Bone Mineral Density Test: Normal and Osteoporosis


Bone mineral density of spine

Courtesy of Intermountain Medical Imaging, Boise, Idaho.

Figure 1 shows a bone mineral density (BMD) test of a healthy older woman. The X-ray shows a healthy spine. The BMD is determined by the X-ray. The graph shows the bone mineral density number in the green zone (normal). Figure 2 shows a BMD test of an older woman with osteoporosis. The X-ray shows weaker bones. The graph shows the bone mineral density number in the red zone (osteoporosis), placing her at much greater risk for broken bones (fractures).
