Enabling Continuous Intracranial Pressure Monitoring During MRI: A Technical Note on the Development of an MR-Safe Support Frame.
Marcelo P Martins, Malin Ringholm, Jacob Engström and 1 others
PMID 41131929WHAT IT FOUND
A custom MR-safe support frame kept intracranial pressure monitoring and drainage connected during brain MRI.
It was used in more than 50 scans with no safety issues reported.
Key findings
01The frame placed the pressure transducer and external ventricular drain system just outside the MR bore, and the setup allowed continuous monitoring and an open drain during scanning.
02The frame was used in more than 50 MR scans with continuous intracranial pressure monitoring, and no safety issues were reported.
03All frame parts and accessories were non-metallic and arranged so no component touched the patient, to maintain MR safety.

What it does not show
This is a technical note, not a trial or cohort study, so it does not show that continuous monitoring during MRI improves patient outcomes. The only safety result is that no safety issues were reported in more than 50 scans; the note does not give patient numbers, scan details, adverse events or comparison data. The note does not report how many patients were scanned, what diagnoses they had, or whether pressure readings remained accurate during scans. The setup was developed for one hospital's monitor and MR table, and the bottom plate may need adjustment for other tables. The contact board was not labelled with MR safety information, and the authors applied the whole system's MR-conditional limits as a precaution. Claims about earlier MRI, less CT use and better detection of injury are future possibilities, not results.

The easy way to misread this
Do not read the absence of safety issues in more than 50 scans as proof that this frame improves patient outcomes. It is a technical note with no comparison group or clinical endpoints.
