Systematic assessment of the impact of routine third-trimester ultrasound examination has provided robust estimates of its diagnostic accuracy for various fetal anomalies, as well as some adverse perinatal outcomes. Read the latest Practice Guideline to find out more.


This new Practice Guideline makes recommendations for conducting third-trimester ultrasound examinations and is free to download. It addresses:


  • The determination of placental location and fetal presentation, measurement of fetal biometry, identification of fetal anomalies, evaluation of amniotic fluid volume and documentation of fetal and uterine artery Doppler findings.

  • Third-trimester screening for small-for-gestational age and macrosomia.

  • The gestational age at which the routine third-trimester ultrasound scan should be performed.

  • Situations such as suspected vasa previa, or the combination of low-lying placenta and previous Cesarean section, in which additional steps and detailed assessment should be included in the third-trimester ultrasound scan.
