Epidemiology for the Nuclear Medicine Technologist

Nuclear Medicine Technology Program, Division of Medical Imaging and Therapy, School of Health Related Professions, University of Alabama at Birmingham, Birmingham, Alabama

Objective: The purpose of this article is to introduce the nuclear medicine technologist to the field of epidemiology. There are many applications of epidemiology in nuclear medicine, including research studies that deal with the causes of disease or ways to prevent disease from occurring and investigating the possible effects of ionizing radiation on occupational workers and the general public. One use of an epidemiologic study is to suggest ways to reduce the occurrence of a disease. After reading this article, the nuclear medicine technologist will be familiar with: a) the history and underlying assumptions of epidemiology, b) types of epidemiologic studies, c) what is a valid statistical association for an epidemiologic study, d) proper judgment of cause and effect relationships, e) definitions of epidemiologic terms, and f) an example of a nuclear medicine research study.

Key Words: epidemiology; nuclear medicine; radiation studies; valid statistical association; cause and effect relationships; prospective and retrospective studies; biostatistics.
