The collection of frequently asked questions (FAQs) below provides brief answers to some common questions about our Greater Niagara Medical Imaging facilities and services. We continue to add more material to this page as common questions are queried.

Which medical/diagnostic imaging studies are provided at Greater Niagara Medical Imaging?

The medical imaging studies we provide include x-ray, general ultrasound, vascular ultrasound, musculoskeletal ultrasound, and bone mineral density.

Do I need to make an appointment for my medical imaging test?

  • X-rays are performed on a walk-in basis.
  • Ultrasounds are performed by appointment and we will also accommodate urgent cases.
  • If you were to walk-in for an ultrasound study without an appointment we will try our best to accommodate you, however, if we are unable to do so, we will give you the next available appointment

How do I book an appointment?

  • Contact us directly at one of our locations or call us directly. Locations can be found on the menu option of our Website or immediately below each page in the footer section.

What happens if I have to cancel my appointment?

24 hour notice is required for cancellation to avoid a $75 charge.

Are there any instructions to follow to prepare for my study?

Yes. Please refer to the ‘Patient Resource’ section on this website or on the back of your requisition for the necessary instructions.

Do I need to arrive early for my appointment?

We prefer that you arrive 10-15 minutes before your appointment to register.

What happens if I am late for my appointment?

We will make every effort to accommodate you. If that is not possible, we will ensure you get the next available appointment.

Do I need a requisition/referral to get a study performed at Greater Niagara Medical Imaging?

Yes; a signed requisition form is a legal requirement. We accept all types of requisitions or prescriptions and not just our own.

Are there any out-of-pocket costs for my medical imaging study?

No, all medical imaging studies we provide are covered by OHIP. Please make sure you bring a valid health card to your appointment.
