What are the methods of measuring bone density?

DEXA scan, spine&hip: Primary care doctors usually measure bone density with a DEXA (dxa) scan, which is an x-ray study that takes measurements from a person's spine and femur (hip bone). Calculations and results are sent to the doctor. A patient returns to his or her doctor to discuss the meaning of the results which depend on gender, age, body type (big-boned vs. Petite), other medical conditions, medications, etc...

DXA: They employ a dual-energy absorptiometry, or DXA also referred to as DEXA scan using very little radiation. You get a ty score and the lower your score, the weaker your bones are and the risk for fracture is greater.
