Patient information Computed tomography (CT)

How does the technology work?

Computer tomography (CT) is an imaging technology capable of creating three-dimensional pictures of the body using X-rays. An X-ray tube rotating around your body creates a number of fine cross sections of your body simultaneously.  Using a modern 3D processing method, these cross-sections are combined to create highly detailed, and extremely precise three-dimensional images of your organs, bones and blood vessels.

When does it make sense to use CT?

We employ CT technology both for diagnostic tasks (particularly for complaints relating to the head, neck, chest cavity, abdomen, skeleton and blood vessels) as well as in CT-controlled minimally invasive pain therapy of the spinal cord. In this procedure, medicines are injected directly onto nerve roots (a treatment known as periradicular therapy) or into vertebral facet joints (referred to as facet joint injection), in a process guided CT-created images.  Carrying out this therapy under CT control yields the greatest possible therapeutic success while also posing the lowest possible risk for the patient.

What happens in a CT examination session?

The time required for the CT examination itself is between 30 seconds and 3 minutes. If the examination is being conducted on organs in the abdominal area, the patient will first need to ingest a highly dilute contrast medium over a period of between about 45 and 90 minutes. This contrast medium fills out the patient’s tube-shaped organs (i.e. the stomach and small and large intestine), thereby significantly improving the diagnostic power of the radiological technique for such organs.
