Herman score in prenatal screening for Down syndrome: Can a junior assess a senior?

Purpose: To compare Herman scores self-assessed prospectively during ultrasound first-trimester screening by a single senior radiologist with 15 years of experience, to those obtained retrospectively by an unexperienced junior radiologist.

Materials And Methods: Over a 18-month period, a single senior radiologist measured the nuchal translucency thickness along with calculation of Herman scores. An independent junior radiologist subsequently reviewed and scored the images.
