Any Side Effects From Sestamibi
Rare: People rarely have side effects from the tracer sestamibi. It is more likely to have side effects from other agents used during cardiac stress if you are having a pharmacologic stress. The pharamacologic agents can cause side effects but usually sestamibi is not the culprit. ...Read moreSee 2 more doctor answers
Is it important to take msct scan or sestamibi test after taking catheterization? Is there anything these 2 tests can show that catheterization cant?
Sometimes: Cath reveals the size of the arteries to the heart. Nuclear tests can demonstrate whether the heart muscle is receiving adequate blood supply. This may help in determining whether a partial blockage is causing a problem. Thus the data from the 2 tests can be complimentary and give a more complete picture of the clinical situation. ...Read more
Not for thyroid CA: Sestamibi scans are not indicated for thyroid cancer evaluation. It will very rarely reveal a thyroid cancer. It would only be indicated if your doctor suspected a very rare neuroendocrine tumor or a parathyroid tumor (after checking calcium and PTH and confirming they are both elevated). ...Read moreSee 2 more doctor answers
See below: A sestamibi stress test is used to detect decreases in blood to the heart muscle during exercise or chemical "stress." such decreases in flow may indicate partial or complete blockage of one or more of the coronary aeries that supply blood to the heart muscle. ...Read moreSee 1 more doctor answer
Is it normal to have normal ultra sounds of my thyroid and a normal sestamibi but abnormal blood work?
Yes: Sestamibi scan should have been ordered if you had high serum calcium and high PTH and urine calcium is not low. It shows the abnormal parathyroid only 85 % of the time. The ultrasound is less likely to show an abnormal parathyroid and very dependent upon the person performing the ultrasound. ...Read moreSee 2 more doctor answers
Nuclear study: This is a nuclear medicine test that tells your physician about your heart function. A small amount of nuclear tracer is given right after/during running on a treadmill followed by a scan. This is compared to a similar scan performed at a separate time under resting conditions. Any decreased area of tracer uptake in the heart during stress compared to rest indicates a possible artery block. ...Read moreSee 1 more doctor answer
MPS: I believe you are referring to a myocardial perfusion scan, where technitium sestamibi 99 is the radioactive isotope that is injected intravenously so that images can can be taken of the heart at rest and 'stressed' or exercrsing -which brings us to the adenosine: a pharmacological agent used to 'stress' the heart instead of walking on a treadmill. Lexiscan is the stress agent of choice now. ...Read moreSee 1 more doctor answer
Can i make sestamibi scan for parathyroid although imy leucocyte count is below normal its 3700 or it will be a risk ?
If you need it yes: A sestamibi parathyroid scan or MIBI is very safe as the amount of radiation is small & localizes to metabolic active tissue such as the overactive parathyroid. Very little bone marrow exposure. If adenoma thought to be in neck high sensitivity US can be a substitute & has no radiation. Other options also exist. A MIBI IS NOT FOR DIAGNOSIS, but surg planning! Make sure it is for the right reason! ...Read more
Msct scan, catheterization and sestamibi test results all show the blood flow in arteries. What are the main difference between these test results?
See below: Cath is the gold standard to which any procedure is compared to but is invasive. Msct is non invasive and evaluates the vessel specifically and can assess the degree of stenosis/blockage. Drawbacks include : 1)potentially higher dose of radiation but is significantly reduced at experienced centers2) overestimation of stenosis in inexp hands and artifact. Sestamibi only looks at blood flow. ...Read more
