What does a gallium PET scan show?

A gallium scan identifies the cells that are dividing most quickly in your body. It can help detect some cancer cells. It can also help show cells that are rapidly reproducing or responding to an infection somewhere in your body. People with lymphoma (cancer of the lymph system) may need gallium scans.

Is Dotatate safe?

Clinical Trial Experience. The safety of Ga 68 dotatate was evaluated in three single center studies [see Clinical Studies] and in a survey of the scientific literature. No serious adverse reactions were identified.

What is a Dotatate PET scan used for?

This scan is done to diagnose neuroendocrine tumors, which involve both the nervous system and the endocrine glands. For the scan, we will inject a radioactive substance called a tracer into your vein. The tracer used for this scan is called Ga-68 dotatate.

Does a PET scan show all cancers in the body?

PET scans can help diagnose new or recurrent cancer. Cell growth can be detected with a PET scan, but not all cancer types can be seen. Further tests typically need to be performed to complete the diagnosis.

How long does a gallium PET scan take?

Gallium scans take several days between the injection and the actual scan. Sometimes people are scanned more than once after the injection. The scan takes 30 to 60 minutes.

Do neuroendocrine tumors show up on a PET scan?

FDG-PET scan (fluorodeoxyglucose-positron emission tomography scan) FDG-PET can find fast-growing neuroendocrine cancer cells for aggressive tumors. A small amount of FDG, a type of radioactive glucose (sugar), is injected into a vein.

How long does a Dotatate scan take?

This imaging takes about 40 minutes. – If your doctor asked for a whole-body scan (from the top of your head to your toes), the imaging will take about 70 minutes. Expect to be in the Imaging Department for 3 to 3½ hours for your entire PET/CT scan.

Where can I get a GA 68 PET scan?

The Ga-68 scan is not offered at every cancer center. Northern California (NorCal) CarciNET Community, a NET patient support and advocacy group, offers a searchable database to help patients find centers. Roswell Park began offering the Ga-68 PET scan in 2017.

Can a GA 68 psma-11 pet be metastatic?

Among the patients who proceeded to surgery, those with positive readings in the pelvic lymph nodes on Ga 68 PSMA-11 PET had a clinically important rate of metastatic cancer confirmed by surgical pathology. The availability of this information prior to treatment is expected to have important implications for patient care.

Which is better Ga-68 or octreotide PET scan?

Dr. Iyer considers the Ga-68 dotatate PET/CT scan to be superior to an octreotide scan —that uses Indium-pentetreotide —which has been the standard of care. “The octreotide scan is less sensitive, and for many more disease is detected with Ga-68 PET/CT.” The results inform treatment planning.

What can gallium 68 dotatate be used for?

And who stands to benefit most from them? Gallium 68 (Ga-68) dotatate is a radiopharmaceutical tracer used during PET (positron emission tomography) scans. Some PET/CT combination scanners also run a CT (computed tomography) scan in the same session and then merge the images together.
