Dexa scan

A DEXA scan or Dual Energy X-ray Absortiometry scan is a diagnostic tool that measures bone mineral density. This type of scan is usually prescribed for those at increased risk of osteoporosis. p DEXA or peripheral DEXA is used to measure bones on the periphery of a person such as wrist, fingers and heels. Central DEXA is used to measure bones in the spine and hip. This type of DEXA scan can accurately measure low bone density and is the preferred test for diagnosing osteoporosis. An imager passes over your body, emits radiation from two different sources in alternation. The DEXA scan differs from the regular bone scan in that the use of 2 different x-ray energy sources provides precision and accuracy. Besides it is able to detect loss of bone density much earlier than when it can surface on a regular x-ray. A detector measures the amount of radiation that comes through the bone being examined. This throws light on its density. A Dexa scan usually takes about 20 minutes and involves small amount of radiation.
