection fraction in most labs is borderline normal. Your physician has to consider gb ejection fraction along with symptoms of biliary colic for proper therapy.Ingestion of food prior to study does affect result. Being diabetic I do not know how many hours fasting prior to test. Usually 6-8 hours. ...Read more

What am I looking at in terms of treatment?

Depends: If you are having symptoms of gallbladder disease, like upper abdominal pain or nausea, you will likely benefit from gallbladder removal. If you are not having those symptoms, you may be able to avoid operation--for now. ...Read more

I have recently developed urq pain. Normal ultrasound, lab work and hida scan. Ejection fraction 98%. Pain worse after meals. Tender to touch. Nausea.

See a surgeon : Cholescintigraphy for acute cholecystitis has sensitivity of 97%, specificity of 94%.[2] several investigators have found the sensitivity being consistently higher than 90% though specificity has varied from 73%- 99%, yet compared to ultrasonography, cholescintigraphy has proven to be superior. As you can see, at least 3% of the time the hida scan is wrong. You may need to find a surgeon who is willing to go in and take a look on the basis of an abnormal physical examination without undue reliance on testing. I woulddefinitely recommend a second opinion.Best wishes. The information above is from wikipedia. ...Read more

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

Ejection fraction is: A measure of how effectively the gallbladder releases bile when it contracts. During a hida scan, the gallbladder accumulates the radioactive substance. Another medication is then given (cck) which stimulates the gallbladder to contract. A special camera measures how well the gallbladder empties. This is reported as a percentage. If abnormal, this may be a source of pain without gallstones. ...Read more

Is there any study that shows using Half & Half in a HIDA scan is as accurate as CCK? My ejection fraction was 31%

Is there any study that shows using Half & Half in a HIDA scan is as accurate as CCK?   My ejection fraction was 31%

Yes.: Here is the link for that study:

http://jnm.snmjournals.org/content/43/12/1603.full

It shows that there is wide variability in the ejection fraction measured when half and half, instead of CCK, is used in a HIDA scan. However, the study concludes that both methods are acceptable. Hope that helps! ...Read more

Why did they stop the HIDA scan (without CCK) before testing the ejection fraction? Can't that be a problem of its own?

Yes: Did they have CCk? It is not generally available. Have to substitute standardized fatty meal. Otherwise results are equivocal. Sometimes clinicians will not use CCK if suspect acute obstruction of biliary system or if no activity is in gall bladder. Should ask institiution performing the test for explanation. CCK or fatty meal substitute gives indication of gall bladder function. ...Read more

What is likelyhood of GB removal with 0% ejection fraction after 30 mins. and 10% after 60 mins from HIDA scan? Are there any alternatives to removal?

What is likelyhood of GB removal with 0% ejection fraction after 30 mins. and 10% after 60 mins from HIDA scan? Are there any alternatives to removal?

Avoiding fatty food: Gall bladder ejection fraction of 0% is the lowest you can have.Normal ef is above 35%. The gall bladder is usually best removed for relief of symptoms. Avoiding fatty foods and watching diet may help symptoms for limited amount of time.If chronic gb disease suffer chronic pain. Acute chiolecystiitis iusually associataed with gall stones often is surgiical emergency. ...Read more

If the body doesn't produce cholecystokinin (for some reason), wouldn't the ejection fraction part of a hida scan produce a false negative?

If the body doesn't produce cholecystokinin (for some reason), wouldn't the ejection fraction part of a hida scan produce a false negative?

CCK is injected: For a hida scan the cck is given by IV injection: sincalide (cck) pretreatment is a c-terminal octapeptide of cholecystokinin (cck), in doses of 0.01–0.02 μg/kg, may be given intravenously, 30–60 min prior to the hepatobiliary tracer injection to minimize the
potential for a false-positive study (reference: http://interactive.Snm.Org/docs/pg_ch11_0703.Pdf ) see guideline for more information.

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

Your hida scan is abnormal, with a low ejection fraction and reproduction of symptoms with the cck injection. What does this mean in layman's terms?

Gallbladder not work: That mean your gallbladder is not working as good as it suppose to be
if you have symptoms of gallbladder colic consider medical treatment first if it did not work based on your symptoms make sure you do not have other upper digestive problems like ulcer or reflux or irritable bowel syndrome
your last solution should be surgery do not jump to surgery too fast your doctor will advise you. ...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

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

Can biliary dyskinesia GB recover to normal after stopping meds that cause low ejection fraction? How long would it take to recover b4 new HIDA scan?

Not likely: You almost certainly have mechanical obstruction of the GB, even though this may be only due to thickened bile, sludge, or gravel, and may be intermittent. Medications or supplements have virtually no influence on this process. Low fat diet can lessen the severity of symptoms by lessening GB contractions.

See your doctor. ...Read more

Gallbladder ultra sound was normal w/NO stones... HIDA scan showed ejection fraction at 10%. I have frequent attacks, what are my chances of Gangrene?

Not common : Unless you have severe pain and fever, gangrene is unlikely. Avoid fatty and greasy foods. Gallbladder contracts when stimulated by fatty foods and this is when pain occurs (after fatty or greasy meals). ejection fraction is normally over 30 %. ...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

Having mid-back pain to right of spine for hours after eating.  Hida scan and gb ultrasound=normal. Ejection fraction=91%.  Any ideas about the cause?

Possibly not gb: Most symptoms related to gall bladder occur in right upper quadrant of the abdomen. Your symptoms sound like other portions of the gastrointestinal tract may be involved, endoscopy, blood tests, and other imaging testing will examine large bowel and small bowel for possible contribution to your symptoms. ...Read more

Got hida scan of gallbladder, ejection was 94% which is good. But am bein sent to Genral surgeon and dont know why. Why would this happen?

Symptoms ? : Do you have classic GB symptoms ?? That might be the reason. (I assume you had an US done that showed no gallstones?) HIDAs are good for showing obstructions of the gallbladder outlet but not so good at picking up random stone pain. Did you have pain when they gave you the CCK ?? If your studies are all normal and you had no pain with the HIDA I would look for another cause of your pain ...Read more

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
