It has been argued that informed consent should be obtained from all patients to provide them with correct information about the radiation exposure and lifetime cancer risk as they are currently understood to respect patient autonomy [20-22]. Although most academic medical centers currently have guidelines for informing patients regarding CT scans, its purpose, and some risks, they are not obtaining full informed consent because of the failure of disclosing both the radiation risks and diagnostic alternatives. Of the centers that provide risk-related information to patients, radiology technologists were the most likely source of this information, followed by attending radiologists. Thus, if radiology technologists continue to play a large role in the consent process it is important that the radiology community ensure that technologists are educated and trained to provide necessary information to patients concerning the risks, benefits, and alternatives to CT scans.

CONCLUSION. Although the United States has no current national guidelines for informing patients about radiation exposure with diagnostic CT scans, the European Union has codified into law the requirement that all CT dose information accompany electronically stored image data for patients and that anyone referring a patient for a radiologic examination must provide “sufficient medical data” to justify the study [24, 25].
