Hip and Spine (Osteoporosis diagnosis)
A DEXA examination of the HIP and SPINE is most commonly used for an Osteoporosis diagnosis because these are two areas at high risk of an Osteoporotic fracture. This is known as an ‘axial’ or ‘central’ scan and measurements of bone density at these sites are the best at predicting who is at risk of having an Osteoporotic fracture. The results help to identify who should be treated for Osteoporosis and enable monitoring of the response to treatment. The scan involves lying on a firm couch whilst a scanning arm passes over the body taking an image of the spine and hips. It does not involve being enclosed in a mechanical tunnel or having an injection. Generally, clothing does not have to be removed but clothes with metal (underwired bra, trousers with zip) should be avoided.
Hip Spine and Forearm
An enhanced DEXA examination involving a scan of your HIP, SPINE and FOREARM may be required if you have certain medical conditions (e.g. hyperparathyroidism, severe kidney disease) or an Osteoporosis diagnosis, or if you are unable to lie on an examination table to have your spine and hip scanned successfully. The scan does not involve being enclosed in a mechanical tunnel or having an injection. Generally, clothing does not have to be removed but clothes with metal should be avoided.
