Essential Information

Radiologic technologists often specialize in one diagnostic imaging technique. To keep their certification credentials current, they need continuing education (CE) credits. Online-only CE programs are available. Admittance usually requires a degree or certificate in the field being studied.

Sonographic and nuclear medicine technologists are two types of radiologic specialists who require ongoing continuing education to maintain certification. Sonographers use diagnostic equipment that bounces high frequency sound waves off tissues, records echoes and transforms them into dynamic visual images. Nuclear medicine technologists use trace amounts of radiopharmaceuticals to obtain bone, tissue and organ data; a special camera records an image created by gamma ray emissions ( Each of these radiologic specialties has its own organization that offers certification. Multiple subspecialties are also practiced in each.

Program Information and Requirements

The rules governing maintenance of certifications are complex and subject to change. Sonographers and nuclear medicine technologists are advised to carefully choose among those recognized by their respective certifying organizations and the jurisdiction in which they practice.
