Reproducibility of pulsed Doppler measurements of the maternal renal circulation in normal pregnancies and those with pregnancy‐induced hypertension

30 pregnant women between 28 and 36 weeks' gestation, including normal pregnancies and those affected by pregnancy-induced hypertension (20 patients for interobserver assessment, 10 patients for intraobserver assessment).

Color and pulsed Doppler ultrasound measurement of acceleration time and resistance index in the renal segmental and interlobar arteries.

Inter- and intraobserver reproducibility (intraclass correlation coefficient Ri) of acceleration time and resistance index.surrogate
