Bread For Brains

I was just researching MRI, and came accross it's full name [Magnetic Resonance Imaging ], and beside this I found the most hilarious way of describing how it works.

Think about a loaf of bread. You can’t see inside the loaf, so how would you go about finding out what’s in there? The simplest solution is to slice the bread and take a look; the thinner you slice the bread, the more of the bread you can see. And you can slice it many different ways; you can slice it the way you might to make a sandwich, or you can slice the entire top of the loaf off. Each of these slices gives you more information about what is inside the bread, and if you slice it enough times, you will know pretty much all there is to know about that loaf of bread That’s what an MRI does – it takes images of multiple slices and then can build an accurate 2-D or even 3-D image of the tissues in your body.

So now you know.
