# SF-004 — Slower MRI entry and vestibular responses

Why this matters
This retrieval lead asks a practical question: whether entering a strong MRI magnet more slowly reduces dizziness and involuntary eye movements. Those eye movements are called nystagmus. Full methods and results need review before any clinical recommendation, but the proposed link between movement and symptoms is directly testable.

Topic: Intermediate and static fields

Verification Group: Retrieval lead

Record Role: Retrieval lead

Featured: False

Exposure: Tesla-scale MRI static magnetic fields and motion through gradients.

Design: Human experiment.

Finding: Affirmative vestibular or neurobehavioural finding described in discovery dossier.

Boundary: Retained in a separate regime-specific catalogue. No inference to Wi-Fi or mobile-phone exposures.

Protection Question: Could entry speed influence dizziness and involuntary eye movements near a strong MRI magnet? The lead raises a practical question, but its unreviewed original results do not yet support a clinical recommendation.
