why don't they have metal detectors on the doors leading to the MRI?
My guess? They're not sensitive enough for small bits, but could still lead to staff complacency.
i think small bits like tattoos are just painful, but there should be one for the bigger items that always ends up in the news, like the guy who brought in a gun
Possibly because a standard magnetometer cannot detect reactive elements down to the level that would be affected by a giant insane field associated with an MRI?
A simple xray, or a pass-through of a single metal detector at a court house is one thing….
…but Imagine a tattoo with ferrous ink. In a simple airport magnetometer, it’s no thing. In an MRI it’s ripped out of flesh.
Basically tattooing itself can be a very wild scenario. I caught artists in Tunisia making do and had a friend shooting cats in Cuba as we provided ink.
Because medical drama shows need the unexpected surprise moment
That's an excellent question. I guess they never thought of it?
