FDA approves production of imaging agent that helps detect prostate cancer

The U.S. Food and Drug Administration recently approved the production and use of Choline C 11 Injection, a Positron Emission Tomography (PET) imaging agent used to help detect recurrent prostate cancer.

Choline C 11 Injection is administered intravenously to produce an image that helps to locate specific body sites for follow-up tissue sampling and testing in men with recurrent prostate cancer.

PET imaging with Choline C 11 Injection is performed in patients whose blood prostate specific antigen (PSA) levels are increasing after earlier treatment for prostate cancer. An elevated PSA result suggests that prostate cancer may have returned, even though conventional imaging tests, such as computerized tomography (CT), have not shown any signs of cancer. PET imaging is not a replacement for tissue sampling and testing.
