Abstract：Objective To study the method of improving sonographer 's skills during the first-trimester screening. Methods A total of 232 nuchal translucency measurement reports in Guangzhou were studied and compared with the standard of FMF. All key points of the images such as CRL, the proportion of fetal cephalothorax, posture of the fetus, the division among skin and amnion, location of the cursors were recorded. The results of different hospitals up to the standard were stud-ied. Results Among 232 records, 228 cases (98. 28%) of their CRL were suitable. There were 203 cases (87. 50%) clear-ly showed fetal lineament, 127 cases (62. 56%) imaging magnifications were not up to the standard, 76 cases (37. 44%) imaging proportions of fetal cephalothorax≥75%, 19 cases (9. 36%) showed median sagittal section, 107 cases (52. 71%) lay low, 67 cases (33. 00%) clearly showed the division among skin and amnion, 33 cases (45. 83%) showed the right loca-tion of cursors for NT measurement. The comparison of ultrasonographic image in nuchal translucency measurement between first-class hospitals and second class hospitals showed statistically significant difference (P<0. 05 or P<0. 01), except that CRL was out of range and cursors were in right location. Conclusion Training, experience of adequate practice and ongoing quality assessment are effective measures to improve sonographer's technological skills.
