There are not ethical issues associated with CT scans because it is essentially a x-ray that is more accurate. It is painless but a contrast material will be injected or digested into the patient so there is a clearer image. They may feel warm or flushed after taking the contrast material when injected. If it is digested, there is a metallic taste to it. The scan has a varying but mostly large amounts of radiation depending on how much of the body is scanned. Children are more sensitive to radiation so it is advised to not CT scan youth unless necessary. Other than the possibility of cancer, the doctor will know what you have and you will be treated correctly. The chart below shows the amount of radiation for each scanning method. CT scans are the highest because of the 3D method of scanning. Underneath is a CT scan of lungs from two angles.
