DEXA Bone Densitometry
DEXA (which stands for dual energy x-ray absorptiometry) scanning uses X-rays in very small doses to measure the density of your bones. The density of your bones will show how strong they are. Your exposure to x-rays is very low and is similar to what you would receive on a long distance plane flight.
What to expect?
It is most convenient if you wear loose clothing with no metal domes or other attachments from chest to knee. A tracksuit is ideal.
You will lie very still on a padded table for 5-10 minutes while the arm of the machine passes over the lower spine and hip. You will feel nothing.
