Computed tomography
Generating tomograms of the inside of the body with computed tomography has now become the medical standard. This is an established and fast method, and it is no longer possible to imagine cross-sectional diagnostic imaging without it.
More details on

computed tomography

Since the 1970s, computed tomography has been one of the most reliable diagnostic methods. The attenuation of the X-rays as they pass through the body is measured with detectors and converted into cross-sectional images using a computer. These continuous images enable precise evaluation and analysis, since the finest structures can be imaged.
Our examination equipment
    It is very important to us that our institutes are equipped with the latest technology. For this reason, we have the very newest machines in our examination rooms. In computed tomography, we work with a scan rate of 2 to 350 milliseconds with simultaneous acquisition of up to 384 "slices". This provides us with precise, continuous images, which show even the smallest differences in density, for example in the lungs or the abdomen. Even the imaging of the teeth or the determination of the bone mineral content for osteoporosis examinations is possible with special measuring programs.
    We are particularly proud of our dual-source, dual-energy CT scanner, which has the worldwide serial number 14. It contains two X-ray tubes – the result: double scan rate, higher image quality, better imaging, even more precise diagnostics and a lower radiation dose of up to 90 per cent.
Frequent applications
  • diagnosis of changes in the brain
  • examination of diseases of the spinal column (e.g. intervertebral discs)
  • diagnosis of diseases of the viscerocranium (e.g. paranasal sinuses) and the neck (e.g. larynx or lymph nodes)
  • method to examine the fine structure of the lungs, the bones and the middle and inner ear
  • evaluation of diseases of the thorax and the lungs
  • examination of diseases of the abdominal organs (liver, pancreas, spleen, kidneys and adrenal glands)
  • special examinations of the small intestine and the colon for treatment-resistant and unclear abdominal pain and chronic inflammatory bowel diseases
  • the ideal method to image lymph nodes
  • diagnosis of diseases of the pelvic organs (e.g. ovaries) and the pelvic soft tissues
  • a safe method to image the large vessels (e.g. aorta or pulmonary arteries)
  • dental CT: three-dimensional imaging of the upper and lower jaw and the teeth (e.g. before dental implants)
  • osteoporosis CT: reliable and conclusive method to determine bone density
  • cardio CT: the most reliable, non-invasive method to determine the calcium content of the coronary arteries and to rule out or provide evidence of a significant coronary heart disease
  • virtual colonoscopy: four-dimensional imaging of the colon and the rectum to detect or rule out the presence of polyps and tumours (alternative diagnostic method to conventional endoscopy)
  • low-dose multi-slice spiral CT of the lungs: currently the best method for early detection of bronchial carcinomas at the same exposure to radiation as in a thorax X-ray
  • virtual angioscopy: three-dimensional imaging of the inner structure of the vessels
  • virtual tracheobronchoscopy: four-dimensional imaging of the trachea and the bronchi to rule out or provide evidence of and for the surgical planning of bronchial tumours
  • CT-targeted pain therapy: injection of medicines exact to the millimetre into the anatomical structures responsible for the pain, primarily the cervical spine, the lumbar spine and the sacroiliac joint
  • CT-targeted organ biopsies: minimally invasive tissue extraction (e.g. from the lungs or the liver) for an exact histological characterisation
Frequently asked question
The examination takes a maximum of ten minutes. In the CT room, you lie on an examination bed, which moves quickly through the opening of the CT scanner during the examination. An X-ray tube rotates around your body. The attenuation of the X-rays as they pass through the body is measured with detectors and converted into cross-sectional images using a computer.
It is important that you keep still during the examination, avoid any movements and follow the breathing commands exactly. To achieve good results, it is important to hold your breath briefly in many examinations. You will be under the supervision of expert staff throughout the entire treatment.
Computed tomography is a harmless form of examination and completely painless. The necessary radiation dose can be reduced by up to 90 per cent using the latest technology, and the examination times are becoming increasingly shorter.
Depending on the type of examination, the administration of an intravenous, non-ionic, iodine-containing X-ray contrast medium may be necessary. It can contribute to the imaging of certain organs and anatomical bodily structures and help to detect pathological changes. The contrast medium increases the relevance of the examination and ensures diagnosis. Thanks to the latest technology, it is possible for us to significantly reduce the quantity of the contrast medium administered. Please take note of our contrast medium information sheets.
It is important that you bring your kidney laboratory values and your thyroid values to the examination.
