What is a BONE MINERAL DENSITOMETRY (DEXA) Examination?

 

A Dual Energy X-ray Absorption (DEXA)  scan uses a thin beam x-ray source to assess bone mineral denisity (BMD) and is used to diagnose osteoporosis. Decreased BMD (osteoporosis) increases the chance of low impact fractures which are commonly seen in elderly people, post menopausal women and in patients with a history of prolonged steroid use.

 

Who Can Claim A DEXA scan Through MEDICARE?

 

DEXA scan may be bulk billed if they satisfy any of the Medicare criteria as described below:

  • Older than 70 years old
  • Menopause, hysterectomy and/or oophorectomy before 44.5 years of age
  • Male hypogonadism
  • Long term steroid treatment
  • Fracture with minimal trauma
  • Crush fracture of more than 20%
  • Follow up of previously diagnosed low bone density
  • Chronic diseases that may have an impact on bone density such as chronic liver or kidney disease

DEXA scans can be performed between 8:30am-5:00pm Monday to Friday and 9:00am-1:00pm Saturday.

No appointment is required.

A thin beam of x-ray energy is passed through both the lower spine and hip regions of the body. Low doses of radiation are used. You will be asked to lie down whilst the scanner makes multiple passes across you.
A computer calculates how much of x-ray energy is absorbed by the bones and compares the results to that of a younger person, along with what is commonly expected of a person of a similar age and sex.

Our DEXA scanner affords an extensive scan area, shorter examination times and increased patient comfort.

This test does not require fasting.
Calcium supplements or Tums can interfere with exam results. To avoid this potential problem, do not take calcium supplements or Tums within 24 hours of your exam.
Medications containing magnesium can also interfere with exam results. To avoid this potential problem, do not take any medications such as Milk of Magnesia, Maalox, Pepto Bismol or Kaopectate the day of the appointment.

Patients who take one of these products on the day of the exam will need to be rescheduled.

Please do not wear clothing that contains metal to your exam as the metal will interfere with exam results.

How long is the procedure?

The procedure takes approximately 20 minutes.

Are there any side effects or risks associated with a DEXA Scan?

Radiation dose for all x-ray procedures are kept as low as possible. I-rad adheres to the ALARA (as low as reasonably achievable) principle, and complies with all national standards relating to radiation dose.

If you are pregnant or unsure if you might be pregnant, please let staff know prior to your examination as x-rays may have an effect on your unborn baby.
