Ever wonder why a hospital’s radiology, ob-gyn, or ultrasound department or this practice is "accredited"? And what does it mean when a sonographer says he or she is "credentialed," "registered," or "certified"?

To be "registered," "credentialed," or "certified" by the American Registry of Diagnostic Medical Sonographers (ARDMS) means a sonographer has consistently demonstrated professional standards, as well as achieved a level of competency in both technical procedures and patient care. ARDMS-certified sonographers must maintain their credentials by fulfilling continuing competency education requirements that serve to enhance their knowledge and keep their skills up-to-date. This ongoing education is critical because the field of ultrasound (sonography) is advancing so rapidly.

The American Registry of Diagnostic Medical Sonographers (ARDMS) has been certifying sonographers for more than 25 years. To achieve ARDMS certification, an ultrasound professional must meet high standards, in terms of classroom learning, as well as clinical skills. In addition, he or she must pass a rigorous ARDMS examination that tests both theoretical and clinical know-how. Many of the questions are based on actual patient cases.
