Bone density scan service (DEXA)

Dual energy X-ray absortiometry (DEXA) scans are used to measure bone mineral density.  This is a common test for osteoporosis.

This service is only available at Purley War Memorial Hospital by appointment only.

Purley Hospital’s diagnostic services can be used by anyone who has been sent by their GP or other medical professional - you need a referral to use
these services. The hospital offers digital X-Ray, DEXA (bone density) and ultrasound scans mostly done by sonographers and can be used as an alternative to travelling to Croydon University Hospital. You will be given an appointment by your healthcare professional to use these services.
