How do you prepare for a bone density test?
How to Prepare
- Don’t take calcium supplements for 24 hours before the exam.
- If you’ve had an injection of barium or contrast dye for a CT scan or MRI, wait 7 days before having a central DXA. The contrast dye could interfere with your bone density test.
- Avoid wearing clothes with metal zippers, belts, or buttons.
What should you not do before a DEXA scan?
On the day of the exam you may eat normally. You should not take calcium supplements for at least 24 hours before your exam. You should wear loose, comfortable clothing, avoiding garments that have zippers, belts or buttons made of metal.
How do you perform a DEXA scan?
How does a DEXA scan work?
- You will be asked to lie on a special DEXA x-ray table.
- As the arm of the DEXA machine passes over the body, IT uses two different x-ray beams.
- The scanner translates the bone density measurement data into pictures and graphs.
How do I prepare for a DEXA body composition scan?
Whole Body DEXA Scan Preparation
- Refrain from eating solid foods for 1-2 hours prior to your scan.
- Maintain normal hydration.
- Wear clothing with minimal metal components (i.e buttons, zippers, etc.)
- If you have a medical device implant such as a pacemaker, prosthetic device, joint replacement, etc.
Can I wear a bra for a bone density test?
Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra. Gowns are available, if necessary.
Can I drink milk before bone density test?
Do NOT eat foods high in calcium for 3-4 hours before your DXA scan. These foods include: milk, cheese, yogurt, and dark green leafy vegetables. Do NOT take calcium supplements, vitamins, or TUMS® on the day of your scan.
Can you wear a bra for a DEXA scan?
Patients should not have had a barium study, radioisotope injection, or an oral or IV contrast material from a CT scan or MRI within 7 days prior to their DEXA exam. Patient should wear loose, comfortable clothing. Sweat suits and casual attire without zippers, buttons, grommets, metal hooks, or underwire bra.

What is a bad DEXA scan score?
It is important to understand a T score of -1 and above is perfectly normal once over 50. A T score between -1 and -2.5 indicates lower than normal bone density for age – this is referred to as osteopenia. A score lower than -2.5 indicates significant bone loss – 25% or more and this is classified as osteoporosis.

Do you have to take your clothes off for a bone scan?
No special preparations are needed. You may be able to remain fully clothed, depending on the area of your body being scanned. But you’ll need to remove any clothes that have metal fasteners, such as zips, hooks or buckles. In some cases, you may need to wear a gown.
How does the digit-x x-ray densitometer work?
Digit-X is a unique hand-held transmission X-ray Densitometer combining ease of use with high accuracy and repeatability. The fine fibre-optic probe allows small areas of film to be measured accurately with readings being displayed on the large clear LCD panel to 2 decimal places. Digit-X can reliably read film densities up to a maximum of 4.0D.
What are step by step instructions for densitometer?
(b) The densitometer manufacturer’s step-by-step instructions for the operation of the densitometer shall be followed. (c) The density steps closest to 1.0, 2.0, 3.0, and 4.0 on the national standard step tablet or step wedge calibration film shall be read.
How often do densitometers need to be calibrated?
Densitometers shall be calibrated at least every 90 days during use as follows: (a) A national standard step tablet or a step wedge calibration film, traceable to a national standard step tablet and having at least 5 steps with neutral densities from at least 1.0 through 4.0, shall be used.
How is the density of a step calibrated?
Remove the film from its protective sleeve and place the center of a step on the diffuser of the densitometer to be calibrated with the side of the step tablet with the serial number in contact with the diffuser. Calibrate the densitometer using the transmission density of that step, and repeat this procedure with other steps of the step tablet.
