If I-123 was not available and that is the only reason ever. Some places use Tc99m because it is cheaper and faster than I-123. But i-123 was developed because it was and is better than straight Tc99m
If we didn't have technetium, certain medical imaging procedures like bone scans and heart stress tests would be more challenging as technetium-99m is commonly used in nuclear medicine for diagnostic imaging. Alternative isotopes or imaging techniques would need to be developed, which could be more expensive or less effective. Additionally, research in nuclear physics and related fields may be impacted due to the unique properties of technetium for studying nuclear structure and reactions.
Rhenium is similar to technetium.
Technetium is a man made chemical element.
Technetium is an artificially produced radioactive chemical element (Symbol Tc). It is produced by nuclear fission.It is used to make iron and steel corrosion-resistant.One of its isotopes, Technetium-99m, is very useful in hospital radioactive tests and diagnostic nuclear medicine because of its short half-life (6.01 hours).It was Dmitri Mendeleev who predicted that the missing element in the periodic table would be chemically similar to manganese. And he was right. Manganese appears in the periodic table right above technetium, and the two transitional metals have similar chemical properties. A link is provided to the Wikipedia article on technetium.The element technetium is an "artificial" element. This odd metal has no stable isotopes, so any that existed on earth long ago has decayed and vanished. It was created in experiments in the Berkeley cyclotron facility, but was isolated by a pair of Italian scientists who isolated it from materials sent them from the California facility.Today Technetium is used in making nuclear fuel. It is also a filament for many energy saving light bulbs. Technetium will hopefully be a future replacement for many gas fueled engines such as trains.
I suppose that technetium cannot be bonded with lithium.
technetium may not be natrualy produced but it can still be found in small amounts in the environment. it comes in very small amounts. it can only come from where a nuclear explosion has ocoured, after the nuclear explosion technetium is left behind. but it will not last very long because of its short half life and so will be gone in a short amount of time. the main kinds of explosions that cause technetuim to be in the natural environment would be things such as, nuclear power stations exploding. although now a days this is very rare there have been few explsions, but you may also find it where a neclear bomb has been exploded.
Technetium is one of the rarest elements on the planet. Therefore no one knows if someone is allergic to it and what could cause it.
Technetium is an artificial chemical element and is extracted from fission products, prepared by neutron activation or by irradiation in particles accelerators.

Scrotal nuclear medicine scan is a study of the blood circulation in the scrotum using radioactive contrast agent to highlight obstruction.
One dose of FDA approved potassium iodide will protect the thyroid from radioactive iodine for 24 hours. Nuclear fallout would include a leak from a nuclear reactor or fallout from a nuclear weapon.
