broadway radiology is the only regional provider of bone densitometry services.
bone densitometry (dexa) is the most accurate, easily accessible method for diagnosing osteoporosis
DEXA scanning (Dual-Energy X-ray Absorptiometry or ‘Bone Densitometry’) is a simple non-invasive technique which uses a very small amount of x-rays to accurately measure bone density and assess an individuals risk of sustaining a fracture. It is a quick and painless procedure for measuring bone loss.
Osteoporosis is the most common of bone diseases. It affects both men and women. Bone loss can occur with age, hormonal changes, disease and with the use of certain medications. Osteoporosis.org.nz
A DEXA Scan may be recommended in the following circumstances:
- If you are over the age of 50 and have suffered a fracture from a minor accident
- Have a family history of osteoporiosis
- If you use medications known to be associated with bone loss e.g. corticosteriods
- If you have Type I diabetes, liver disease, kidney disease or a thyroid condition
- A smoker
You can self-refer for a DEXA and Body Composition scan.
HOW TO PREPARE FOR YOUR bone denistometry scan
- If you take calcium supplements, we do ask that you stop these at least 24 hours prior to your examination as they can affect the results.
- We need to know if you have had any examinations using barium, or have had a CT or nuclear medicine scan which involved having an injection. You will need to wait at least 2 weeks before having your DEXA scan as these will affect your results.
WHAT HAPPENS DURING YOUR EXAMINATION
- You will be asked to fill in a questionnaire about your bone health history.
- You will also be weighed and your height recorded. The machine uses these measurements in its calculation of your bone density.
- You may be asked to change into a gown.
- Scans will be acquired of your lower back and one of your hips.
- If there are reasons why your back or hip cannot be scanned (e.g. previous fractures in those areas, a hip replacement or spinal surgery) then a scan of your forearm may also be done.
AFTER YOUR EXAMINATION
- The DEXA scan is reported by our Radiologists. The report will then be sent to your referring health professional who can discuss your results with you.
- The Radiographer is responsible for performing the DEXA scan. They are not qualified to provide interpretation. If you wish to clarify your result, please either contact your referring doctor or call us here at Broadway where a Radiologist can assist you.
