Reliability of amniotic fluid volume estimation from ultrasonograms: Intraobserver and interobserver variation before and after the establishment of criteria

This study assesses levels of intraobserver and interobserver agreement for the determination of decreased and normal amniotic fluid volumes, both before and after the development of criteria. Good to excellent levels of agreement were obtained. Agreement may be higher after the development of criteria and may be higher for more experienced ultrasonographers.
