  • The mechanism they are describing here is the emergency one (like if a human is trapped against the machine by something metal and is being crushed - you need to kill the magnet NOW). There is a slower, much safer mechanism for deactivating the magnet that should have been used here but that would require the officer admitting he had made a mistake and asking for help.

    Also I just want to point out that the rifle should be considered no longer safe to use unless thoroughly inspected by an expert. In a similar case some years back, the police officer’s sidearm was pulled into the machine. After retrieval it was found that the weapon had been magnetized by the scanner and as a result the firing pin was able to spontaneously release.


  • I’m biased but putting the onus on doctors here completely misses the point in my opinion. Let me just point out that this isn’t a “policy change” - these states have made it illegal to perform these procedures. In at least one state the physician can go to prison.

    In an idealistic worldview we can expect every person to do the morally optimal thing every time without regard to consequences but that simply isn’t realistic. You are basically advocating that physicians should be jumping to break the law and therefore endanger themselves. That just is not a realistic expectation of any person.

    Tl;dr - Physicians are just people and are not the ones that created this situation. They are normal people and expecting them to sacrifice career/freedom to help one patient is beyond what is realistic.

    Radiologist here. 👋🏻

    You are right it does not require contrast. The scan uses a special technique to reduce signal from tissue that isn’t moving so only things that are moving produce high signal and show up “bright.” Since blood is the only thing really moving in the brain - voila!
