We understand that you might have lots of questions about what to expect when you come for a scan, how to find us or what happens next after your appointment. Please take a look here at the questions we are often asked. If you still have questions, we are happy to help please do not hesitate to get in touch.


  • What is X-ray used for?

    The X-ray examination is able to demonstrate where a foreign object or implant is anatomically in the body, and whether it has any metallic component. X-rays may be requested by our referrers, including our One Stop Clinicians.

  • Is it safe?

    The X-ray room uses ionising radiation when taking an image therefore females of childbearing age will be asked about pregnancy prior to the examination taking place.


  • What is ultrasound used for?

    Ultrasound is a diagnostic tool. Ultrasound utilises high frequency sound waves to create images of internal body parts and structures such as tendons, muscles, joints, vessels and internal organs to look for changes.

  • Is it safe?

    The ultrasound equipment at Cobalt is operated by Specialist Consultant Radiologists and is completely safe.


  • I would like to book myself for a whole body scan for my peace of mind, is that possible?

    Cobalt does not provide health screening scans. If a scan is clinically needed, we require a referral from a medical professional (this can be a consultant, a GP, a physiotherapist, a chiroprator, an osteopath, an extended scope practitioner or dentist).

  • I'm a medical professional, can I refer myself?

    No, we do not accept self-referrals.

  • I'm in pain, can I refer myself?

    We need a medically qualified practitioner to refer you for a scan. This could be a Consultant, GP, Osteopath, Physiotherapist, Chiropractor, Extended Scope Practitioner or dentist.

  • How long will I have to wait for my report?

    Reports are usually completed in 2 working days and sent to your referrer, however we state up to 5 working days to ensure it is received by your referrer within this time.

  • What's the difference between CT and MRI?

    CT is computerised tomography and is used to provide a picture of the structure inside your body. A special type of X-ray machine is used to produce cross sectional images of your body. This involves being exposed to a small amount of radiation. The dose is equivalent to the amount of natural radiation you would receive over a period of three years.

    MRI uses a powerful magnet providing high quality images. Surfaces, cartilage, ligaments and muscles can be seen in greater detail.


  • Is there parking?

    Yes, there is plenty of free parking on site at the Imaging Centre.

  • Do I need to bring my wheelchair?

    Please bring your wheelchair with you. If you are having an MRI scan, you will need to use a special MRI compatible wheelchair when you go through for your scan. These are available from the reception area.
