%X Objective To examine the value of color Doppler flow image（ CDFI） in the screening of first-trimester fetus. Methods Two thousand and three hundred and eighty cases in first-trimester were screened by the color Doppler ultrasonography. Results A total of 2426 fetuses included 46 twins. Twenty- eight fetuses were abnormal including 8 cases of NT~〉3.0 mm and llcases of NT~〉3.0 mm with the other abnormalities. Eight cases of abnormal anatomical structures included 1 case of multiplicitas, 1 case of ceph- alocele, 1 case of partial hydatidiform mole, 1 case of choroid plexus cysts ,4 ease of central nerve system ab- normalities（ 3 cases of exencephaly , 1 case of anencephaly）and 1 case of reversal ＂A＂ wave in ductus veno- sus flow. Conclusion The Color Doppler ultrasonographic examination can provide the important hereditary information for prenatal screening of first-trimester fetus and screen fetal serious abnormal anatomical struc- tures.
