Bone Densitometry
DEXA – Bone Density Testing
DEXA scanning has become the most widely used method for measuring bone mineral density for several reasons. When compared with plain X-rays, DEXA scanning more precisely documents small changes in bone mass and is also more flexible since it can be used to examine both the spine and the extremities. DEXA scanning is less expensive, exposes the patient to minimal radiation and is more sensitive and accurate at measuring subtle changes in bone density over time or in response to drug therapy.
About the Procedure
A Bone Density study is the most common procedure used to measure bone mineral density and is the only method that can make a definitive diagnosis of osteoporosis and monitor a patient’s response to treatment.
Preparation
The test is performed by a technologist and requires no injections, sedation, special diet or any other advance preparation. (If you take a calcium supplement, please refrain from taking it 24 hours prior to the exam.) Inform the technologists if you might be pregnant.
During the Procedure
You will lay fully clothed (no metallic zippers or belts) on a padded table while the DEXA scanner beams x-ray energy from two different sources towards the bone being examined (usually the lower spine or hip). When examining the spine, your legs are supported on a padded box to flatten the pelvis and lower the spine. To assess bone mineral density in the hip, your foot is placed in a brace that rotates the hip inward, and the scanning procedure is repeated.
A computer is then used to analyze the resulting images and calculate bone density based on the amount of radiation absorbed by the bone.
The procedure can take up to 30 minutes.
After the Procedure
You may resume normal activities.
Follow-up
A board certified Radiologist from CRL Imaging will interpret the scan and relate a written report of the information to your referring physician within 24 hours. Anything needing immediate attention will be called to the referring physician the day of the exam.
