How are radiographs made?
Taking a radiograph is very similar to taking a photo, except we use x-rays instead of light rays. Different tissues in the body absorb x-rays to differing degrees. Of all the tissues in the body, bone absorbs the most x-rays. This is the reason that bone appears white on a radiograph. Soft tissues, such as the heart, kidneys or other organs, absorb some but not all of the x-rays, so they appear on a radiograph in different shades of grey. The air-filled lungs absorb relatively few x-rays so appear dark grey or black on a radiograph. We will demonstrate and explain the radiographs when your pet goes home.
