Any side effects from sestamibi?

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 more

Is it important to take msct scan or sestamibi test after taking catheterization? Is there anything these 2 tests can show that catheterization cant?

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

What is the sestamibi stress test?

What is the sestamibi stress test?

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 more

What is the sestamibi treadmill stress test?

What is the sestamibi treadmill stress test?

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 more

What is the role of a thyroid sestamibi scan in detecting or to rule out thyroid malignancy?

What is the role of a thyroid sestamibi scan in detecting or to rule out thyroid malignancy?

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 more

What is the persantine sestamibi stress test?

What is the persantine sestamibi stress test?

See below.: This is a chemical stress test of blood flow to the heart muscle. It is used to evaluate patients who are unable to exercise. Pictures of blood flow are obtained before and after the stress. Post stress abnormalities may indicate narrowings of the coronary arteries which impede blood flow and may be a cause of chest pain. Abnormalities of flow before stress may indicate previous damage. ...Read more

What is the sestamibi stress test with adenosine?

What is the sestamibi stress test with adenosine?

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 more

Could sestamibi nuclear stress test only evaluates left ventricular function?

NO: Nuclear stress test are done to evaluate coronary circulation/ blockages/CAD. As lagniappe they provide info re LV function. However, there are less expensive and invasive test that evaluate LV function just as well or better, like echocardiography ...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

How is a persantine sestamibi stress test performed?

How is a persantine sestamibi stress test performed?

Pharmacologic stress: Often we use other agents but Persantine is injected and the patient is either imaged soon after or after a little exercise, after the Persantine administration, sestamibi is injected to allow the imaging. ...Read more

Is it normal to have normal ultra sounds of my thyroid and a normal sestamibi but abnormal blood work?

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 more

Can I make sestamibi scan for parathyroid although imy leucocyte count is below normal its 3700 or it will be a risk?

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

I recently had a parathyroid scan. The findings were : Slightly asymmetric retention of sestamibi within the right thyroid region of the planar image?

I recently had a parathyroid scan. The findings were : Slightly asymmetric retention of sestamibi within the right thyroid region of the planar image?

Parathyroid scan: What is missing from your question is why the doctors are checking on the parathyroid glands.
Did your doctor measure a few things related to the parathyroid?

Parathyroid has been my "hobby" since 1974 -
What does your doctor mean by "slightly asymmetric. ..?
Have you had blood drawn to measure parathyroid hormone levels?

Please keep me posted. ...Read more

What this means? Myocardial perfusion imaging with Tc-99m Sestamibi after exercise revealed no scintigraphic evidence of hemodynamically significant ischemia. Medium-sized, mid to basal inferior wall mild-to-moderate mostly fixed perfusion deficit, excep

Stress test: A stress test with myocardial perfusion imaging is a way of detecting whether the heart muscle is getting insufficient blood supply because of coronary artery disease. It can be normal even with lots of coronary plaque, because it only detects severe narrowings. If there is a "fixed" perfusion defect that generally suggests a scar in the heart muscle from prior heart attack. Need more info. ...Read more

My TSH is 5.35, thyroid peroxidase is 329 and my free T4 is 1.2. Do I need medicine. Also sestamibi scan shows I have adenoma.

My TSH is 5.35, thyroid peroxidase is 329 and my free T4 is 1.2. Do I need medicine. Also sestamibi scan shows I have adenoma.

Hashimoto's: Hi. You have subclinical Hashimoto's by those labs. Who did a sestamibi scan for your thyroid? We don't do that in the US...oh, wait...you ARE in the US! Sestamibi scan can show a "cold" area, but CANNOT diagnose an adenoma. That takes cytology or surgical biopsy. As for treatment, in my opinion, there is no reason to wait for you to become symptomatically hypothyroid to start thyroid hormone. ...Read more
