Sectional images of the body are created using magnetic and high frequency fields. There is therefore no exposure to radiation during the examination. Other advantages include better differentiation between soft tissue structures, and the arbitrary selection of layer directions.
In our centre, 4 state-of-the-art MRI devices, with different field strengths, are available (3 tesla: Siemens Magnetom Skyra, 1.5 tesla: Siemens Magnetom Aera and Magnetom Espree. General Electric Signa).
In most cases, the investigation time (time within the device) is about 20 minutes. However, for complex issues, the investigation may take up to 45 minutes, or even longer.
The results of the examination will be discussed with you once the images have been processed. You will also receive the images immediately. The written report is sent to your referring doctor by fax – usually on the same day.
The most important areas of application of MRI are:
In the Examination preparation section, you will find information on how to prepare.
So-called semi-open MRI scanners are available both in our centre, and in our branch in Gräfelfing, in the form of Espree and Aera devices. In contrast to conventional MRI devices, these have a significantly wider tunnel, which offers comfort similar to that of a CT scanner, and a shorter design. Unlike so-called open MRI devices which only have a field strength of between 0.2 and 1 tesla, the semi-open devices have a field strength of 1.5 tesla. Therefore, even the most sophisticated high-resolution investigations are possible in a semi-open MRI scanner.
Comfort during the examination is therefore greater than with other devices.
The device is particularly advantageous for obese patients, as well as patients with claustrophobia or reduced mobility.
In many cases (e.g. during knee and ankle examinations), it is possible to position the head outside the device. The head is always near to the opening of the device during pelvic or spinal examinations.
For examinations of the head, the cervical spine (CS) or the shoulders, for which the head needs to be positioned inside the MRI scanner, there is an open space of approx. 30 cm above the face. In the case of serious claustrophobia, the examination can be carried out with sedation or in a CT scanner, after prior consultation.
When making an appointment by telephone, please feel free to inform us of your specific needs, and we will discuss the best examination possibilities for you.
