Siemens turned MRI noise into a children's audiobook to calm kids

An MRI scanner works by cycling powerful magnetic gradients that produce loud, jarring mechanical noise — banging, whirring, clanking — for the many minutes a scan takes, and the patient has to lie completely still inside a narrow tube the whole time or the images come out unusable. For a frightened child, that combination routinely fails: motion means a repeated scan or a cancelled one, and hospitals default to sedating or even fully anesthetizing young patients to get a clean image, which adds cost, recovery time and its own clinical risk to what is otherwise a routine diagnostic procedure.

The standard mitigations hospitals already use — child-friendly decorated scanner rooms, noise-cancelling headphones, a parent talking the child through it, cartoons playing beforehand — all treat the machine's noise as something to hide from the child or distract them away from. None of them change what the child actually hears the moment the scan starts, which is still the same frightening banging it was trying to avoid.

Wove the MRI's predictable clunks into audiobooks as plot sound effects, so real noise became story beats the child listened for instead of a threat.

The MRI's noise is a fixed sequence per scan type, so it can be scored in advance like music.

Children hear the same sounds they feared, but now as story elements, so their sensory experience confirms the story.

Because the story and the noise are the same event, following the story aligns with holding still for the scan.

This reduces the gap between expectation and reality that undermines distraction-based approaches.

When an unpleasant stimulus is mechanically predictable, reframe it as a narrative element synced in real time, rather than masking or distracting.

The program launched as a pilot across Portugal's CUF private hospital network, where radiology staff reported a marked drop in child anxiety during scans and reduced need to fall back on sedation — Siemens has not published a peer-reviewed clinical figure for the reduction as of this writing, but the pilot's reception was strong enough that the company moved to expand Magnetic Stories into Spain, Germany, Italy and the UK, with plans for real-time AI-generated narration that can sync to any hospital's specific scan sequence.
