» P_Al - MRI vs Mammogram

In response to Role of MRI in Breast Cancer posted by tinuviel:


A mammogram is really an x-ray of the breast. This uses 'fairly' simply technology - passing x-rays through tissue to produce an image on a film. This is similar to taking a photograph.
.
On the other hand, an MRI requires the use of radio waves, a powerful and very expensive magnet and a computer. The radiowaves, applied by the machine, interact with atoms in the tissue. These release excess energy that is again picked up by the machine and sent to the computer for analysis. This is a much more complicated system.
