Can A Hida Scan Be Wrong
Up or down:
It is really depend if the numbers are going down mean your gallbladder function getting 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
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
Results were normal from an ultrasound and hida scan, what else can I do to figure out what's wrong?
other G.I problems: If the ultrasound and hida scan are completely normal, it is very likely that you do not have any biliary tree problems. However, many other diseases may mimic some hepatobiliary diseases such as ulcers or inflammation of the oesophagus, stomach or duodenum. Blood tests may also be useful to rule out the presence of h.Pilori which may cause similar symptoms. ...Read more
Could a Hida scan and Ct scan miss something wrong with the gallbladder? Upper right quadrant pain. Normal lab values for liver kidneys and pancreas?
While no test is perfect; a normal HIDA essentially shows that the gallbladder is functioning well. There are " quantitative" HIDA scans that are more sensitive than a regular scan.
It is more likely that your pain is not from the gallbladder (often difficult to exactly pin down, but you are unlikely to get improvement having the gallbladder removed. ...Read more
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
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
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
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
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
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
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
