The described image-scoring method represents a new approach towards the evaluation of ultrasound performance as a whole and nuchal translucency measurement in particular. It may be employed by every center in an independent manner with minimal resources and regardless of the method of risk assessment. More studies will be needed to determine the standards required from the examiners and to elucidate the contribution of the proposed auditing method to the examination's quality and the process of training.

Implementation of an ongoing audit, using the image-scoring method, proved to be an efficient method for surveillance and improving the quality of nuchal translucency images. We recommended centers or individuals practicing first-trimester ultrasound screening to consider its routine utilization, in an unbiased and strict manner.
