What To Expect
|
For six hours before your test, do not eat or drink (except
water); do not even chew gum. Your last meal should be high in protein
and low in carbohydrates.
Take medication as prescribed, but if taken with food try to eat a
few soda crackers only four to eight hours prior to your exam. If you
have diabetes, call the Lafayette General Imaging staff at least 48
hours before your appointment.
Most people receive the radiopharmaceutical (called FDG)
intravenously, a procedure that is usually painless. You will then rest
quietly for about 60 to 90 minutes to allow the FDG to distribute
throughout your body. The scan itself will take between 15 and 40
minutes. |
