Also known as Dual energy X-ray Absorptiometry or DXA, bone densitometry is the technology used to measure and monitor changes in bone density. The gradual loss of density weakens the bones and leads to fractures. This condition is called osteoporosis. Many factors such as dietary habits and family history contribute to the development of this disease. A bone densitometer can let patients know whether or not they have osteoporosis or if they are at risk for developing the disease.
 
Patient Information
The patient is required to lie down on an examining table where a DXA source of two low-dose x-rays measure the bone density of the fracture prone area. This procedure is painless and relatively harmless. The bone densitometer accurately and quickly measures the patient's bone mineral density (BMD). This test also gives a comparison of the results against a reference population based on age, weight, sex, and ethnicity. The resulting information helps the physician determine the next steps with regard to prevention and treatment.
 
Before the Procedure
No preparation is required for the exam.
