Doppler assessment of the ductus venosus and the tricuspid valve at 11-13+6 weeks: Reference ranges and development of sonographic quality assurance standards
Abstract:Objective: To develop reference ranges for the ductus venosus (DV) and tricuspid valve (TV) waveforms at 11-14 weeks and define auditable standards to assess operator measurement performance. Materials and methods: A single operator prospectively obtained quantitative measurements of a number of DV and TV Doppler indices to develop medians and 90% reference intervals (RIs). Measurement agreement studies between two experienced operators were also performed. The measurement bias of three additional operators wa… Show more
