I have permanent braces attached to the back of my teeth. I know they're magnetic, i can feel a slight pull if i hold a magnet close to them.

I don't know what i'll do if i ever need an MRI, otherwise i'd probably just find it cozy..

I have a simple hiatal hernia. One of the treatment options is to basically put a weighted band around your esophagus above the stomach so that the weight holds everything downward so your stomach doesn't get pulled up through the hernia. I imagined being in a car accident or some other situation where I'm nonresponsive, the doctor ordering an MRI, and me re-enacting the scene from Alien. Nah, I'll take my chances with the hernia, thanks.

Well - if it helps any - my understanding is that a doctor at an ER center would order a CT scan which is based on x-rays and can be done in a matter of a few minutes.

MRI scans are really reserved for things that don't image well on CT scans or when the resolution of a CT scan just isn't good enough. They also take quite a bit of time to perform.
