I’ve never had an MRI or CAT and haven’t had any but dental X-Rays in 20 years. So MRI tech is relatively unknown to me.

I knew an MRI was dangerous in the presence of ferrous materials, but that’s about it...

If they have metal detecting equipment, then they should use it and just eat the false alerts, what’s the use of having security equipment if you ignore it?

The issue is one of complacency. When it goes off for every patient, soon people, even those that know better, tend to ignore the warning. We have also noticed that, over time, people tend to depend on the detectors for screening and the investigation and questioning process becomes a sometimes thing.

We have found that a much better process is to require a standardized questionnaire, consistent questioning, and if in doubt, investigation of specific types of implants to determine MRI compatibility. If there is ANY doubt whatsoever, that patient gets another type of study.
