what is bone density
2 Apr 07
A bone density test uses special X-rays to measure how many grams of calcium and other bone minerals collectively known as bone mineral content are packed into a segment of bone. The higher your mineral content, the denser your bones are. And the denser your bones, the stronger they are and the less likely they are to break. Doctors use a bone density test to determine if you have, or are at risk of, osteoporosis.
