MRI and CT are two important imaging tests that complement each other, and there is no such thing as which one is clearer, depending on which system is being used. MRI is preferred if the nervous system is to be examined, as it has higher soft tissue resolution and better contrast to show the cranial brain, spinal cord and other neurological aspects more clearly. If you need to observe bone changes, CT is recommended as the first choice, because it can more clearly see the changes in the bones, bone damage, etc.. Therefore, MRI and CT are complementary tests, and in many cases an MRI is needed to further refine the imaging after a CT is performed.
