Magnetic resonance imaging (MRI) investigation

Magnetic resonance imaging (MRI) is a diagnostic imaging method that does not use ionising radiation for image acquisition. Because the most common atom in the body is hydrogen, the tomographic image is obtained from the behaviour, location, concentration of hydrogen atoms and chemical bonds with other atoms. The investigation is performed in a magnetic field that is thousands or tens of thousands of times stronger compared to the magnetic field of the Earth. While the patient is in the magnetic field, radio waves with a certain frequency are transmitted resulting in the excitement of atoms and signals, which are the basis for the reconstruction of an image.

Medicum provides MRI scans of the following regions of the body:

  • Brain
  • Vertebral column
  • Joints

Absolute contraindications:

  • Cardiac pacemaker
  • Brain aneurysm clips
  • Aortic clips
  • Implanted neuronal transmitters
  • Insulin pumps
  • Metal foreign bodies in the brain and eye region

Magnetic resonance imaging scans are performed in Lasnamäe Medicum (Punane 61, Tallinn).
