About DEXA (Bone Densitometry)
What is a DEXA scan?
Bone densitometry (DEXA bone scan) is used to measure your bone mineral density. It is a very simple, quick examination that involves taking images of your bone structure to help determine bone status and fracture risk.
Is the exam safe?
Bone densitometry involves an extremely small dose of radiation that delivers less than one-tenth the dosage of a chest x-ray.
How long does a DEXA bone scan take?
Spine or femur measurements take approximately two to five minutes, while total body measurements take approximately 10-15 minutes. Your clinician will determine the examination that is best for you.
What to Expect
The exam is simple, quick and painless. It requires you to lie still, breathe normally and relax while the bone densitometer does the work. No change of clothing is required; however, please avoid metal buttons or buckles.
- No calcium supplements or osteoporosis medication 24 hours prior to your exam.
- No barium, nuclear medicine or I.V. contrast exams within 7 days prior your exam.
- Please wear comfortable clothes and avoid metal buttons or buckles.
