Spiral Computed Tomography (CT)

Modern spiral computed tomography (CT) is based on an X-ray examination in which an X-ray tube positioned across from a detector system rotates around the patient while the patient moves through the opening (gantry) of the computer tomography device. The density differences caused by the attenuation of the X-rays in the patient are being record in a spiral-shaped arrangement. The X-ray scanner produces cross-sectional images of the part of the body to be examined. For example, the location of a disease outbreak in its relationship to the various organs is represented in a clear fashion. This can be of great value for a conservative treatment (medication, physical), for planning surgery, and in some cases for radiation therapy.

In order to determine diagnostically conclusive differences in density, contrast agents will be administered for some examinations. For example, prior to an abdominal examination, the patient will drink a water-based contrast agent over the course of about 30 minutes to enable a good image of the stomach and the intestinal tract.

For many examinations, an intravenous contrast agent is necessary and will be administered automatically by an application through the arm vein. Since the contrast agent contains iodine, it should always be clarified whether an intravenous contrast agent is appropriate (allergic reactions, thyroid hyperthyroidism, medications, renal failure).

The examination takes place in a specially designed room. The patient lies on a bed, which slowly moves into the approximately 70 cm wide opening of the device. Modern computed tomography is a rapid diagnostic procedure and claustrophobia is not an issue, since the opening (gantry) of the CT provides adequate space. During the acoustically or visually displayed recording times, which take only a few seconds, the patient should be lying still and should not speak.
Computed tomography is not suitable for pregnant women. For children, the necessity of having a CT examination should be assessed with scrutiny. If you have any questions prior to a CT examination, please consult your physician.

In 2008, our spiral CT department was relocated, and the building was completely renovated. The computed tomography department is now located on the second floor along with the central registration area and with X-ray diagnostics, radiation therapy, and ultrasound.
