Eli5 : Why cant you compare xrays to MRI’s ?
In: 0
Because they are completely different.
An x-ray is like a shadow. The X-ray go through your body, but are blocked by your bones. So on the other side, the only x-ray you see are those not blocked by your bones. Your bones cast an x-ray shadow.
An MRI work with big magnet that make your water molecules spin, which emit a radiofrequency that can then be detected. And MRI is basically a 3D map of your water molecules.
