FAQ's

General questions

Is there onsite parking?

Body and Bone is in very close proximity to the Bondi Junction Westfield shopping centre so we recommend for convenience that you use this car park.

How far away are you from the train station?

The Body and Bone clinic is an approximate 6 minute walk from the Bondi Junction train station.

Has the Body and Bone clinic moved?

Yes! We were on Oxford St but have relocated to 11a Gray St Bondi Junction in the Full Spectrum Health building. If you walk up the stairs and turn left you will see the clinic room.

Can I book in for an express scan if I have had scans elsewhere or if I do not want/need the consultation?

No. The express scan is for follow up appointments only for clients that have had an initial DEXA scan with us. It is an incentive service that we offer to returning clients only – this service is not available for first time bookings.

DEXA body composition, RMR and BMD questions

Do I need to prepare for my Resting Metabolic Rate Test?

Yes - Please ensure you fast for at least 5 hours which include:

Do I need to prepare for the DEXA scan?

No, we would just recommend to wear light-weight clothing free from metal, buckles and zips. Please come normally hydrated, food consumption is fine we would just recommend no heavy meals right before the scan. When preparing for your follow-up scan try to come in a similar state to the first time you had a scan, in regards to food consumption and hydration.

What is DEXA?

DEXA is an advanced technology originally used to assess bone health. In recent years it has become recognised as the preferred method for body composition assessment in research studies where changes in body fat and/or muscle mass are important.

At Body and Bone Bondi Junction, we use the state-of-the-art Medilink Medix DR DEXA scanner.

How accurate and precise is the DEXA scan for body composition?

The DEXA is seen as the gold standard for determining body composition measurements. It is most commonly used in the medical industry and in research studies. The DEXA has a smaller standard error when compared to other methods such as skinfolds, bioelectrical impedance or underwater weighting. This means the DEXA has a greater accuracy than other methods of measuring body composition.

What measurements do I receive and what do they mean?

A Medilink DEXA body composition scan will give you the following measurements, accurate to one tenth of a gram:

Your scan report will also give us a coloured composition image, which is essentially a visual representation of the fat distribution throughout your body. Fatty areas are shown in the greenish areas, appearing more yellow where the fat holds more density. The blue areas represent lean tissue and appear darker where muscle is denser.

On the report, your bone, lean and fat attributes will allow us to monitor the density weight and area of each region of your body. Your calculated weight and composition percentages will be shown at the base of the report. This will all be explained in detail at any DEXA Body Composition scan + Full Consultation appointments

How long does the DEXA body composition scan and RMR test take?

The DEXA scan itself takes anywhere from 5-7 mins, depending on which type of appointment you book depends on the time of the consultation.

The RMR test takes approximately 15 minutes to perform. The consultation and discussion of results for the RMR can take anywhere between 10 – 15 minutes.

Do I get my results straight away?

For a full body composition scan & RMR metabolic test – yes!

For a bone density scan no, you will be able to obtain these results in about a 5-10 working days from your referring GP. We only perform the test if you have a Dr’s referral in which the results have to be diagnosed through a specialist doctor.

What do I need to wear for a DEXA scan?

It is best to wear comfortable lightweight clothing. Although, it is best to avoid wearing jeans, or anything with metal fixings. You will need to remove any metal before having a scan done.

Only exception is if you have metal screws, etc. that you can’t remove from surgery. If that is the case, you can still get a scan, no problems.

Can I get a DEXA scan if there is a chance I may be pregnant?

No

Can I exercise before the scan?

Yes, you can also exercise before a DEXA scan.

How do breast implants affect the DEXA scan?

Implants will lean out DEXA measurements; they will decrease the body fat. If the implant is filled with silicone, the body fat will be impacted more than if the filler material is saline. As long as the implants remain in the body, the results can be compared. If the implants are removed, a new baseline scan would be required.

How does hydration affect the scan?

It is best to have normal hydration levels for the scan. Water is not fat or bone mineral content and is thus added to lean tissue. If you are extremely dehydrated or fasting for long periods prior to the scan, then this can reduce the total lean tissue values. If you are extremely overhydrated, then this can increase the lean tissue values.

How often should I have a DEXA/RMR/Bone Density scan?

If it’s a body composition scan: it’s a good idea to keep track of your progression every 8-12 weeks, however this all depends on your individual goals.

For an RMR metabolic test, depending on your lifestyle changes (exercise, diet/nutrition/supplements) – every 6-12 months

Bone density tests are usually done once per year.

Is the DEXA scan claimable through my health fund/ medicare?

A DEXA body composition scan is not claimable through medicare/health fund account.

A DEXA bone mineral density scan may be claimable through medicare if you fall under medicare’s criteria based on certain risk factors. You must have a Dr’s referral to be able to have this scan. You will need to check this with your doctor to see if you are eligible.

How much radiation dosage do you get from a DEXA scan?

It is the lowest dosage from any type of x-ray procedure. The radiation exposure is the equivalent you would receive from a return flight from Sydney to Melbourne.

In comparison to other forms of medical imaging, the equivalent would be 1/100th of a chest x-ray

Who should get a DEXA Bone Mineral Density Test?

Ask yourself the following questions to assess your risk:

If you’re over 50 and you answer yes to any of these questions, you should talk to your doctor about your bone health. You will need a Dr’s referral for the DEXA Bone Density test. We are unable to do the scan without this information.
