About

The purpose of the study to evaluate Five-Dimensional Ultrasound in automated measurement of the fetal femur length at third trimester of pregnancy.

Full description

This is a Prospective pilot study that will be performed at the Fetal Care Unit at Ain Shams University Maternity Hospital.

Ninety pregnant women will be recruited from the the Fetal Care Unit who will fulfill the inclusion criteria. They will be counseled to be included into the study.

All cases will be subjected to:

1. Full history taking including patient's age, parity, last menstrual period, estimated gestational age by dates, past history of medical disorders, clinical examinations (General and abdominal).
2. Two-Dimensional Ultrasound and Five-Dimensional Ultrasound will be done for all cases for assessment of fetal femur length .

The FL at Two-Dimensional Ultrasound (Gold standard) will be made from the center of the 'U' shape at each end of the bone.

The FL at Five-Dimensional Ultrasound will be measured by Pressing Five-Dimensional Ultrasound long bone Button to extract Fetal Long Bones automatically.

The estimation of gestational age by femur length by Two-Dimensional Ultrasound and Five-Dimensional Ultrasound will be compared to gestational age calculated by accurate dates of the last menstrual period.
