AB This  chapter  focuses  on  the  Doppler  interrogation  of  the  fetal  circulation.  Other  chapters  in  this  book  focus  on  Doppler  velocimetry  of  the  uterine  arteries  and  fetal  echocardiography.  Randomized  clinical  trials  have  demonstrated  that  Doppler  examination  of  the  umbilical  arteries  can  reduce  perinatal  mortality.  Therefore,  practitioners  need  to  be  familiar  with  the  sampling,  interpretation,  and  clinical  significance  of  these  vessels.  Similarly,  Doppler  examination  of  the  venous  system  (ductus  venosus,  inferior  vena  cava  [IVC],  and  umbilical  vein)  are  informative  of  cardiac  function  and  identify  a  fetus  at  risk  for  impending  in  utero  death.  Finally,  examination  of  the  peak  systolic  velocity  of  the  middle  cerebral  artery  has  become  important  in  the  assessment  of  fetal  anemia.  This  chapter  reviews  the  anatomy,  physiology,  Doppler  waveform  morphology,  normal  ranges,  and  interpretation  of  an  abnormal  waveform  in  clinical  practice.
