What Type Of Machine Is Used In A Hida Scan
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
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
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
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
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
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
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
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
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
None: Both tests the same: gallbladder function, but use different trace material. ...Read more
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
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
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
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
Not necessarily: A diagnosis requires assessment of both the images, and the symptoms. It is possible to have no pain and still have a diseased gallbladder. ...Read more
Non visualized GB: If you have not eaten for awhile, you can see non-visualization of the gallbladder during a HIDA scan. It basically means that this is an inconclusive test. ...Read more
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
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
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
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
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
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
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
Gall bladder test: Nothing by mouth for 6 hrs. Patient injected intravenously with tc99m hida (radiotracer).Patient lies on table with scaning camera over anterior abdomen. First part of study extraction of tracer from blood stream, visualization of gb and bowel (30-40 min)slow IV injection of cholecystokinin, stimulates gall bladder contraction. (60 min more imaging).Sometimes discomfort possibly related to gb disease. ...Read more
Norman HIDA scan results but pain during CCK injection made my already pain ten times worse what does this mean?
Hida scan came back 62% was only 37% 10 yrs ago so what else could be causing all my attacks if the gallbladder is functioning?
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?
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
I recently had a hida scan. The night of the examination, I accidentally urinated on myself. Is this dangerous? Any effects of radioactive exposure?
Did you wash it?: If you washed the parts that you urinated on, promptly, there is little risk of any radiation exposure or damage. ...Read more
