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 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

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

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

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 should I expect during a hida scan?

HIDA scan: You'll change into a gown and will lay on the nuclear medicine scanner bed. A medication (radioactive tracer) is then injected into a vein in your arm (you may feel some pressure). The gamma camera passes back and forth over your belly and takes pictures for about an hour. Sometimes, more pictures may be needed. In most cases you can go about your day after your hida scan. ...Read more

How can you specifically alter hida scan results?

False positives: Variability in results depends on method of test, interpretative skills,patient symptoms. It is not perfect.If gb ejection fraction is low in patient with biliary colic , chronic gall bladder disease /biliary dyskinesia probable. With acute symptoms non visualization of gb means acute cholecystitis, surgical emergency.False positives prolonged fasting, tpn,alcoholism, recent narcotic, pancreatitis ...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

I had a hida scan today, and the second part caused me pain. Why?

Mimics gb symptoms: Patient is injected intravenously with isotope that selectively is extracted 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. Some patients do get nausea and pain and decreased gb contraction consistent with gb disease. ...Read more
