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

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

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

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

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

Hi doctors, was just wondering what is a normal ejection fraction %age on a hida scan? What's good, what's bad?

Hi doctors, was just wondering what is a normal ejection fraction %age on a hida scan? What's good, what's bad?

Greater than 35%: Normal ejection fraction in adults usually is greater than 35%. Significance of ejection fractions has to be compared to clinical signs and symptoms of patient. ...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

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

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 ?g/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. -. ...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

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
