Why do only bones show up on x-rays?

Different parts of the body absorb the x-rays in varying degrees. Dense bone absorbs much of the radiation while soft tissue (muscle, fat, and organs) allow more of the x-rays to pass through them. As a result, bones appear white on the x-ray, soft tissue shows up in shades of gray, and air appears black.

What does not show up on an x-ray?

X-rays don’t show everything. Muscles and ropy fibres (ligaments) don’t show up in a useful way on an X-ray. And some problems, like a bleeding stomach ulcer, don’t show up on X-rays. If your X-ray doesn’t give a clear picture, you may need other tests.

You may have a contrast dye injected into your blood so the doctor can see your body structures more clearly on the CT scan.
