Frequently Asked Questions

  • What is an MRI?

    Magnetic resonance imaging (MRI) is a technique that uses magnetic fields and radio waves to create sectional images of your body. It is a special form of layer examination, which, in contrast to computer tomography, does not use X-rays. Soft tissue, such as brain, musculature and internal organs, and vessels are particularly well represented in the image.

  • How does an MRI scan work?

    An MR scanner consists of an annular magnetic tunnel, a radio transmitter and receiver placed around the examined body region, and a storage table on which the patient is driven through the magnetic tunnel. The examination is controlled at an operator station outside the MRI room. The obtained slice images are displayed on the monitor and can be exposed to films similar to CT or X-ray images.

    Since magnetic fields and radio waves are used with this procedure, you as a patient must discard all metal objects such as keys or magnetic-sensitive items such as credit cards or hearing aids.

  • What is a CT?

    Computed tomography (CT) is a special form of X-ray examination in which the part of the body to be examined is displayed “layer by layer”.

    Through the so-called fenestration, different types of tissue (for example, lungs, bones, soft tissues) can be displayed in great detail. Using mathematical methods, arbitrary sections and three-dimensional images can be calculated. A particular advantage of CT is the short examination times even in large examination areas.

  • How does a CT scan work?

    A CT scanner consists of a short ring tunnel (gantry) in which a system of X-ray generator and detectors rotates around your body and creates cross-sectional images. The examination is controlled at an operator station outside the CT room. The collected information is converted in a computer into individual sectional images and can be displayed on the monitor and exposed to films similar to X-rays.

    During the shooting you lie on a storage table, which is driven through the gantry opening. You may be given a contrast agent that makes certain structures of your body more visible. The actual measuring time is only a few seconds.

  • When is a contrast agent needed?

    Before some examinations by MRI or CT, e.g. Examinations of the brain, cervical soft tissue, vessels, thoracic and abdominal areas may be suspected. administered a contrast agent. This measure contributes to the improvement of the test results; The doctor can judge the pictures easier and better. Most people tolerate the contrast agent easily and feel only a quick temporary feeling of warmth.

    If contrast media are given during an MRI scan, good kidney function should be taken into account. This will be clarified during a medical consultation. In case of doubt, we perform a quick test of kidney function in advance.

    Since the contrast agent given in CT examinations contains iodine, which causes allergic reactions in some people, talk to your doctor first about any allergies that may be present.

  • Why are whole body check-ups more expensive than other check-ups, e.g. those at the family doctor?

    Modern radiology works with devices that are very expensive to buy and to maintain. And at a radprax full-body check-up, your entire body is examined using magnetic resonance imaging (MRI). This is very time consuming. But MRI allows to study almost all organ systems with very high accuracy.

    And some changes are detected “from the outside” or with an ultrasound examination only at a later time, while you can present with modern MRI pathological changes at a very early stage.

  • Are the radiological examinations at the check-ups not harmful to me?

    With our full body check-ups i.d.R. No X-rays used. We work with magnetic resonance imaging (MRI), which generates high-resolution images through the use of magnetic fields and radio waves. Only in the case of a corresponding individual medical indication are additional methods used to clarify a finding, which can then also receive X-rays.

  • Can not it be that the check-ups found something that would not cause any problems and then burden me afterwards?

    Checkups provide clarity about the current state of health. Most of our clients, who come for a pure provision and feel healthy, are fortunately sent home with the knowledge that everything is healthy in their “green” area.

    Very rarely we notice a pathological change. Precisely then, targeted measures can often prevent the onset of a disease.
