Bone Densitometry

Bone density scanning, also called DEXA (dual-energy x-ray absorptimetry), is an enhanced form of x-ray technology that is used to measure bone loss.  DEXA is today's established standard for measuring bone mineral density (BMD).  This test is for men and women.  It is estimated that 1 in 3 women and 1 in 12 men over the age of 50 worldwide have osteoporosis.  It is responsible for millions of fractures annually mostly involving the lumbar vertebrae, hip, and wrist.  Fragility fractures of the ribs are also common in men.

A Bone Densitometry Scanner is used to detect osteoporosis.  Rock Creek Imaging has state-of-the-art densitometry equipment that is operated by registered radiologic technologists.  A bone density scan takes approximately 15 to 20 minutes to complete.  A routine scan is done of the spine and hip. It is a painless test that requires little to no advanced preparation.

Osteoporosis Osteoporosis is a crippling disease which is growing in numbers each year.  It is known as the "silent stalker" because there may be no symptoms until a fracture occurs and a diagnosis is then made.  The word osteoporosis means "porous bones".  This disease causes bones to weaken by the loss of minerals, especially calcium.

Osteoporosis is treatable and preventable.  Early diagnosis, therapeutic intervention, and the use of bone density testing greatly improves the prognosis for patients. Risk Factors for Osteoporosis Certain factors are more likely to develop osteoporosis.  In women, the cessation of estrogen production at menopause induces an acceleration of bone loss.  Excessive loss in men is often linked to disease or certain medications.  There are a number of risk factors that can lead to osteoporosis.  Here are a few: Women over the age of 50 Men over the age of 55 Tobacco usage Excessive caffeine intake Lack of exercise Low intake of calcium Chronic back pain Family History Hormone Therapy   DEXA Image: Spine
