Bone Densitometry (DEXA)

Bone Densitometry Dexa 1

What is a Dexa scan?

Bone Densitometry, also known as dual-energy X-ray absorptiometry (DXA or DEXA), is a non-invasive medical imaging technique used to measure bone density and assess bone health. 

This procedure involves minimal radiation exposure and is commonly employed to diagnose osteoporosis and evaluate the risk of fractures. It provides precise information about bone mineral content, helping healthcare professionals make informed decisions regarding bone health interventions and treatments. 

Bone Densitometry is an essential tool for early detection and management of osteoporosis, promoting overall skeletal well-being.

What happens during a DEXA scan?

Before you begin your DEXA scan you will have your height and weight measured. These values are considered when your bone density results are determined.

During the scan you will be asked to lie down on the DEXA table and a cushion will be placed underneath your knees during the lumbar spine portion of the scan. After that an object used to rotate your ankle and hip will be placed between your feet for the hip portion of the scan.

Sometimes your left forearm will also be scanned as well depending on the clinical indications.

How should I prepare for a DEXA scan?

There is no specific preparation for a DEXA scan, however it is best to wear comfortable loose fitted clothing for the procedure.

How long does a DEXA scan take?

A DEXA scan should take between 10-15 minutes in most instances.
