Answer to Question 1

CT:
 produces images of the body in cross section by rotating an X-ray tube around the patient at various levels
 patient is exposed to radiation and uses ionizing radiation to reconstruct the data into an image that reproduces the patient's anatomy as a cross-section picture
 images appear white (dense tissues) and dark (less dense tissues) as in an x-ray with sharper images produced for tissues separated by planes of fat (low density)
MRI:
 produces computer-constructed images using a device that consists of a strong magnet; the images depend on the response of hydrogen protons contained within water molecules when they are placed in a strong magnetic field
 does not expose patients to radiation

Answer to Question 2
