Bone Densitometry
This is a method to measure the density of your bones to estimate the strength of bones and the likelihood of bone fractures with only minimal or no trauma. If the bone density is very low, the condition is called osteoporosis and causes a very high risk of fracturing the bones. The "gold standard" method is called "Dual Energy X-ray Absorptiometry" - DEXA. This uses a very weak form of X-ray to scan your bones and uses a computer to convert this information to numbers.
Preparation: No preparation is needed. Do not take the calcium pill on the day of the exam. We need previous bone density data, if any, to compare.

Indications for bone density measurement
All women aged 65 and older.
Postmenopausal women under age 65 who have risk factors for osteoporosis such as family hitory, personal history of fractures and weight less than 127 pounds.
All men aged 70 and older. Anyone with fragility fractures.
Women considering therapy for osteoporosis, if BMD will help in the decision.
Women who have been on hormone replacement therapy for prolonged periods.Anyone with a condition or medication associated with osteoporosis.
Individuals recieving glucocorticoid therapy.
Individuals with hyperparathyroidism.
When determined to be medically necessary by a physician.
