Brief Summary

The aim of this research was to examine the accuracy of transcerebellar diameter to abdominal circumference ratio (TCD/AC) and mid-thigh circumference and femur length (MTC/FL) in estimating the gestational age of healthy and abnormally growing fetuses.

Conditions

Transverse Cerebellar Diameter; Abdominal Circumference Ratio; Mid-Thigh Circumference and Femur Length Ratio; Gestational Age; Growth Restricted Fetuses

Outcome Measures

Primary Outcomes (1)

• Diagnostic accuracy of transcerebellar diameter to abdominal circumference ratio (TCD/AC) ratio

  Assessment of the diagnostic performance of the transcerebellar diameter to abdominal circumference ratio (TCD/AC) in predicting intrauterine growth restriction (IUGR)

  At the time of ultrasound examination (24-28 weeks of gestation)

Study Arms (2)

Group A

Pregnant women with normal fetal growth.

Device: Fetal Ultrasound Assessment

Group B

Pregnant women suffering from intrauterine growth restriction (IUGR).

Device: Fetal Ultrasound Assessment

Interventions

Fetal Ultrasound Assessment DEVICE

All enrolled pregnant women underwent a standardized obstetric ultrasound examination between 24 and 28 weeks of gestation.

Group A; Group B
