Doctors order\u00a0CT scans<\/a>\u00a0or\u00a0MRI scans<\/a>\u00a0to help diagnose a wide range of medical conditions. Both types of scan have similar uses, but they produce images in different ways. A CT scan uses X-rays, whereas an MRI scan uses strong magnetic fields and radio waves.<\/p>\n

CT scans are more common and less expensive, but MRI scans produce more detailed images.<\/p>\n

In this article, we look at the differences between CT scans and MRI scans, as well as their uses, procedures, and safety.<\/p>\n

Both CT scans and MRI scans allow doctors to see internal body parts.<\/div>\n<\/div>\n<\/div>\n<\/div>\n

CT scans and MRI scans are two different ways of creating detailed images of internal body parts. Doctors can then analyze the images to detect abnormalities, such as\u00a0fractures<\/a>\u00a0in bones, tumors on organs, or joint damage.<\/p>\n

Some people refer to a CT scan as a CAT scan, which stands for computerized axial tomography. During a CT scan, a person lies down in a large X-ray machine called a CT scanner. The scanner sends images to a computer.<\/p>\n

MRI stands for magnetic resonance imagery. This type of scan uses radio waves and magnets to create images. During an MRI scan, a person lies down in an MRI scanner, which is a machine that creates a constant magnetic field and uses radio waves to bounce off water molecules and fat cells in the body. The scanner also sends images to a computer.<\/p>\n

CT scans are more common and less expensive than MRIs. However, MRI scans produce a better image than CT scans.<\/p>\n

What are their uses?<\/h2>\n

The uses of CT and MRI scans are very similar. CT scans are more common because they are less expensive and still provide good detail. A doctor may order an MRI scan when they need to create more accurate, detailed images of the body.<\/p>\n

Common uses for a CT scan include examining or looking for:<\/p>\n
