ExploreAbout this exam
The American Society of Neuroimaging (ASN) describes certification as a way to "recognize advanced expertise and professional achievement" for neuroimaging professionals, and its site lists two currently offered credentials: Neurosonology (RPNI) and Neurovascular Specialist (NVS). A separate "Neuroimaging Examination" is announced on the ASN site as "Coming 2027!" and is not yet available, so candidates today should plan around RPNI or NVS. The ASN describes itself as representing "clinicians, researchers, and technologists worldwide" and as having advanced education, certification, and collaboration in neuroimaging since 1977, which suggests the certifications are aimed at practicing physicians, sonographers, and technologists who already perform or interpret neuroimaging studies. Preparation should center on supervised hands-on scanning and interpretation experience plus the reading and continuing-education resources the ASN publishes, including its journal, monthly newsletter, webinars, and Educational Rounds. Because ASN publishes separate examination and maintenance-of-certification pages for RPNI and NVS, candidates should read those pages directly for current eligibility, content outline, and recertification requirements before registering. This page is an independent study resource and is not affiliated with or endorsed by the ASN; verify all details against asnweb.org before applying or scheduling.
What you'll study
About ASN CNSA preparation
Which neuroimaging certifications can I actually sit for right now?
The ASN lists two certification exams on its site: Neurosonology (RPNI) and Neurovascular Specialist (NVS). The separate Neuroimaging Examination is announced as coming in 2027 and is not yet available. Plan your study around RPNI or NVS unless you intend to wait for the new exam.
How much does the exam cost, and how long is it?
The ASN pages retrieved for this profile do not state a fee, question count, or time limit for either exam. Rather than guess, confirm these details with the ASN directly through the contact information on asnweb.org before you budget or schedule.
What score do I need to pass, and how long is certification valid?
The source material does not publish a passing score or a validity period. The ASN does maintain dedicated Maintenance of Certification pages for both RPNI and NVS, so read those pages for recertification intervals and requirements, and ask the ASN about scoring before your test date.
Is the exam offered online or in person, and when?
The retrieved ASN pages do not describe delivery format or testing windows for RPNI or NVS. Check the individual examination pages and contact the ASN for current scheduling. Do not assume a date based on the Annual Meeting, which is a separate educational event.
How hard is it, and what trips candidates up?
Expect applied, image-based reasoning rather than pure recall, since the credentials target people who already scan and interpret. Common failure modes are weak hands-on scanning volume, shaky vascular anatomy and hemodynamics, and skipping the physics and artifact fundamentals that explain confusing images. Build supervised case volume early.
How should I order my studying?
Start with normal anatomy and normal hemodynamics, then layer in pathology and interpretation pitfalls, then timed practice on unknown cases. Use ASN education resources such as the journal, webinars, and Educational Rounds alongside hands-on scanning. Keep a log of cases you misread and revisit them weekly.
If I fail, can I retake it, and does it cost extra?
Retake policy and any associated fees are not stated in the source material reviewed here. Contact the ASN before registering so you understand the retake window and cost, and factor a possible second attempt into your study timeline.
Does this page come from the ASN?
No. This is independent study material and is not affiliated with, endorsed by, or sponsored by the American Society of Neuroimaging. All official rules, dates, and requirements come from asnweb.org; verify everything there before you apply, pay, or schedule.
