I've always wondered why they don't just have you walk through a metal detector before going near the machine. People are really fucking stupid and regularly get piercings ripped out. It's not even that I care about the tards that don't know their piercing is metal. The blood cleanup and potential damage to a million dollar machine ends up getting tacked on everyone's insurance bill. I also wish they'd do some studies on how MRIs affect blood pooling and stuff. They say it's safe but anyone with a degree in electrical engineering can tell you the field strength of the MRI is more than enough to affect the minuscule amount of iron in your blood. They also say gadolinium-based contrast agents are safe and they unquestionably are not.
