One forgotten key in a trouser pocket, and the magnet pulls it across the room. The scan stops, the schedule slips, and somebody has to explain what went wrong. A growing number of radiology teams are fixing this at the source with smart lockers placed at the MRI suite entrance. This article covers what those lockers have to do, how they cut scan delays, and what to check before you buy. Why metal and an MRI field do not mix An MRI scanner runs a strong static magnetic field that stays on even when the machine is idle. Ferromagnetic items — phones, keys, coins, watches, hairpins, tools, bank cards with magnetic strips — react to that field. In the scan room they become projectiles; outside it they can be wiped or corrupted.
