The gamma emission of gallium-67 is imaged by a gamma camera, while the positron emission of gallium-68 is imaged by positron emission tomography (PET). Gallium salts like gallium citrate and gallium nitrate may be used. The form of salt is not important, since it is the freely dissolved gallium ion Ga 3+ which is active. [1]
The mobile phase is a solvent able to elute (wash out) gallium-68 (III) (68 Ga 3+) after it has been produced by electron capture decay from the immobilized (absorbed) germanium-68. Currently, such 68 Ga (III) is easily eluted with a few mL of 0.05 M, 0.1 M or 1.0 M hydrochloric acid from generators using metal-free tin dioxide [ 3 ] or ...
DOTA-TATE can be reacted with the radionuclides gallium-68 (T 1/2 = 68 min), lutetium-177 (T 1/2 = 6.65 d) and copper-64 (T 1/2 = 12.7 h) to form radiopharmaceuticals for positron emission tomography (PET) imaging or radionuclide therapy. 177 Lu DOTA-TATE therapy is a form of peptide receptor radionuclide therapy (PRRT) which targets ...
Among them, the most commercially important radioisotopes are gallium-67 and gallium-68. Gallium-67 (half-life 3.3 days) is a gamma-emitting isotope (the gamma ray emitted immediately after electron capture) used in standard nuclear medical imaging, in procedures usually referred to as gallium scans. It is usually used as the free ion, Ga 3 ...

Instead of gamma-emitting 111 In, certain octreotide derivatives such as edotreotide (DOTATOC) or DOTATATE are able to be linked by chelation to positron-emitting isotopes such as gallium-68 and copper-64 which in turn can be evaluated with more precise (compared with SPECT) scanning techniques such as PET-CT.
Copper (64 Cu) oxodotreotide or Copper Cu 64 dotatate, sold under the brand name Detectnet, is a radioactive diagnostic agent indicated for use with positron emission tomography (PET) for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adults. [2] Common side effects include nausea, vomiting and flushing. [3]
Gallium (68 Ga) gozetotide or Gallium (68 Ga) PSMA-11 sold under the brand name Illuccix among others, is a radiopharmaceutical made of 68 Ga conjugated to prostate-specific membrane antigen (PSMA) targeting ligand, Glu-Urea-Lys(Ahx)-HBED-CC, used for imaging prostate cancer by positron emission tomography (PET).
