Baptist Health Diagnostic Imaging offers a precise, low dose procedure known as a DEXA scan to measure bone strength and mineral content. This quick and comfortable exam helps clinicians detect bone loss early, often before a fracture occurs.
By using dual energy x-ray absorptiometry, the scan delivers detailed images of the spine, hip, and sometimes forearm, providing objective data to guide prevention and treatment plans. Below is a quick reference to what you can expect.
| Exam Name | Common Sites | Duration | Radiation Dose | Primary Purpose |
|---|---|---|---|---|
| DEXA Scan (Bone Density) | Lumbar spine, hip, forearm | 15–30 minutes | Very low (≈0.01 mSv) | Diagnose osteoporosis, assess fracture risk |
| Preparation | N/A | Minimal prep | N/A | Avoid calcium supplements 24 hours, wear loose clothing, no metal zippers |
| During Exam | Table with imaging arm | 10–20 minutes under scanner | Low dose targeted imaging | Lie still while arm passes over targeted areas |
| Results and Reporting | T-score, Z-score | 1–2 business days | Radiologist interpretation | Compare to young adult and age-matched peers |
Understanding DEXA Technology and How It Works
DEXA uses two x-ray beams at different energy levels to distinguish bone from soft tissue, allowing precise measurement of bone mineral density. The scanner moves slowly over the body while a low dose of radiation captures detailed images.
This method is highly accurate for monitoring changes over time, making it ideal for tracking response to therapy or early intervention. Baptist Health facilities integrate this technology with board certified radiologists for reliable reporting.
Who Should Consider a Bone Density Test
Certain factors increase the likelihood of bone loss and make screening more important. Age, gender, family history, and hormone changes all contribute to risk levels that clinicians consider when recommending a DEXA scan.
- Women aged 65 or older and men aged 70 or older
- Adults with a fracture after minimal trauma
- Individuals with long term steroid use or certain medical conditions
- Patients experiencing height loss or spinal curvature suggestive of vertebral fracture
What to Expect During Your Exam
On the day of your appointment, you may be asked to change into a gown and remove items with metal. The technologist will position you on the padded table and guide you through each step so you remain comfortable and still.
You will hear quiet clicking as the scanner arm moves above you, but there is no sensation from the imaging process itself. Most people complete the test without discomfort and are free to resume normal activities immediately.
Interpreting Your DEXA Results
Results are expressed with T-scores and Z-scores that compare your bone density to reference populations. A T-score of minus 1.0 or above is considered normal, while lower values indicate lower bone density.
Your physician will correlate these numbers with your overall health, fracture history, and other risk factors to determine whether medication, lifestyle changes, or further monitoring is appropriate. Regular follow up scans can show whether treatment is helping to maintain or improve bone strength.
Scheduling and Next Steps with Baptist Health Diagnostic Imaging

- Discuss bone density screening with your primary care provider or specialist
- Verify insurance coverage and any referral requirements before your appointment
- Follow prep instructions carefully to ensure accurate results
- Ask about timing for results and how they will be communicated to you
- Keep records of your scans and reports for long term bone health tracking
FAQ
Reader questions
Is a DEXA scan safe during pregnancy or for frequent monitoring?
While the radiation dose is very low, DEXA is typically avoided during pregnancy unless clearly necessary. For frequent monitoring, your care team will schedule exams at appropriate intervals to balance insight with minimal exposure.
What should I wear and do to prepare for my bone density test at Baptist Health?
Wear clothing without metal fasteners, zippers, or belts, and avoid calcium supplements for about 24 hours before the exam. Arrive a few minutes early so the technologist can review your history and answer any last minute questions.
How long does the scan take and will it hurt?
The actual scanning portion takes roughly 10 to 20 minutes, and the exam is painless. You simply lie still on the table while the imaging arm passes over your body without making contact.
Will I get immediate results or need a follow up appointment to discuss them?
A preliminary report may be available soon after the test, but the final interpretation by a radiologist is typically ready in one to two business days. Your referring provider will schedule a follow up to review the results and next steps.
