• Welcome to Bone Densitometry Online

    This site is designed to help bone densitometry candidates prepare for the ARRT Limited Bone Densitometry Equipment Operator Examination for state licensing or the ARRT Registry Examination in Bone Densitometry for national certification.

    Candidates for the ARRT Registry Examination in Bone Densitometry for national certification are required to meet the Professional Education Requirements specified in the ARRT Rules and Regulations. This education requirement for earning a credential using the postprimary eligibility pathway includes:

    • Being ARRT certified and registered in an appropriate supporting category. In some cases, your certification by the Nuclear Medicine Technology Certification Board (NMTCB) or the American Registry for Diagnostic Medical Sonography (ARDMS) can count as your supporting category
    • Meeting the structured education requirement: Candidates for Bone Densitometry certification and registration must document at least 16 hours of structured education through My ARRT Info account on arrt.org. Structured education documentation must include at least 1 CE credit in each of these content areas: Patient Care, Image Production, and Procedures, for a total of at least 16 hours.
    • Meeting the clinical experience requirement
