Magnetic resonance imaging (MRI)

Radiation-free examination for comprehensive diagnostics


Magnetic resonance imaging, also known as nuclear spin tomography, is a radiation-free examination procedure in which images of various parts of the body are generated using an electromagnet and radio waves. The body is not exposed to any radiation in the process. For this reason, magnetic resonance imaging is completely safe for use during pregnancy (from the second trimester onwards) and for children.

Our state-of-the-art equipment, which includes three semi-open Siemens Aera MRI machines (1.5T), one Siemens Skyra MRI (3T) and one Philips Ingenia MRI (1.5T), accommodates patients with claustrophobia. In the case of most of the body parts being examined, the head can remain outside the cylinder.

Magnetic resonance imaging procedure (MRI scan)

All metal objects such as jewellery, wristwatches or hearing aids must be removed prior to the examination. Metal objects located inside the body, such as prosthetic joints, metal plates or fixed dentures, do not generally cause any problems.

Before the start of the MRI scan, please specify if any metallic objects such as:

  • stent grafts (e.g. stents),
  • vessel clips,
  • an artificial heart valve,
  • an insulin pump,
  • metal fragments,
  • or tattoos,

are present. These can disturb the magnetic field and lead to significant injuries.
Patients with pacemakers or inner-ear prostheses (cochlear implants) are disqualified from the scan.

You will slowly be moved into the scanner on a flat bed. How far you will be moved into the opening depends entirely on the region of the body being examined.

During the scan you will be provided with ear muffs/noise-protection headphones. Alternatively, music can gladly be provided.

For certain examination procedures it may be necessary to inject a contrast medium into one of your veins before the magnetic resonance imaging. This will be flushed out of the body after a short time.

Patients with diseases of the kidney, diabetes or hypertension must provide a current creatinine level before the start of the scan.

Should you have further questions, you can find more information available on our Services page.

“I have MRI claustrophobia!” - What to do?


MRI claustrophobia: No problem thanks to modern technology

Many patients suffer from MRI claustrophobia. Patients who struggle with claustrophobia in confined spaces now have no need to worry: At Diagnostik München we offer 1.5 Tesla MRI equipment with particularly generous openings.

No chance of MRI claustrophobia

Our new MRI equipment possesses a 70cm-wide and 1.3 metre-long cylinder. This allows MRI scans to be carried out feet-first. This means that patients with claustrophobia have total freedom of movement in the head region. In addition, music can be provided on demand using headphones. Various lighting effects also contribute to a sense of comfort.

Needless to say, this freedom of movement has no effect on the accuracy of the MRI scan. Even the tiniest changes can be shown thanks to the outstanding image quality.
