I had a bone scan when I was a kid for a tumor I had in my leg (it ended up being a benign bone cyst, thank goodness!). They used a Technetium 99m injection as a contrast. They had it in a lead covered syringe when they injected into my arm. It's pretty cool knowing I've had such a rare element in my body before. :)

@coopergates9680 2 года назад

I hope they managed to avoid getting much lead into you, though...

@Herobrine_Hoax 2 года назад

You probably still have some! The half life of technetium 99 (not the metastable one) is over 200,000 years, so it would take a very long time for that to decay when the metastable isotope decays into it!

@UNK0VVN 6 лет назад

Just a note, the organic molecule binded with the 99mTc in the radiopharmaceutical doesn't bind to only cancer cells. The radiopharmaceutical concentrates in certain tissues, and since cancer cells have a higher metabolism than healthy cells, it concentrates even more in cancer cells, and that is what gives a suspected diagnosis of cancer. As you can see the in video, the darker regions in the scintigram is where there is a higher concentration of the radiopharmaceutical, but everything that is dark represents activity from the radiopharmaceutical.

When I was in high school, I saw that they were throwing out an old periodic table, and I asked if I could have it, and they said yes! It's really cool -- it's so old that tungsten is still called Wolfram, and there's very little available data on technetium. Unfortunately, it's rolled up because I haven't had wall space for it in a while. It's still cool, though!

I work at Canadian Nuclear Laboratories (formerly Atomic Energy of Canada Ltd) and we irradiated technetium for that exact reason (cancer locating) for about 40 years before being forced by our government to stop. The Cerenkov glow off a "moly rod" is intense! Definitely the coolest thing I have ever been a part of!

2nd correction: Tc in uranium ore does not origin from radioactive decay but from spontaneous fission of U238

@MCNarret 6 лет назад

NuclearSavety wait... isnt that the same thing?

@cleitonfelipe2092 6 лет назад

Narret not really

@gordonrichardson2972 6 лет назад

That depends which isotope of uranium you start with: U235 + neutron in reactors, versus U238 spontaneous fission over very long lifetimes. The exact branching pathway is too complex to describe as part of a short video covering a much broader topic. Decay usually refers to losing one (or a few protons or neutrons) at a time, while fission means splitting into two relatively equal nuclei.

@NuclearSavety 6 лет назад

Well fission is usually an about 1/3rd to 2/3rd split plus some free neutrons... Radioactive decay is usually labeles processes where a core emmits helium-cores (alpha decay), electrons+neutrons+gamma possibly also with antiparticles (beta decay), or a pure gamma decay when an excited core relaxes. With radiactive decay starting from uranium you end up at lead, you dont reach technecium. .

@geocarey 6 лет назад

I had a bone scan last year with Technetium. After the technetium was administered intravenously I had to sit in the hospital cafeteria for a couple of hours. I was told not to sit near any children or pregnant women. After the scan I tried to exit the car park but the parking ticket card malfunctioned and could not be read by the scanner. Could be coincidence, but perhaps I was 'hot' enough to corrupt the magnetic strip?

@croutonicus 6 лет назад

Depending on what scan you had it's likely that the scanner corrupted the strip rather than the Technetium.

@geocarey 6 лет назад

It was a bone scan looking for prostate mets (none found!). During the scan the strip was 15 feet away. The scanner looked for gamma rays so did not emit any of its own radiation.

@poolix1 6 лет назад

geocarey it's unlikely although I'm a radiation therapy student not a nuclear medicine student! I'm surprised they let you sit in the cafeteria to be honest, you still would have been emitting a decent amount

@geocarey 6 лет назад

Apparently I got a dose equivalent to 50 chest X-rays. My first job some 40 years ago was in a radiotherapy centre as hospital physicist. One of my jobs was to prepare Technetium for the patients. Technology has come a long way since then! Little did I know that I would be on the receiving end!

@y_fam_goeglyd 6 лет назад

I had to breathe some as they were looking for microembolisms in my lungs (it worked). The nearest I can describe it is like sucking an exhaust pipe. It's foul! I wasn't allowed near my pregnant daughter or toddler granddaughter for at least a day.

Are there actual agents that bind Tc and specifically bind to tumor targets as the professor implied? As far as I know, Tc is bound to glucose and is transported to regions with high levels of cellular activity, inluding but not limited to tumors. Which is why only fast-growing tumors could be diagnosed with Tc, but not slow-growing ones.

@dimatha7 6 лет назад

Wladyslaw Szpilman Tc99m is just one of the tracers used in nuclear medicine, which organ or tumor will be shown in the exam, depends with what Pharmakon will be bound together.

@erikawanner7355 6 лет назад

@dimatha7 6 лет назад

I think agents are what we here in Germany call Pharmakon. I don't know which Country you are referring that buy the agents from Pharmacy, but here are only bought from huge Pharma Industries and their bound success is 99.99%. The non failure is amazing and a must. 15 years never had a Charge that would not bound within the norms.
