The Biodistribution and Potential Diagnostic Ability of 18F FACBC in Patients With Head and Neck, Breast, and Prostate Cancer

Two IV catheters (heplock) will be placed in your forearms for injection of the dye-like material (FACBC) and blood sampling. An IV blood sample and a urine sample will be taken for testing. These samples will be used to measure the dye, FACBC, in blood and urine. You will be placed in the PET machine, where FACBC will be injected slowly over 30 seconds. Pictures of one region of your body will be taken for up to 60 minutes. Depending on your condition, your actual picture time may be shorter. You will come out of the scanner to stretch, walk around or sit in a chair. An optional urine sample and an IV blood sample will also be taken at this time. Again, these samples will be used to measure the dye, FACBC, in blood and urine. This will be followed by a picture of your body from the neck to the upper thighs. This picture will take about 30 minutes.
