Abstract: Abstract Objective：To establish the PW (pulsed wave Doppler) normal waveform and reference range by detecting of abdominal pulsed wave Doppler on uterine arcuate artery of normal women of childbearing age. Methods: ①PW waveform was observed: According to having flow imaging during diastole , PW will be divided into bimodal peak、single-peak shape.; ②PW blood flow index was measured and the PW waveform and reference range of uterine arcuate artery were obtained by statistical analysis. Results: (1) 95.2% of the PW waveform of uterine arcuate artery with flow imaging during diastole showed bimodal shape. 4.8% without flow imaging during diastole showed a single-peak shape.; (2) PW reference range of uterine arcuate artery: Vs:3.5～44.0cm/s; Vd：0～11.8cm/s; PI:0.7～2.2; RI: 0.6～1. Conclusion: waveform analysis and RI were reliable and convenient, which could be used as important reference.
