WebMRI. MRI scans can cost from as little as £200 per body part up to over £500 per body part depending on the scanner/ scan centre. You would normally receive a discount for additional body parts which means for an MRI scan of both knees you would normally pay for one knee + a discounted price for the second knee e.g. £300 + £150 = total £450. WebA DEXA scan (dual-energy X-ray absorptiometry) is an imaging test that measures density (strength) of your bones. This is done by using very low levels of x-rays and measuring the mineral content of the bones in certain areas of the skeleton. The results can provide details about your risk for osteoporosis (bone loss) or bone fractures.
