2025-12-29 – Weekly Medical Equipment News : Why is MRI so noisy?

Last week, our community delved into various crucial discussions around medical equipment management and optimization. Members focused on the practical challenges of maintaining privacy while capturing usability data, alongside spirited debates on improving device trial data integrity. There was also significant interest in cost-cutting measures in equipment rental and the technical reasons behind the noise levels of MRI machines.

Ask rental vendors for ‘silent’ gradient protocols and dual hearing protection; basics here: https://mriquestions.com/what-makes-noise.html Anyone seeing measurable comfort gains?

Quick example: we cut perceived MRI noise a bit by adding a thin viscoelastic pad under the headrest and head coil cradle — about 6 mm Sorbothane — so less vibration couples into the table; our sound meter at the ear showed about 2–3 dB drop and fewer startle motions. It’s a cheap, non-invasive tweak that fits the “cost-cutting measures in equipment rental” theme and doesn’t require protocol changes, though you’ll want to clear it with your safety team. Anyone else tried damping at the head/coil interface instead of just ear protection?

On our 3T, we trimmed perceived clatter by enabling the vendor’s “soft gradient ramps” on DWI and FSE, which added about 15% scan time but patients said it felt calmer. @jennyb_27, have you tried that alongside proper foam+earmuff fit checks? Small caveat: we only toggle it for anxious patients or pediatrics because of the throughput hit.

We shaved about 2–3 dB by tightening gantry cover fasteners and slipping thin neoprene washers under a few panel mounts — less sympathetic buzz on EPI; just check your service contract before touching hardware. @m_perry22 ever do a quick “rattle run” (loud sequence, walk-around to spot loose panels)? Like hunting the coin in a dryer, but patients said it “sounds less harsh.”.
