The computed tomography is an excellent imaging technique which uses x-rays to produce high resolution images of all body regions, all organs, blood vessels and lymphatic system as well as the entire musculoskeletal system.
Thanks to the high-tech equipment and multi-slice technology, the coronary arteries can be displayed without any interventional catheters and the large intestine without endoscope. All investigations are carried out in seconds. With our special CT device, the radiation load can be reduced by 70% compared to conventional devices (ultra-low-dose technology).
In the Radiology Ottobrunnt, all regular CT studies, from head to toe are performed. Except for examinations of the bones, usually all studies are carried out using intravenous, well tolerated contrast media (administered via the elbow vein).
Our extended choice of examinations includes
- Heart check up with calcium score and virtual angiography of the coronary arteries (cardiac screening)
- Smoker check up (lung screening)
- virtual colonoscopy (colon screening)
A CT examination can be carried out on carriers of pacemakers or other electronic implants as well as implanted prostheses or other metals.
Claustrophobia does not occur in CT examination.
A unit of X-ray tube and detector revolves around the longitudinal axis of the patient. The X-rays are attenuated on their way through the examined body region. The detectors measure the incoming x-ray photons that produce electrical signals and a computer converts the obtained information into multi-dimensional, overlay-free and high-resolution images.
The CT-Scanner is an approx. 60 cm deep gantry with a large opening and a movable CT-table.
Here you can gain an impression about the different radiation exposures in everyday life and in medical diagnostics.

Up to 70% reduction of radiation exposure by using low-dose and ultra-low dose techniques.
Exept in a life threatening situation CT examinations are contraindicated during pregnancy.
