MRI Versus CT - Both Techniques Have Some Advantages over Each Other Doctors find MRI scan best for soft tissue images while for scanning bones, CT scan works much better. Unlike X-ray machine CT scan uses a beam of light instead of single ray of light and some time causes damage to DNA, if exposed to body for longer time.
