Dual-Energy Absorptiometry (DEXA)
Bone Densitometry is an X-Ray scan, it's commonly known as a Bone Mineral Density (BMD) Scan or DEXA Scan (Dual Energy X-Ray Absorptiometry). A DEXA Scan measures the density (thickness) of your bones, the higher the density, the stronger the bone is.
Diagnosis of Osteoporosis or severity of bone loss can be determined and whether or not the patient is responding to treatment.
A DEXA Scan is the most accurate test for diagnosing Osteoporosis, or “porous bones". Osteoporosis is a disease where the bones lose density which can lead to fractures, pain, and deformities. You may not even notice you have it until you receive a painful fracture, so early detection is important.
