The ASN examination in Neurosonology is designed to assess a physician's ability to apply knowledge, concepts, and principles of neuroimaging that constitute the basis of safe and effective patient care. They are designed to assess whether the candidate can apply the medical knowledge and understanding of biomedical and clinical sciences considered essential for the unsupervised practice of neuroimaging. The Neurosonology Proficiency Examination is not based on the review course in Neurosonology given at the ASN Annual Meeting. The course does not cover the entire content of the exam. Examinees are encouraged to use the Orientation and Suggested Readings to prepare for the exam.

At the ASN January 2010 Board Meeting, the ASN Board of Directors approved a maintenance of certification policy that will become effective January 1, 2011. It will apply to all future ASN Neurosonology Exam diplomates.

All ASN certificates issued after the January 2011 Neurosonology Exam are time-limited, expiring on January 31st of the 3rd year after the date of issuance. There are three requirements that must be met during the 3 year cycle in order to be recertified for another 3 year period. The diplomate must:

1. Maintain a current, active, valid, unrestricted, and unqualified license to practice medicine;
2. Continue to be in good standing in the primary specialty of an ABMS member board that was required for eligibility when he or she applied for initial ASN certification (does not apply to foreign diplomats); and
3. Complete 15 category 1 CME hours specific to ultrasound.

Please see CME Opportunities page for additional resources.

PLEASE NOTE: You must submit all of the above documentation in a single pdf during the registration process. If you are registering as a physician in training, you must also include verification of your training status. Please have your documents ready before you register.

If you are unable to take all three parts of the exam on the date of the initial exam you have the option to take the third part at an additional charge within two years. For example: If you have 100 TCD AND 100 carotid cases, you can take all three parts in one day. If you only have 100 TCD cases, you can take two of the three portions of the Neurosonology examination and have the option to take the third part on carotids at anytime within 2 years at an extra charge.

* Those who have not yet received Board Eligibility/Certification or medical license at the time of the examination will receive their results upon providing supporting documentation *
