Three credentialing organizations offer similar but different different
pathways to your individual credentialing in a specific field of
practice:
• American Registry of Diagnostic Medical Sonographers (
ARDMS)
• American Registry of Radiologic Technologists (
ARRT)
• Cardiovascular Credentialing International (
CCI)
The ARDMS offers credentialing exams in every area of sonographer
practice, including the voluntary Registered Physician Vascular
Interpretation. CCI offers exams in the field of echocardiography and vascular sonography, as well as non-ultrasound credentialing. The ASRT
credential in ultrasound is available only to members of the ASRT; get more information on it by clicking on the link above.
