DEXA scanning

An axial or central DEXA (Dual Energy X-ray Absorbtiometry) scan is a fast, accurate way of assessing bone density. DEXA uses low energy X-rays to help determine if you have osteoporosis or are at risk of developing osteoporosis.

A diagnosis of osteoporosis is essential to prevent life threatening fractures in high risk individuals. DEXA scans can also detect bone-related conditions, such as osteopenia.

Based at East Surrey Hospital, the DEXA service is and is provided by a senior radiographer supported by a team of skilled radiographers with specialist training.  A report of the DEXA scan is made within seven working days by either a consultant radiologist or consultant rheumatologist.
