How you prepare

By Mayo Clinic Staff

To prepare for a low-dose CT scan, you may need to:

  • Change into a hospital gown. You may be asked to remove your shirt and change into a gown.
  • Remove any metal you're wearing. Metals can interfere with the imaging, so you may be asked to remove any metal that you might be wearing, such as jewelry, glasses, hearing aids and dentures.
