Dual-energy X-ray absorptiometry (DXA) is a non-invasive and painless test used to measure bone mineral density and determine bone health. DXA uses low-dose X-rays and is usually performed on the lower spine and hips.
CRA Medical Imaging classifies bone health using the World Health Organization's category for bone mineral density.
Patients should refrain from calcium supplements 24 hours prior to the examination.
