Bone Densitometry

Bone densitometry, also known as dual-energy X-ray absorptiometry (DXA or DEXA) scan, is a diagnostic test used to measure bone mineral density (BMD).

Purpose:

Bone densitometry is primarily performed to assess the strength and density of bones, aiding in the diagnosis and monitoring of osteoporosis or other conditions that affect bone health.

Procedure:

During a bone densitometry scan, the patient lies on a padded table while a scanner arm passes over the body, emitting low-dose X-rays. The machine measures the amount of X-ray energy absorbed by the bones, which helps determine their density and strength.

Measurement sites:

Common areas assessed by bone densitometry include the spine, hip, and sometimes the forearm. These regions are most susceptible to fractures associated with osteoporosis.

DXA T-score:

The results of a bone densitometry scan are reported as T-scores, which compare the patient’s bone density to that of a healthy young adult population.

Importance of bone density testing:

Bone densitometry is a crucial tool for assessing fracture risk, guiding treatment decisions, and monitoring response to therapy in individuals at risk of osteoporosis or other bone-related conditions.

Preparation and safety:

Bone densitometry is a non-invasive and painless procedure that usually requires no special preparation. The amount of radiation exposure during a DXA scan is minimal, making it safe for most individuals.

Result:

The results of a bone densitometry scan should be discussed with a healthcare professional who can interpret the findings in the context of your medical history, overall health, and other risk factors for bone-related conditions. They can provide appropriate recommendations for treatment, lifestyle modifications, and monitoring.

At Harley Street Radiology Department, we are equipped with state-of-the-art imaging technology called Stratos DR –3D DXA (Dual-Energy X-ray Absorptiometry), an advanced imaging technology for assessing bone health.

3D-DXA is a breakthrough technology that uses routine BMD images to modelize a 3D image of the femur. Unlike traditional DXA scans, which provide 2D images, 3D DXA creates a three-dimensional representation of the bones, offering enhanced visualization and analysis. 3D-DXA provides automated workflow, retrospective analysis, patient follow-up and Report generation.
