Osteoporosis screening measures the density of your bones (which is related to bone strength) by performing bone density scans. You'll need to lay on a scanning bed for this procedure. We use very small amounts of X-rays and usually scan your lower spine and 1 hip. From this, we'll be able to assess whether you have or are likely to develop osteoporosis.

Opening times: Monday, 2pm to 5pm

Our thyroid clinic offers treatments for non-cancer thyroid conditions including those with radioactive iodine.

New patients

If you're a new patient to the clinic, we might order a thyroid scan before your consultation. This is a test to look at the size, shape, position and activity levels of your thyroid gland.

The scan involves an injection of a very small amount of radioactive tracer and then a wait of about 20 minutes for your thyroid gland to absorb it. Then you'll have a scan of your thyroid. During the scan you'll lie on an imaging bed and the scanner will come close to your face but will not touch you.

You don't have to remove your clothing but any necklaces must be taken off. A staff member will stay in the room with you at all times. The scan does not have any side effects.

Our doctor will review these scans and talk to you about the results on the same day.

Existing patients

You'll see a consultant who will review your medicines and order a blood test to monitor response to treatment. They'll check that you are on the correct dose of thyroxine.

After the consultation and blood test you can leave the hospital. Our consultant will write to you and your GP once the blood test results are reviewed. This is usually within 1 week.
