Results showed decrease of S/D ratio and PI for UA, UtA from 8 to 40 weeks of gestation and PI for RA from 20 to 40 weeks of gestation. S/D ratio and PI for A was not changed during second half of normal pregnancy. S/D ratio and PI for MCA were increased from 20 to 30 weeks of gestation and after that had tendency of decreasing to term.
