what is the difference between an mri and a ct?

MRI/CT: A CT scan uses x-ray radiation to generate an image. An MRI uses magnetic fields "tuned" to the frequency of protons in the body. Since each scan essentially measures a different property of tissues in the body, they are complementary tests. That is why if one doesn't provide a definitive answer, often the other will be ordered.
