Each pathway has requirements for a minimum amount of MSUS ultrasound CME credits and MSUS scans performed.
Credits earned outside of the required “at least 14 AMA PRA Category 1 Credits™ from a single course that includes hands-on scanning practice” must be AMA PRA Category 1 Credits™ specifically related to MSUS.
In case of application audit, a copy of the earned CME certificate(s) must be submitted.
For more information see RhMSUS ™ CME Activity Checklist in Appendix E of the Candidate Handbook (pg. 22).
Ultrasound scans can be limited or complete, diagnostic, or therapeutic. For each unique patient/subject/model, no more than one scan per day can be logged.
In case of application audit, a log with the information included on the Sample Patient/Practice Scan Log or a billing log (both without identifying information in conformity with HIPAA) must be submitted for proof of the number of scans completed.
Applications are accepted on a continual basis and candidates can select their desired testing window during the application process. Candidates are strongly encouraged to complete their applications at least 60 days prior to the desired testing date.
The examination is offered twice a year in the spring and fall during a one-month window. If a candidate misses the deadline, his/her application will be credited toward the next window.
The certification registration fee includes the processing of the application, examination registration, and one testing appointment.
All requirements for your selected pathway must be completed prior to submitting your application for the examination. During the application, candidates must upload a copy of their medical license and attest that they can provide documentation (e.g. copies of earned AMA PRA Category 1 Credit™, scan/billing log, etc.) that supports their compliance with the eligibility criteria for the selected pathway.
Candidates must complete an online application and a multiple-choice, computer-based examination.
The examination will take place at Castle internet-based testing sites located throughout the United States. Thirty days before the testing window opens, a Castle representative will contact you by email to schedule your examination. Seats are filled on a first-come, first-served basis, based on test center availability.
Candidates can take the examination at an international testing site for an additional $150 that will be collected at the time of scheduling.
The examination consists of 100 multiple-choice questions based on the following domains.
The Candidate Handbook contains the following resources to help you prepare for the examination.
To help you become familiar with the computer-based testing system, Castle provides an online demonstration and tutorial that is accessible anytime, anywhere. This demo is not a review of the RhMSUS™ examination content.
Examination results are mailed to the address provided on the application approximately six weeks after the testing window closes. Examination results will be released only in writing by mail. Examination results will not be released by telephone or fax. Candidates who need to update their mailing address should contact Castle at firstname.lastname@example.org.
Candidates who pass the examination will receive a personalized certificate and wallet card.
A percentage of candidate applications will be audited to ensure compliance with the eligibility criteria. Applications for audit will be selected randomly. If your application is selected for audit, you will receive instructions on how to supply satisfactory documentation that supports your compliance with the eligibility criteria before your certificate is released.
Candidates who do not pass the examination may retest in the next testing window. Candidates may not take the examination more than two times in any 12-month period. Candidates who need to retest will receive a Notice to Schedule email 45 days before the next testing window. During the scheduling process, candidates will be prompted to pay the retake fee of $100.
Recertification is required at ten-year intervals effective on the date of RhMSUS™ certification. To complete the recertification process, the candidate must complete the following:
