Can anyone tell me the difference between an MRI and a CT scan?
Thanks,

Here's the basics of MRI: http://www.cis.rit.edu/htbooks/mri/inside.htm

And the CT scan: http://imaginis.com/ct-scan/

I was going to post it all in here, but there are lots of things on these two sites that I think may interest you.

Hope this helps.

The only difference that I see in the MRI (magnetic resonance imaging), and a CT scan (computerized tomography), is that with the MRI, it goes through the whole body, point by point, and can pick up every small point.

With a CT scan, it only picks up certain parts of the body, as the machine moves around. A dye is injected in the vein, for the scan.

I'm sure you will get a better medical answer from someone else, but this is just from personal experiences with me.

Thanks for the info. It's made things a little more clear to me.

They are very different ways of getting an image: MRI analyzes response to a high magnetic field, and CT is your basic xray, penetrating tissues and enhanced by a computer. Both can image any part of the body. In certain circumstances, each is used with dye. Because
CT is faster, it's less affected by motion, and is therefore better at imaging things that move some, like the guts. CT more or less gives an image of what something looks like, and to some extent of its blood supply. MR, because it analyzes molecular characteristics, can in some cases give more info about what a particular tissue is, as opposed to what it looks like.

Thanks for the answer Sid.

golly sid you the man...i work with both and i couldn't have said it better my own self.
