Bone Densitometry / DEXA Scans

Bone densitometry, also known as a DEXA scan (Dual Energy X-ray Absorptiometry), is routinely used to accurately diagnosis osteoporosis, osteopenia, and to estimate bone fracture risk. These scans used ultra-low dose radiation to image the density of bone tissue.

Osteoporosis & Osteopenia

These conditions most often affect post-menopausal women due to the gradual loss of calcium and other structural changes within the bones. The loss of calcium and structural changes makes the bones thinner and weaker, increasing the likelihood of a fracture.

Fracture Risk Assessment

What is a Fracture Risk Assessment? This is an assessment of an increased risk of fractures attributed to a patient's age, body weight, family history of osteoporosis, any previous bone fractures, and if there is a history of smoking tobacco products and/or excessive alcohol consumption. 

What to Expect During a Bone Density / DEXA Scan

• This exam is completed by measuring the bone density in your spine or hips. For this exam you will need to lay on a padded table, an imaging detector will be above you and an x-ray tube under the table. The imaging detector will slowly pass over the body part being imaged while the x-ray tube below you produces low-dose radiation beams. 

• During the assessment of the bone density in your spine, your legs will be supported by a sponge or padded box to help flatten your spine and pelvis. 

• During the assessment of the bone density in your hips, your feet will be positioned and supported to help align your hip joints. 

Patients who may have additional diagnostic testing involving iodinated or barium contrast should schedule a DEXA scan prior to the other testing.

If a DEXA scan cannot be scheduled prior to the diagnostic testing prior, it is recommended to wait at least one week after the contrasted examination(s).
