Welcome to IWETHEY!

New Am I imagining...
...or do I remember something about an MRI giving a radiation dose roughly equivalent to an x-ray?
"Here at Ortillery Command we have at our disposal hundred megawatt laser beams, mach 20 titanium rods and guided thermonuclear bombs. Some people say we think that we're God. We're not God. We just borrowed his 'SMITE' button for our fire control system."
New You might be thinking of a CAT scan.
MRI = Magnetic Resonance Imaging. Used to be called Nuclear Magnetic Resonance. You put something in a strong magnetic field, the nuclei in the material align their magnetic moments to the field. When you remove the magnetic field, the nuclei relax and give up some photons. The photons give information about the material.

There's no ionizing radiation in MRI scans. There's just a very big magnetic field (and that makes lots of people nervous).

In CAT scans (Computerized Axial Tomography), lots of X-ray slices are made and a computer assembles the information and gives cross-sectional information.

Google gives lots more information. :-)

Cheers,
Scott.
New Ah.
Was hoping that could be a possible "excuse" for keeping people out of the chair.
