this study aims to help the physicians to evaluate the practice of routine Third trimestric fetal scan whether it should be routinely performed to all cases including those with low risk singleton pregnancies.

The third-trimester ultrasound scan ,traditionally performed at 32-34weeks, can assess fetal viability , presentation, anatomy , growth, amniotic fluid volume, placental location and fetoplacental Doppler.

There are multiple other indications that can trigger a third-trimester scan, including antepartum bleeding , reduced fetal movements, preterm rupture of the membranes and suspected abnormalities of fetal growth based on physical examination. In addition, ultrasound may be used to guide other procedures in the third trimester, such as external cephalic version. However, as yet, there is no convincing evidence that routine universal third-trimester ultrasound examination in a low-risk population improves either perinatal or maternal outcome especially in low socioeconomic countries with limited resources

Inclusion Criteria:

• Singleton healthy pregnancy at second and third trimesters of pregnancy.
• Fetuses were considered normal based on second trimestric fetal scan in our feto-maternal unit

Exclusion Criteria:
