Gallium-68, which has a 68 minutes half-life, is produced in a gallium-68 generator by decay of germanium-68 with a 271 day half-life or by the irradiation of zinc-68 through a low energy cyclotron. Use of a generator means a supply of 68 Ga can be produced easily with minimal infrastructure, for example at sites without a cyclotron , commonly ...
An octreotide scan is a type of SPECT scintigraphy used to find carcinoid, pancreatic neuroendocrine tumors, and to localize sarcoidosis. It is also called somatostatin receptor scintigraphy (SRS). Octreotide , a drug similar to somatostatin , is radiolabeled with indium-111 , [ 1 ] and is injected into a vein and travels through the bloodstream.
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). [11]
The use of metal-free columns allows direct labeling of 68 Ga without prepurification, hence making production of gallium-68-radiolabeled compounds more convenient. 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.
A PSMA scan is a nuclear medicine imaging technique used in the diagnosis and staging of prostate cancer. It is carried out by injection of a radiopharmaceutical with a positron or gamma emitting radionuclide and a prostate-specific membrane antigen (PSMA) targeting ligand .
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 ...
