What are other differences between CT and MRI?
Both CT and MRIs exams can be constructed “With or Without Contrast.” This refers to the dye or contrast agent that is either injected into or ingested by the patient. When the test is performed, the contrast allows the radiologist to see more clearly the image of a certain area or organ of the body. There are other more complicated differences than described here, especially in terms of how the tests actually work. If you would like more technical information of how CT and MRI works, please speak with your physician or visit our Links/Resources page. (In particular, the How Stuff Works site has a lot of good information; just enter “MRI” and “CT” at the site search.
