What happens if you take calcium before a bone scan?

Does calcium absorb x-rays?

The absorption of X-rays by a tissue depends on the quality of the X-ray beam, the character of the atoms in the tissue being examined as well as the density and thickness of this tissue. The amount of X-ray absorption by the tissues defines the density of the shadow cast on the radiograph.
