BONE DENSITY TESTING (DEXA SCANS)
What is Bone Density testing?
Bone Densitometry, also called DEXA, or Dual Energy X-ray Absorptiometry is a simple, painless scan that measures bone mass to determine if a person is at risk of having a broken bone because of osteopenia or osteoporosis (weak or porous bones). Bone Density testing allows you & your doctor to take steps to prevent you from getting a fracture if you are at risk. Most Bone Density testing is done by scanning the spine & hip since these are the bones that usually break because of osteoporosis.
Are there different kinds of Bone Density Tests?
Yes. There are “peripheral” scans (of the heel & wrist,) and there are “central” scans (of the hip & spine). Although the peripheral scans are helpful for screening, they are not as precise or accurate as the central tests, and can sometimes miss the presence of Osteopenia or Osteoporosis. Central tests are so accurate, they can detect a bone density change of as little as 1%.
