The new normal ICA PSV according to IAC is which value?

Explanation:
Velocity in the internal carotid artery is used to gauge stenosis, but normal ranges have evolved with newer guidelines. The IAC’s updated reference sets the upper limit for normal ICA peak systolic velocity at 180 cm/s. This means values below 180 cm/s are considered within the normal range, helping prevent overcalling mild changes as disease in high-flow states or with modern ultrasound performance. In practice, you’d still consider other factors—such as end-diastolic velocity, the ICA/CCA velocity ratio, and plaque characteristics—before labeling any stenosis. Since the question asks for the new normal per IAC, the threshold is less than 180 cm/s.
