Tin-117m (117mSn)
Properties: Tin-117m (117mSn) is both a gamma (SPECT) emitter with a photon at 159 keV (86%) and a therapeutic radionuclide through conversion electrons at about… Read More »Tin-117m (117mSn)
Iodine-123 (123I)
Its nuclear properties are also almost ideal for SPECT studies. In parallel, the radionuclide 123I is a halogen and thus a very useful analog label… Read More »Iodine-123 (123I)
Indium-111 (111In)
Indium-111 is a radioactive isotope of the element indium with a half-life of approximately 2.8 days. It is commonly used in nuclear medicine for imaging… Read More »Indium-111 (111In)
Gallium-67 (67Ga)
The trivalent metallic radionuclide 67Ga is produced via (p,2n) reactions, on 68Zn. For production on a smaller scale, the (p,n) reactions on 67Zn have also… Read More »Gallium-67 (67Ga)
Thallium-201 (201Tl)
Properties:Thallium-201 (201Tl) is a SPECT radionuclide decaying in 72.9 hours with a gamma emission at 167 keV (10%) but also beta emissions at 316 keV… Read More »Thallium-201 (201Tl)
Technetium-99m (99mTc)
The pair 99Mo (t½= 66 h)/99mTc (t½= 6 h) represents a transient equilibrium system. The radiochemical general design of a 99Mo/99mTc generator is to absorb 99Mo as… Read More »Technetium-99m (99mTc)
