Do we need to know specific radioisotopes (1 Viewer)

[Alex S]

Hey guys,

for the point "outline properties of radioative isotopes and their half lives that are used to obtain scans of organs" in the radioactivity section of medical physics, do i just need to know about these properties in general for all radioisotopes used in medical imaging, or do i need to be able to relate them to specific radioisotope examples and why they are used?

Thanks for the help.

relate them to specific radioisotope examples and why they are used

Just get a couple, e.g iodine-131

I don't do Phy... but i'd suggest Technetium-99m. It releases low-energy gamma radiation, when it downgrades from a metastable state. It has a half-life of 6 hours, and since it emits low-energy gamma radiation... does not expose the body to harmful radiation for long periods. It's multiple oxidation states allow it to attach to many biological molecules (such as glucoheptonates for brain and renal scanning, and phosphonates for bone scanning).
Tc-99m is commonly used as a medical radioisotope in diagnostic imaging.

yeh i do both iodine-131 and technetium-99m.
they are both easy, and can be done for chemistry too...

so many dot points overlap in the 3 sciences..its awesome

Are Iodine-131 and Technetium-99m used both in PET scans and Bone scans?
