And the denser your bones, the stronger they generally are and the less likely they are to break. Other terms used for bone density are bone mineral density (BMD) and bone mass. You can take steps right now, such as monitoring your calcium and vitamin D levels and utilizing weight-bearing exercises, to prevent or fight osteoporosis. The relative contribution of bone density to bone mechanical competence was largely species-dependent. A T-score for bone density reflects how much your bone density is higher or lower than that of a healthy, 30-year-old adult. Dwarf Mr Snow, Fred's Tie Dye, Saucy Mary, Sweet Scarlet, Kangaroo Paw Green, Idaho Gem and Banana Toes are just a few of the varieties one gardener is growing in a 4x8 bed of "bulletproof" tomatoes. However, as older adults tend to have low bone density, people with normal Z-scores could have osteoporosis. Actual size, fighting ability, aggression, ect, are more important. Other bone density tests emit less or no radiation at all: a QCT scan, NTx urine test, or vitamin D test. For various reasons, the DEXA scan is considered the "gold standard" or most accurate test.
