Magnetic resonance imaging (MRI)

The MRI takes advantage of the fact that almost two thirds of the human body is made up of water. In a magnetic field, the hydrogen atoms always align themselves in the direction of the magnetic field and subsequently release electromagnetic waves themselves, which can then be measured. The MRI is a completely painless examination method.

Magnetic resonance tomography is an X-ray-free, gentle and fast diagnostic method that enables precise information about clinical pictures and is also of great importance in preventive medicine.

Information about our MR system

Canon's MR systems are the only ones in the industry that cover all aspects of patient care. Innovative technologies ensure diagnostic accuracy. The extremely short tunnel of the system, the feet-first imaging and the extremely quiet examination process, thanks to their patented Pianissimo technology, ensure improved patient comfort. A number of contrast-free angiography techniques make examination easier and improve patient safety.


What is an MRI scan?

With magnetic resonance imaging, the body is examined without X-rays. During the examination, short-lasting radio waves are generated by strong magnetic fields. The signals which are received from the body are evaluated with a computer. Magnetic resonance imaging is a very reliable and accurate method. If performed properly, the examination is completely painless and no harmful effects are currently known.

When is an MRI scan done?

Magnetic resonance imaging (MRI) is indispensable for many diagnostic questions, for example to find out whether back pain is caused by an inflammation or a herniated disc.

The MRI is particularly suitable for examining soft tissue - for example, connective-, muscle- or nerve tissue, the brain and other organs.

We can also display and examine fluid-filled cavities such as the heart, blood vessels, bile duct and pancreatic ducts very well with the MRI.

How long does the examination take?

The examination takes a few minutes to an hour, depending on the organ examined.

Does the exam cause pain?

The examination is completely painless and no harmful effects are currently known.

What must be considered during the examination?

Hearing aids, watches, jewelry, hair clips, glasses, etc. may not be taken into the examination room as they can become defective and/or cause image disturbances. Mascara must not/should not be worn during the examination. Patients with pacemakers, metal implants or an artificial heart valve must inform the doctor of this, before the examination. Essential additional information: Credit cards are erased by the magnetic field!

Does a contrast agent have to be administered?

Depending on the type of examination, intravenous administration of an MR contrast medium may be necessary, which can contribute to the representation of certain organs and anatomical body structures and thus helps to recognize pathological changes, which increases the informative value of the examination and confirms the diagnosis. Thanks to the latest technology, the required amount of contrast agent can be significantly reduced. Please note our contrast agent information sheets.
