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

Is hida scan a very common procedure?

HIDA scan is easy: Hida scan is a common test by nuclear medicine. Hida is injected into blood, then is taken up by your liver & excreted into the bile ducts. If your gallbladder functions (is not sick), it will "light up" when it concentrates the hida material. Giving cck then allows measurement of gallbladder emptying time, patency of the bile ducts, & how effectively the hida material enters your small bowel. ...Read more

Hida scan fluctuating numbers, what's wrong?

Up or down: It is really depend if the numbers are going down mean your gallbladder function getting the worst
if is up and down the test is not reliable
and depend on your symptoms
if the fluctuation up and down but still below 30% your gallbladder could be the problem. ...Read more

Still having pain after hida scan is this normal?

Pain at the: Injection site or abdominal pain? A standard HIDA scan should not induce abdominal pain. If you also received a CCK injection to check the gallbladder ejection fraction, however, it could cause temporary pain. ...Read more

Can you tell me what is expected during a hida scan?

Can you tell me what is expected during a hida scan?

HIDA: Hida scan involves IV injection of a tc tracer. The tracer doesn't cause any side effects. Physicians look to be sure that the gallbladder and bowel fill with tracer to rule out cystic duct (cholecystitis) or common bile duct obstruction. Hida is performed with or without cck. Cck is helpful for chronic conditions to determine a gallbladder ejection fraction. Cck may cause cramping or pain. ...Read more

Can you tell me the things can be seen by doing hida scan?

Can you tell me the things can be seen by doing hida scan?

Many things: Liver function, bile ducts, gall bladder, and bowel. Hida mimics bile excretion in body. Obstructions to duct of gall bladder, main bile duct, spasm of sphincter where bile duct enters duodenum. Cystic dilatations or outpouchings of common bile duct called choledochal cysts. In infants, lack of bile ducts or biliary atresia. Sometimes bowel obstruction or malrotation. Duodenogastric reflux/bile gastritis. ...Read more

Need a simple explaination for this. What happens when you get a hida scan?

Gall bladder test: The patient is injected intravenously with tc99m hida (radiotracer). The liver extracts the material from blood stream and excretes it into bile ducts, gall bladder, and bowel.(30-60 min imaging) usually when gall bladder is full, patient is injected IV with cck (hormone to contract gb)patient may experience some pain, and calculate % of gb emptying(60 min. Imaging) normal usually > 35% in adults. ...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 on 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?

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 an ejection fraction less than 30%, it is called dyskinesia and may be a cause for problems. ...Read more

What is HIDA scan for in context of diagnosing pancreatitis?

Gallstone etiology: In the dyerentiation of gallstone from non- gallstone pancreatitis, hida scanning can be helpful by identifying gall bladder duct obstruction associated with pancreatitis and is sometimes better than liver function profile and clinical picture. ...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 than 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 than perhaps whatever the test was ordered for is getting worse. Do you know what the results of the test were? ...Read more

I had a HIDA scan and report said gallbladder did not visualize. What is this?

Non visualized GB: If you have not eaten for a while, you can see non-visualization of the gallbladder during a HIDA scan. It basically means that this is an inconclusive test. ...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?

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
