Neurovascular Specialist (NVS) Examination
Upcoming Examination Dates:
ASN 2020 Neurovascular Specialist (NVS) Exam
ASN 2021 Neurovascular Specialist (NVS) Exam
The American Society of Neuroimaging (ASN) “Neurovascular Specialist” examination (NVS) will require an individual’s ability to apply the knowledge, concepts, and principles of neurovascular technology in the fields of Transcranial Doppler (TCD) and Carotid Duplex ultrasound. This includes the analytical skills and tasks performed that constitute the basis of safe and effective patient care. It is also designed to assess the candidate’s ability to apply the understanding of biomedical and clinical sciences that are considered essential for the practice of neurovascular ultrasound.
The NVS examination is offered to assess proficiency in neurovascular ultrasound and will include three components: Basics of Ultrasound and Ultrasound Physics, Transcranial Doppler, and Carotid Duplex. It is intended for individuals who have training and experience in neurovascular ultrasound. Individuals who apply should have a basic foundation in the principles, physics, technique, and clinical implications of neurovascular technology in order to acquire, understand, and present the data to a supervising physician. As an incentive for individuals who have already completed their “Physics and Instrumentation” examination from the ARDMS, CCI, or ARRT (VS), the “Basics of Ultrasound and Ultrasound Physics” component of the NVS examination will be waived.
The NVS proficiency examination is not based on the review course in basic neurosonology given at the ASN Annual Meeting. The course does not cover the entire content of this examination. Examinees are encouraged to use the “ASN Outline of Core Curriculum in Neurosonology” to prepare for the exam.
To be eligible for the Neurovascular Specialist (NVS) examination, a candidate must provide all required documentation and meet the following criteria:
- Completion of a minimum of a two-year allied health education program that is patient-care related; a Bachelor’s degree; Master’s degree (or equivalent) OR an Active RVT, RVS, RDMS, or ARRT (VS) specialty credential. Individuals holding a certificate in Intraoperative Neuro-Monitoring (IONM), Advanced Practice Providers, and Critical Care Nurses are eligible assuming they meet ALL of the other requirements.
- 12 months of full-time (or equivalent) clinical experience performing ultrasound.
- Performance verification of at least 100 supervised studies for each component to be tested (e.g. TCD and Carotid Duplex) accompanied by a hand-signed, original letter from either a supervising physician, supervising sonographer, or an Educational Program Director, attesting to the length and scope of ultrasound experience.
- Documentation of a total of 30 CME/CEU credits, 15 credits specific to each credential area sought (15 for TCD/ 15 for Carotid Duplex)
• Wake Forest School of Medicine (Winston-Salem, NC)
• Swedish Medical Center (Seattle, WA)
• Cedars Sinai Medical Center (Los Angeles, CA)
• Gulfcoast Ultrasound Institute Inc. (St. Petersburg, Florida)
All exam applicants must pre-register, submit their documentation, and pay their registration fee by the registration deadline, or their registration will NOT be accepted. Orientation materials outlining the recommended references and study guides can be downloaded.
Delayed Certification Option
If you are unable to take all 3 components of the exam on the same date as the initial exam, please contact the ASN office at firstname.lastname@example.org for delayed certification options.
Maintenance of Certification
Upon successful completion of the examination, all Neurovascular Specialists will be required to maintain an ASN membership to keep the certification active. Those certified must also acquire 30 CME credits specific to the field of neurovascular ultrasound every three years.
