The AIUM/ACR antepartum obstetrical sonographic guidelines: expectations for detection of anomalies

A survey was sent to 52 physicians considered experts in obstetrical sonography asking them to comment on the probability of observing various fetal abnormalities when the AIUM/ACR guidelines for a level one obstetrical sonogram were followed. Although definite trends were noted in several areas, there was much diversity in opinion concerning what should or should not be seen when the guidelines were followed. Given the fairly specific nature of the AIUM/ACR guidelines, we were uncertain why the responses were not in more uniform agreement.
