What is Gallium Ga 68 used for?

Gallium Ga 68 dotatate injection is used with a PET scan (positron emission tomography) for localization of somatostatin receptor positive neuroendocrine tumors (NETs) in adults and children.

What is a gallium 68 scan?

A Ga-68 dotatate scan is a test used to check the body for the presence of neuroendocrine tumor cells. You will have this test done in the Nuclear Medicine department. Nuclear medicine is a type of radiology that uses radioactive materials to diagnose or treat diseases.

What is the normal biodistribution for GA 68 Dotatate?

For adults, the administered activity of gallium-68 DOTATATE ranges from 100 to 200 MBq (2.7 to 5.4 mCi), average 150 to 185 MBq (4 to 5 mCi), given as a single IV bolus.

Is gallium 68 FDA approved?

Today, the U.S. Food and Drug Administration approved Gallium 68 PSMA-11 (Ga 68 PSMA-11) – the first drug for positron emission tomography (PET) imaging of prostate-specific membrane antigen (PSMA) positive lesions in men with prostate cancer.

How much does a gallium-68 scan cost?

As of July 2016, the US FDA has approved the use of 68-Gallium DOTATATE for PET imaging for both adult and pediatric patients and the imaging modality has become widely available in the USA. The cost of the imaging modality is about USD$4,000.00 and this cost is not yet routinely covered by insurance companies.

How does Gallium-68 decay?

Gallium-68 is a positron emitter that decays with a half-life of 67.71 min and 89% positron branching to stable zinc-68. The transition is accompanied by low-abundant photon emission (1077 keV, 3.22%) [23].

How much does a gallium 68 scan cost?

What is the half life of gallium 68?

68 min
The convenient half-life of 68Ga (T1/2=68 min) provides sufficient radioactivity for various PET imaging applications, while delivering acceptable radiation doses to patients.

Who makes GA 68 PSMA?

Telix Pharmaceuticals
1, 2020, the approval of UCLA/UCSF sponsored Gallium 68 PSMA-11 (68Ga PSMA-11), the first diagnostic based on PET imaging of prostate-specific membrane antigen (PSMA) for prostate cancer patients,1 Telix Pharmaceuticals was already preparing for the anticipated increase in demand for gallium.

How long does a gallium-68 scan take?

The Gallium-68 PET/CT for neuroendocrine tumors looks like this: Not only does this scan show these tumors, it is also much faster than the older scan, and can be done during a single appointment of two to 2.5 hours.

How long does gallium stay in your system?

The scan uses a small amount of radiation. Although large amounts of radiation can increase your risk of cancer, the exposure from a gallium scan is very small. It’s less than what is used for many types of X-rays. Your body naturally clears the gallium from your system over several days.
