Bone Densitrometry

Bone densitometry measures the amount of calcium contained in bones. Bone mineral density increases until between the age of 20 and 30, remains constant until the age of 40, then decreases gradually or even rapidly in women at menopause. Low bone density represents an increased risk of fracture and/ or vertebral compression. It uses a very small quantity of X-rays (the technician does not need to protect himself behind glass or a lead apron).
The measurement of the radiation after crossing the bone therefore gives information on its density. The measurements are taken at the level of the column and the hip, sometimes at the wrist.
