Effective patient education in medical imaging: public perceptions of radiation exposure risk.

Patients perceptions of risk for harm influence their decisions concerning medical procedures and feelings of satisfaction with medical care choices. Radiologic technologists, dental hygienists, and other allied health professionals frequently are asked by patients to explain the radiation exposure dose and health risk associated with an imaging procedure. The purpose of this study was to evaluate the radiation risk perceptions within the community to develop an effective patient education strategy for health professionals based on the responses of 200 participants in a cross-sectional survey. Less than half of the adults responding to the survey agreed with experts regarding the risk of radiation exposure from various sources, and 75% to 90% of the responders thought that imaging providers should be highly educated and highly regulated. With efficacious patient education, appropriate risk comparisons can be made in simple terminology by addressing the public's knowledge, beliefs, and attitudes toward sources of radiation exposure.
