  • Not sure why you’re being downvoted. Overall I agree heavily with what you are saying. I really was hoping for the feeling of whiplash when Biden took office because I expected him to drop like 20 executive orders on day 1 to undo the worst of the worst Trump shit. No reason not to have that shift drafted and ready to go before inauguration. But it didn’t really play out that way.

    I hope hope hope that if they manage to take back the White House and Congress that the democrats have an agenda ready to rock and roll because that otherwise it’s hard to maintain enthusiasm from the public when it seems like not much is happening.

    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!











  • I don’t think that’s true at all.

    I realize the geometry predicts some optimal spot for viewing the curve but that just is a mathematical ideal not a real world necessity. If it was then everyone who has ever watched a flat screen would be like “omg I feel like I’m too close because I’m not watching from infinity.” I have a 35” monitor with 1800R and it is very pleasant in a normal desktop setting. I looked into 1000R screens since I like to sit fairly close and the curve felt so extreme that it was a major distraction no matter which distance I sat at.

    I guess I’m saying that the curvature is very much a personal preference thing and if people can tolerate a flat screen they can also tolerate a curve that isn’t meeting some mathematical ideal.
