What is the difference between TC-99 and TC-99m?

Technetium-99 is produced during nuclear reactor operation, and is a byproduct of nuclear weapons explosions. Technetium-99m is a short-lived form of Tc-99 that is used as a medical diagnostic tool. It has a short half-life (6 hours) and does not remain in the body or the environment for long.

How does Tc-99m work in the body?

WHAT IS TECHNETIUM-99m USED FOR? Technetium-99m decays by a process called isomeric transition, a process in which 99mTc decays to 99Tc via the release of gamma rays and low energy electrons. Since there is no high energy beta emission the radiation dose to the patient is low.

Is Tc99m safe?

Technetium-99m has a photopeak of gamma-ray emission of 140.5 keV, making it a very minimal risk of toxicity. [3] The short six-hour half-life and rapid excretion from the body limit toxic effects and give enough time to perform its diagnostic imaging, all while limiting radiation exposure to the patient.

Can I drink coffee after nuclear stress test?

Caffeine can alter the test results. Do not eat chocolate or drink coffee, tea, soda, colas or other caffeinated beverages such Mountain Dew or energy drinks. If you are unsure, do not drink it.

How does Tc 99m Show cardiac damage?

Tc-99m can be used to look at cardiac damage. The isotope flows in the blood stream; if there is less blood flow in the heart, there will be less isotope concentrated in the heart muscle. Similar information can be obtained for blood flow in the brain.

Why is tc99m used in medicine?

Tc-99m is the preferred tracer for a number of scans used in medicine worldwide to help diagnose medical conditions. Tc-99m scans are used to detect a wide range of conditions including injuries, infections, tumours, heart disease, thyroid abnormalities, kidney conditions and also to guide some cancer procedures.

How much does it cost to produce technetium 99m?

In other words, the cost for producing Mo-99 probably range from about $125 to $325 per 6-day curie. The overall cost of producing 12,000 6-day curies of Mo-99 per week to meet 2006 demand at $225 per 6-day curies is about $140 million.

Do you have to eat Big to get big to gain weight?
