During Your Exam

  • Your approximate visit time will be 3-4 hours.
  • Upon arrival, the technologist will explain your procedure and answer any questions you may have.
  • You will receive an intravenous injection (in your vein) of a tracer dose of radioactive material.
  • The level of radioactivity is extremely low and has no side effects.
  • You will be asked to wait approximately 1-2 hours before the scan begins.
  • Your scan will take approximately one hour.
  • During that time you will be required to lie flat on your back, without moving.
  • Using a special nuclear medicine scanner, pictures of your body will be obtained. The scanner does not produce any radiation; it simply detects and records the distribution of the radioactive material in your body.

After Your Exam

There are no post-exam instructions.

Your study will be reviewed by an imaging physician specialist and the results sent to your physician. Your physician will discuss these results with you and explain what they mean in relation to your health.
