Nuclear Test For Gallbladder
I have a gallbladder sludge and tomorrow have to have a nuclear med test for gallbladder. Will sludge show up on test? Will results show normal ?
No.: "sludge" is seen on ultrasound. The test you are having, a hida scan, watches the gall bladder empty. It's not as accurate as ultrasound for seeing fine details like sludge, but it sees if you have pain during the test, and the "ejection fraction" is low, it is abnormal, and usually surgery is recommended. ...Read moreSee 2 more doctor answers
From a cardiac perspective nuclear scans are performed with either exercise or medications to examine the blood flow in the heart. Before and at peak exercise the patient is given a radio tracer which travels in the blood to the heart. Pictures are take before and after exercise and compared to evaluate for any blockages in the ...Read more
Hida can be abnormal: Hida test requires patient fasting for about 6 hrs before test and o pain medications, affecting gb emptying.Injected IV with isotopetc99m hida. Patient supine with camera above abdomen imaging for at least 30 min. Usually additional imaging in different projections up to 45 min - 60 min.If gall bladder well seen, injected with slow infusion of cck. Gb emptying evaluated. Sometimes nausea/pain. ...Read more
HIDA scan with EF: After initial feeling with a radiotracer, your gallbladder contraction was stimulated and the percentage of radiolabeled bile ejected from the gallbladder was measured as "ejection fraction" or ef.This is a measure of gallbladder contractility and thus funcnution. Generally efs are greater than 50%, and < than 35% is considered abnormal. Yours is on the limit and clinical correlation is important. ...Read moreSee 4 more doctor answers
Yes for acute: The accuracy of cholescintigraphy (nuclear scan) for diagnosis of acute calculous cholecystitis has been greater than 95%, and the accuracy for acute acalculous cholecystitis is only slightly less. A normal scan with gallbladder visualization almost always excludes a diagnosis of acute cholecystitis. ...Read moreSee 1 more doctor answer
Had a nuclear heart stress test. Right after, dr. Did my hida scan on the gallbladder. Did not give more nuclear stuff. Will this affect hida results?
Unusual but okay: Nuclear cardiac stress test is a nuclear imaging method that shows how well blood flows into the heart muscle, both at rest and during activity. This uses a radiopharmaceutical, such as thallium or sestamibi. However, tc-99m sestamibi, has relatively high liver uptake and studies have utilized this for assessment of gallbladder contraction also. (j gastrointestin liver dis, 2007; 16:157). ...Read moreSee 1 more doctor answer
No caffeine 24 hrs: Among other things to withhold, caffeine is probably the most important as it negates the effect of adenosine, preventing any stress. Other common things are don't eat for at least 4 hours prior to the test, no chocolate, stop some medications. Call the testing office for their specific protocol. ...Read more
Safe: In pediatric nuclear medicine the radiation dose is calculated per weight of child.Children receive lower doses than adults. Technetium is short iived isotope with 6 hr half life. If child is having anemia or blood in stools test is worth while in trying to define source of bleeding. ...Read moreSee 2 more doctor answers
Depends why elevated: This depends on why you have an elevated ANA. It can be there for lots of reasons. Classically we use this to diagnose systemic lupus erythematosus but most people with a positive ANA do not have systemic lupus erythematosus. As a rheumatologist we are asked to see a lot of people with a positive ANA Most of the time we find some other cause. Yours is high but it may not be high for any bad reason ...Read more
Varies: Different locations in the us charge different amounts for this study, for instance east vs. West coast. Differences in price can occur in same city, private office vs. Hospital. Also having medical insurance obviously reduces cost to patient. Most offices charge reduced rate for paying cash for the study. You can find places recommended by your doctor and price different offices/labs. ...Read moreSee 2 more doctor answers
Low iodine diet: The test gives you radioactive iodine, so you don't want to eat a lot of normal iodine, which will dilute the isotope. Avoid seaweed (kelp), dairy, eggs, iodine in vitamins and high salt foods. If the test is for graves or a nodule, it will not matter much. This is more of a concern if the test is for thyroid cancer, or if you are about to receive a treatment dose of radioiodine. ...Read more
HIDA Scan...: 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 moreSee 2 more doctor answers
Cardiac stress test..: A myocardial perfusion scan is used to detect ischemia or infarction (heart attack) and also to evaluation cardiac function (ejection fraction) and ventricular volumes. If there is significant ischemia sometimes a stent can be placed to prevent infarction. ...Read moreSee 1 more doctor answer
See blood flow: Myocardial perfusion studies show the pattern of blood flow (perfusion) to the tissue of the heart muscle. The radiotracer goes where the blood goes and this shows how well the tissue is nourished. It can be an indicator of blocked arteries when the perfusion pattern is abnormal. ...Read more
CAD: The purpose is to diagnose significant coronary artery disease (CAD). If the scan is positive for ischemic changes in the heart, then you will benefit from aggressive medical treatment, angiographic treatment, or surgery. If the scan is negative (and done properly), your risk for CAD or a significant injury such as a heart attack in the next few years is very low. ...Read moreSee 1 more doctor answer
My stress test was abnormal dr said when i was in the middle of the test my blood pressure drop from 180 to 100 and don't know why nuclear test normal?
Been having pain in left bicep and down to forearm on and off for a long while. I've had cardiograms, nuclear test, EKG, all done no problems?
I have my left foot swollen for about 6 months no apparently reason. X-ray, nuclear test, doppler and finally MRI doesn't show anything. Need help!
Unilateral foot : Swelling? I assume it is not painful. It could be lymphedema, caused by anything that interrupts lymph drainage from the foot. If you are diabetic, you could have decreased sensation in the foot and traumatize it repeatedly without knowing, condition called charcot's foot. But not likely with normal mri, which is a very accurate imaging test. I am stumped, sorry. ...Read more
Elevated liver enzymes, fatigue , nausea are my symptoms. Doc suggests gall bladder but nuclear gall bladder test negative. What next?
Had echocardiogram, nuclear stress test w cardiolite, EKG and 30 day holter. Does the echo and nuclear test rule out CAD or any potential blockages?
Is nuclear stress test or Cardiac CTA better for ruling out clogged arteries? My nuclear test was clear but they couldnt do CTA due to heart rate.
Nuclear stress test: The nuclear stress test is better because (1) it is a functional test - your heart is actually "stressed" to beat harder, & (2) you can do it at any heart rate (as you've seen). The cardiac CTA only tells you anatomy - whether or not there is calcium in the arteries - not how your heart functions. Not all plaques contain calcium, either, so cardiac CTA has false negatives also. Talk to your doctor ...Read more

The gallbladder is a sac-like structure located under the right lobe of the liver. It is attached to the common bile duct via the cystic duct. The gallbladder can store bile when the bile is not needed, and can squeeze bile into the bile duct and intestine for digestion when a person eats larger ...Read more
