What is Technetium Tc 99m Medronate used for?
Radiopharmaceuticals are radioactive agents, which may be used to find and treat certain diseases or to study the function of the body’s organs. Technetium Tc 99m medronate injection is used to help your doctor see an image of your bones to help diagnose bone problems.
What are the side effects of TC 99?
Common side effects of Neotect include:
- headache.
- dizziness.
- nausea.
- flushing (warmth, redness, or tingly feeling)
- back pain.
- chest pain.
- diarrhea.
- fatigue.
What is the difference between technetium-99m and technetium 99?
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.
What are the limitations of 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.
What are the benefits of technetium-99m?
Technetium-99m Benefits
- The principal benefit of this radioactive substance is its long half life. 6 hours is long enough for various medical examinations to be done.
- The radiation dose to the patient remains low because 99mTc emits gamma-ray.
- 99m
- It emits the 140 keV gamma rays, which is readily detectable.
Why is element 43 unstable?
Technetium is a radioactive element, with no stable isotopes. With an atomic number of 43, it is the lightest unstable element. The short answer is that there is no number of neutrons you can put in a technetium atom to form a stable nucleus.
Why is technetium unstable?
Technetium can only be produced artificially because most forms or isotopes of it (atoms of the same chemical element with different numbers of neutrons) have an excess of neutrons, making it very unstable.
Why does technetium 99m have a short half-life?
Technetium-99 has a fission product yield of 6.0507% for thermal neutron fission of uranium-235. The metastable technetium-99m (99mTc) is a short-lived (half-life about 6 hours) nuclear isomer used in nuclear medicine, produced from molybdenum-99….Technetium-99.

How is technetium used in medicine?
The metastable isotope technetium-99m (6-hour half-life), used with radiographic scanning devices, is valuable for studying the anatomic structure of organs. Technetium is also used as a metallurgical tracer and in corrosion-resistant products.
Is technetium used in medicine?
A technetium injection contained in a shielded syringe. Technetium-99m is a metastable nuclear isomer of technetium-99 (itself an isotope of technetium), symbolized as 99mTc, that is used in tens of millions of medical diagnostic procedures annually, making it the most commonly used medical radioisotope.
What is the half life of TC 99?
Technetium TC-99m is one of the radioactive isotopes of technetium, a gamma/beta-emitter with a half life of 6 hours. CEA-Scan is indicated only in patients with histologically-demonstrated carcinoma of the colon or rectum for imaging of recurrence and/or metastases.
