Magnetic resonance imaging (MRI) is based on the interactions between a static magnetic field generated by the scanner and the tiny fields that arise from individual atomic nuclei.

MRI produces particularly good images of soft tissue and provides greater contrast between different types of tissue than other imaging modalities.

There are numerous safety concerns associated with the MRI environment.

Many patients require general anaesthesia or sedation for MRI because of the need to minimize movement during potentially long scanning times and the noisy and claustrophobic environment of the scanner.
