Some may assume that the MRI and the CT Scan are the same because of how they are used, but there are certain differences that should be noted. The CT scan makes use of X-rays in order to get images of the inside of the body while the MRI will use magnetic fields and radiofrequency so that the images of the body’s internal organs will be shown.

CT Scan still uses radiation while the MRI does not use radiation. The CT Scan can be used to see the full body in general while the MRI can be used for some specific portions of the body, particularly the soft tissues. The MRI is considered to be safer but is also more expensive than the CT Scan.
