What is a Bone Density Study?

 

The bone density test is used to determine bone mineral content and bone density.  This test helps to diagnose osteoporosis as early as possible.  The earlier osteoporosis is detected, the more effective the treatment and the milder the clinical course.  If osteoporosis is not detected until fractures occur, or thin bones are seen on plain film X-rays, the success of treatment is less likely.  The dual energy X-ray absorptiometry, or DEXA scan is the most common bone density exam used.  Before the test is performed there is no fasting or sedation required.  The patient will be asked to remove all metallic objects that may be in the scanning path.  During the procedure the patient lies on an imaging table.  There is a photon generator under the table that is continuously passed under the body.  A camera is passed over the patient parallel to the generator.  The image is then projected onto a computer screen.  The bone density test takes approximately 30-45 minutes and is pain free.  This test also uses only minimal radiation.  After the test the patient may resume regular activity.
