Usually titanium, but yeah sometimes medical stainless steel. Both are non-ferromagnetic, especially titanium. These balls look like they could well be normal steel or any other metal. Also, implants - unlike these metal balls - are usually screwed firmly into your bones. So yeah, implants should be mostly fine on MRI. Loose balls of dubious metal? Wouldn’t advise it. Keep in mind MRIs are literally powerful enough that metals in tattoo ink can even be an issue - which the article you linked mentions itself.

In general, metallic orthopedic implants are not affected by MRI. 

This isn’t an implant though. Massive difference.

That only creates more questions 😅

When… what? 😂

Sorry, what exactly about Facebook marketplace? Too low prices, or too high? Or do you just mean the fact that theres no bidding on there? Haven’t been on there in a while so not sure what the correlation is.

Or the twist erase

Yeah but with mechanical pencils you can buy one and have it for years, only just buying the occasional pack of leads… Saves the trees ¯_(ツ)_/¯

I have two twist-erase 3’s and I’ve never looked back. I love them so much.

Sync for Lemmy, on Android. Tbh for some reason spoiler tags seem generally somewhat unreliable on Sync. Either way don’t worry about it too much.

Some searx instances have Tor as well ¯_(ツ)_/¯ But yeah, fair enough. I personally wouldn’t thrust a site with a massive dildo on the frontpage but to each their own haha
