what was said,,,,,,
and also,,,, if you are looking to have one,,, its that machine that they slide you in what looks to be a tunnel.... and its very tight and constricting,,,, and you cant move......
hope you are not claustrophobic

A normal x-ray and a CAT Scan us radiation to take the picture and are gernerally used when looking for bone problems. Although they can pickup some larger tumors involving the bone areas. An MRI is for Magnetic Residence Imaging. As stated,it creates a magnetic field to completely map the area it is set to examine. Since it doesn't use radiation it is safer to use. The MRI can map the entire body and layer the image on the operators screen one cell at a time.

Magnetic resonance imaging (MRI), formerly referred to as magnetic resonance tomography (MRT) or nuclear magnetic resonance (NMR), is a method used to visualize the inside of living organisms as well as to detect the composition of geological structures. It is primarily used to demonstrate pathological or other physiological alterations of living tissues and is a commonly used form of medical imaging. MRI has also found many novel applications outside of the medical and biological fields such as rock permeability to hydrocarbons and certain non-destructive testing methods such as produce and timber quality characterization. The devices used in medicine are expensive, costing approximately $1 million USD per tesla for each unit (common field strength ranges from 0.3 to 3 teslas), with several hundred thousand dollars per year of upkeep costs.

Here is a couple of articles I found about MRI Scans...

Magnetic resonance imagery. Magnets are systematically passed around a part of the body. Variations in the magnetic field caused by the body's diff tissues create a 3D like image.

Stands for Magnetic Resonance Imaging. It's like an x-ray, but it shows more detail.
