title: Normogram of fetal middle cerebral artery peak systolic velocity at 20-37 weeks of gestation at Srinagarind Hospital.
abstract: OBJECTIVE
  To establish normal references of fetal middle cerebral artery peak systolic velocity (MCA PSV) at 20 to 37 weeks of gestation at Srinagarind Hospital.
  
  
  METHODS
  A descriptive cross-sectional study was performed Normal fetuses at 20 to 37 weeks of gestation were studied by gray scale ultrasonography initially and then Doppler of MCA PSV.
  
  
  RESULTS
  At least 18 pregnant women of each gestational age with an uncomplicated singleton were enrolled The MCA PSV was increased as gestational age advanced from 24.34 cm/sec (SD 3.91) at 20 weeks to 59.04 cm/sec (SD 10.80) at 37 weeks.
  
  
  CONCLUSIONS
  A normogram of fetal MCA PSV at 20 to 37 weeks of gestation at Srinagarind hospital was generated.
