MRI, is magnetic resonance imaging. It provides a much more detailed soft tissue analysis than anything other than exploratory surgery. The machine generates a magnetic field, then records the resonance of the soft tissue being examined. Normal tissue resonates in a magnetic field differently than damaged or mutated tissue (read cancer). This image can be very detailed and provide a medical professional with a powerful diagnostic tool.

Diagnostic medical imaging technique utilizing the principles of nuclear magnetic resonance. The principle of MRI is applicable in the human body because we are all filled with small biological magnets, the most abundant and responsive of which is the nucleus of the hydrogen atom, the proton.
MRI is viewed by many as the most versatile, powerful, and sensitive diagnostic imaging modality available. Its medical importance can be summarized briefly as having the ability
to non-invasively generate thin section, functional images of any part of the body at any angle and direction in a relatively short period of time.

unlike x-ray, which provides a density-based contrast (dense bones are white, and soft tissues are dark), the contrast of mri is configured by the operator and depends on the parameters of the particular sequence chosen for imaging. for example, some contrasts are diffusion-weighted (dark regions have lots of diffusion, white regions have less) which can be useful for seeing tumors, fine brain structures etc, other contrasts differentiate between watery and fatty tissues (and can thus be used to find various pathological anomalies), other contrasts are based on magnetic susceptibility and can be used for observing changes in tissue oxygen levels. the vast range of contrasts and the ability to view images in 3D, non-invasively and without the dangers of radiation from x-rays and contrast agents used in CT/xrays, makes mri a very powerful tool for doctors and researchers

The MRI can give a clearer picture of your insides then any other machine out there. The images captured are much more detailed then CT or x-rays.

because it is able to see underneath like an X ray, and seeing what the problem is is one of the first steps to good treatment.
