The value of the early pregnancy ultrasound in the past was confined for assessment of gestational age by accurate estimation of the crown-rump length, detection of fetal viability, diagnosis of twins and determining their chorionicity with its great impact on the fate of the twin pregnancy.Recently, with the great advances in the technology of ultrasound, fetal anatomy scan in late first trimester was suggested and applied.In the first attempts, most of the attention was directed to the high risk group or selected populations, but in the recent literature, the low risk pregnancies were also included.Its wide acceptance and application made it prudent to study its real potentials in the detection of anomalies in comparison with the standard mid-trimester fetal anatomy scan.The aim of this study is to evaluate the ability of early trimester scan (11- 14 weeks) , both TAS and TVS to accurately visualize fetal organs as well as depict major fetal anomalies.
