Hm, I live in Ohio. We just call the mammogram center (any you are interested in) and get it done. WE schedule the appointment, no referral needed. Doctor doesn't schedule it, we do. It's not a regular doctor's office. It's a mammogram imaging center. In fact, we have mobile mammogram busses that travel to different places weekly and you can hop on and get a mamo that way. So, put into your search bar, mammography in Detroit and you will get lots of results and have your wife make some calls and set it up. good luck
