Prostate cancer scanning: Photos from inside Mayo's lab

Science

1 Ping Fang, a senior chemist in Radiology at Mayo Clinic, monitors the production of C-11 methyl choline in a lab Wednesday, Nov. 28, 2012 at Mayo Clinic in Rochester, Minn. C-11 choline is an agent used during PET scans to help detect reoccurring prostate cancer. The Mayo Clinic is the only health facility in the U.S. currently approved by the FDA to administer Choline during PET scans, and they plan to expand their production and services to offer it to more patients.

C-11 choline, which is an agent used during PET scans to help detect reoccurring prostate cancer, is isolated because a radioactive marker is added to it to the production process.

6 Larry Weber, 58, of Olney, Ill. prepares for a PET scan Wednesday, Nov. 28, 2012 at Mayo Clinic in Rochester, Minn. Weber was being scanned using C-11 choline to check for a recurrence of prostate cancer. Weber was diagnosed with an aggressive form of the cancer in 2006 and said he has since experienced 37 rounds of radiation, chemotherapy and hormone deprivation. 
7 The C-11 choline agent is injected into Larry Weber Wednesday, Nov. 28, 2012 at Mayo Clinic in Rochester, Minn. C-11 choline is an agent used during PET scans to help detect recurring prostate cancer. Because of C-11 choline's short half-life, it must be administered shortly after production.
