N2 - Objective: The study was undertaken to assess whether impedance to blood flow in the uterine arteries can be measured effectively by continuous wave (CW) Doppler compared with pulsed Doppler (PD). Methods: In a prospective double blind study, the resistance index (RI) was measured transvaginally in the uterine artery of 31 non-pregnant women in the first week post-menstruation, 30 min apart, by two different observers with two different instruments (PD and CW). The difference between the measurements was calculated and the waveforms compared. Results: There was no statistical difference in the mean RI values measured in both techniques. The waveforms recorded by the two instruments were identical. Conclusions: The uterine artery can be identified and the impedance to blood flow can be effectively measured in non-pregnant patients by CW Doppler.
