What is a sestamibi stress test?

A sestamibi (MIBI) scan measures the amount of blood being supplied to your heart. The scan is done in two parts: At rest – sitting and breathing normally. After a chemical or physical stress test – when your heart is beating faster after exercising on a treadmill or exercise bike.

What is Technetium Tc 99m Sestamibi used for?

Technetium 99m sestamibi (MIBI), also known as 99m Tc-methoxy isobutyl isonitrile, is a radiopharmaceutical used to evaluate pathology within the cardiac, breast, and parathyroid tissues. Sestamibi is part of the radioactive diagnostic agents class of medications, characterized as a lipophilic cationic radiotracer.

What is stress myocardial perfusion scan?

Myocardial perfusion is an imaging test. It’s also called a nuclear stress test. It is done to show how well blood flows through the heart muscle. It also shows how well the heart muscle is pumping. For example, after a heart attack, your doctor may order this test to find areas of damaged heart muscle.

Why did my doctor order a nuclear stress test?

The test is done to see if your heart muscle is getting enough blood flow and oxygen when it is working hard (under stress). Your provider may order this test to find out: How well a treatment (medicines, angioplasty, or heart surgery) is working. If you are at high risk for heart disease or complications.

What is sestamibi used for?

Myocardial Imaging: Technetium TC 99M Sestamibi Injection is a myocardial perfusion agent that is indicated for detecting coronary artery disease by localizing myocardial ischemia (reversible defects) and infarction (non-reversible defects), in evaluating myocardial function and developing information for use in …

Is TC 99 radioactive?

Technetium (chemical symbol Tc) is a silver-gray, radioactive metal. It occurs naturally in very small amounts in the earth’s crust, but is primarily man-made. Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions.

What are the pros and cons of using technetium 99m?

It gives high yields of 99Mo of very high specific activity. However, its main disadvantages are high costs and generation of large quantities of highly radioactive waste. Depending on the separation method several types of generators were developed.

Can you drive after a nuclear stress test?

Although you will be receiving a very small dose of radioactive material, certain precautions are advised. Avoid close physical contact with pregnant women and children (ages 12 and under) for 12 hours after the test. 9. You will be able to drive yourself home from this test.
