Is a hida scan painful?

Is a hida scan painful?

Sometimes: Hida scans are usually ordered for 2 reasons: to see if the gallbladder is obstructed, or (when combined with cck) to check gallbladder function. Hida is painless but the cck injection may reproduce a gallbladder attack. This information is very useful since, if your pain is reproduced, it suggests that your pain is arising from the gallbladder. ...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

What is observed during a hida scan?

What is observed during a hida scan?

One/ two phase exam: Hida scan is usually two part examination. First phase intravenous injection of isotope with technetium accumulating in liver, excreted like bile into bile ducts, accumulating in gall bladder, and excreted into bowel.Second phase slow intravenous injection of cck, hormone, causing gb contraction determing gb ejection fraction. Sometimes discomfort mimicing abdominal symptoms. Looking for gb disease, ...Read more

What does 8 % on Hida scan mean?

Ejection fraction: The ejection fraction is the portion of the gallbladder contents that are expressed from the gallbladder with contraction. Normally the gallbladder has an ejection fraction greater than 35%. An EF of 8% may indicate abnormal gallbladder function, and it needs to be considered along with the clinical situation to determine if a cholecystectomy should be performed. Good luck. ...Read more

What is the definition or description of: hida scan?

Hepatobiliary study: 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% emptying of gall bladder. ...Read more

What exactly is a hida scan and what does it involve?

Gall bladder scan: A hida scan may be used to evaluate for acute or chronic cholecystitis or gall bladder dysfunction/dyskinesia. The patient does not have to do much but stay still. It helps show whether your liver, gallbladder or sphincter are malfunctioning. ...Read more

I got a Hida scan and it showed 41%. Is this normal or should it be concerning?

No: It sounds like you had a CCK test with the Hida scan which is used to determine gallbladder function. The cutoff for the "ejection fraction" or the ability of the gallbladder to contract is considered to be 35%. Thus your ejection fraction, while on the low side, would still be within the range of normal. ...Read more

Hida scan safe if you have pancreatitis?

Yes: Hida scan is a method to look at the ability of the liver to excrete a radioactive dye - a nuclear medicine study. It may tell if there is blockage of bile coming out of the liver or if the gallbladder is not working. Since it does not involve instrumentation of the pancreas, it does not worsen pancreatitis. It does have limitations, cannot be used if the bilirubin is elevated and not specific. ...Read more

15% hida scan should I have gallbladder out?

15% hida scan should I have gallbladder out?

Depends: Depends if symptoms related to biliary colic. Other alternatives are diet avoiding fatty foods that can cause gall bladder attacks. 15% is low ejection fraction for gall bladder and usually means chronic gall bladder disease or dyskinesia. Should consult your physician for educated decision. ...Read more

Will being hungover change results of hida scan?

Will being hungover change results of hida scan?

Why be hungover: Alcoholism may increase bile viscosity and result in abnormal hepatobiliary function. Should have HIDA test performed under optimal conditions. ...Read more

Are there ways to get a false positive hida scan?

Yes: If you are fasting for more than 12 hours prior to scan, the gallbladder is full of bile, therefore the nuclear radiotracer cannot get inside the gallbladder. This will give the appearance of acute inflammation or cholecystitis. ...Read more

Does 45% hida scan mean my gallbladder is getting sick?

No.: There are typically 2 ways to use the results of a hida scan. If the gallbladder doesn't appear, then that is consistent with disease (called cholecystitis). If the functioning of the gallbladder is poor with a ejection fraction less than 30%, it is called dyskinesia and may be a cause for problems. ...Read more

Hida scan resultsare 34% with no stones. What is my prognosis?

Ejection fraction: The 34% is the ejection fraction, the effectiveness of gallbladder contraction which is at around the lower end of normal. Talk to your doctor as I am sure this was done due to symptoms, and that is what your doctor is treating and may not necessarily be the numbers. ...Read more

Hi doctors, was just wondering what to expect during a hida scan?

Gall bladder test: The patient is injected intravenously with tc99m hida (radiotracer).The patient lies on table with scaning camera over anterior abdomen. First part of study shows extracction of tracer from blood stream, visualization of gb and bowel. (30-40 min) patient receives slow injection of cck to stimulate gall bladder contraction. (60 min more imaging).Sometimes discomfort possibly related to gb disease. ...Read more

Before hida scan I fasted for 20 hrs could this throw the results off?

Not likely: Usually we say don't fast more than 24 hrs. So in general 20 hrs would probably be ok...We would not want someone to fast much longer then that. However, if someone has fasted longer than 24 hrs, a medicine can be given before the study...So that we don't have problems caused by this. ...Read more

My hida scan said my gallbladder is working at 29%. What does that mean?

Borderline: That means that after they stimulated your gallbladder, it ejected 29% of the radioactive tracer. Typically if it is less than 30-35% (depending on the lab), it indicates some type of gallbladder dysfunction as the etiology of a person's pain that may be helped by surgical intervention. However, since you are on the borderline, your physician will make a decision based on your clinical condition. ...Read more

Can hida scan irritate the gallbladder? Since I had mine my pain is worse?

Not usually.: The hida scan is a nuclear medicine test that measures the uptake of some radiolabeled IV medicine. It is not commonly associated with causing pain. If your pain is worse then perhaps whatever the test was ordered for is getting worse. Do you know what the results of the test were? ...Read more

Is it true that fasting fkr 24 hours prior to HIDA scan can cause false positive?

Yes: Yes...false positive can occur with prolonged fasting. If you fast for >24 hours then the gallbladder may already be filled and fail to fill with the radiotracer. ...Read more

I took first part of hida scan and they would not continue it. What could reason be?

Depends.: If non visualization of gall bladder can not do ejection fraction. Non visualization may mean cystic duct obstruction or in some circumstances acute cholecystits. If evidence of significant biliary obstruction many clinicians will not administer CCK to produce gb contraction. You should consult physician ordering or performing test. ...Read more

I'm having to get a hida scan. Can someone walk me thru it so I know what to expect?

I'm having to get a hida scan. Can someone walk me thru it so I know what to expect?

Nuclear Imaging: You will get an IV and injected with small dose of radiotracer that is specific for the liver. You will lay on a table for about an hour while images are obtained. Then, you may get an injection of a hormone that causes the gallbladder to contract (cholecystokinin) and a few more images will be obtained. The test will assess gallbladder function and whether your gallbladder is inflamed. ...Read more

I'm still hurting had a hida scan done gallbladder is at 53% could I still need it out?

RUQ pain: Yes you may very well still need a Gall Bladder removal. If your HIDA was done with CCK (Cholestokinin) it could help in that decision if your pain is reproduced. If CCK is negative you may need a CT scan of your Abdomen. I would recommend a consult with liver function test results as well ...Read more

My gallbladder was still highlighted at the end of my hida scan. What does this indicate?

Probably nothing: Over the course of a routine hida scan, the gallbladder accumulates the radiotracer, so it is actually normal to see the gallbladder at the end of the scan. Even if you were given cck to cause the gallbladder to contract (this is how the ejection fraction is calculated) the gallbladder usually does not empty completely and will still be visible but probably a bit smaller. ...Read more

How do I prep for a hida scan? And could pain pills affect the scan even. If its 5 days away

How do I prep for a hida scan? And could pain pills affect the scan even. If its 5 days away

Patient Preparation: You can't eat or drink anything at least 4-6 hours before the scan, but not more than 24 hour so it's best to schedule your test early in the morning. Keep your doctor informed about any medications you are taking. Usually, all opiate type pain medications (morphine, codeine, etc) have to be stopped 6 hours before the test. You may take your other medications with a sip of water. ...Read more

If you have a reaction to the hida scan medicattion does that mean your gallbladder is bad?

If you have a reaction to the hida scan medicattion does that mean your gallbladder is bad?

Not necessarily: There are different types of "reaction".
Although very rare, it is possible to have an allergic reaction to one of the medicines used during the study. This reaction would have nothing to do with the gallbladder.
If a medication is given in attempt to cause your gallbladder to squeeze down...And it is given to fast. It can cause spasm/pain... (as a normal reaction). So. No. ...Read more

Us and. Hida scan all normal, except did show sludge, but I still have all the symptoms and the pain, now what? Getting frustrated

Probably not gb: Sludge or gravel in gall bladder does not usually cause symptoms and can disappear with time. Endoscopy, blood tests, and other imaging testing can examine stomach, large bowel and small bowel for possible contribution to your symptoms. Abdominal symptoms can be related to stomach, pancreas, liver etc. Another option is to follow gall bladder diet with elimination of certain foods to see if helps. ...Read more

17 y/o gallbladder not shwoing up on hida scan after 2 hours. Going back in another 2 hrs to see if shows up. Why would it take so long to show?

17 y/o gallbladder not shwoing up on hida scan after 2 hours. Going back in another 2 hrs to see if shows up. Why would it take so long to show?

HIDA...: If tracer is visualized in the bowel at 1 hour of imaging but gallbladder is not visualized, there are two options. First is to give morphine which causes contraction of sphincter of oddi ; speeds up study so that imaging is only performed for an additional 30 min. Alternatively, the old-school method is to image up to 4 hours. If gallbladder is not seen at 4 hours --> cystic duct obstruction. ...Read more
