In computed tomography (CT), many X-ray images of an object are taken from different directions; so-called “sectional images” are subsequently reconstructed from the acquired volume on the basis of these images. Computed tomography is used only with exact attention to radiation protection and when the examination is clinically necessary.

Sometimes the use of contrast medium (iodine) is required for differentiation between individual structures and between healthy and diseased tissue. Adverse side effects occur (extremely) rarely.
