Abstract

Background: Routine ultrasound study establishes itself as a major milestone of antenatal care if resources are facilitated to perform such studies in the second trimester though routine scanning is increasingly nowadays going to begin in the first trimester, particularly in high-resource circumstances.

Objective: detection of 4D ultrasound roles in the evaluation of the presence of fetal congenital malformations, in the 1st and 2nd trimester of pregnancy compared with 2D.

Patients and Methods: the study was conducted on 50 high-risk pregnant women (1st and 2nd trimester) some of them were examined in their 1st trimester, others were diagnosed in their 2nd trimester as part of fetal anomaly scan. part of routine maternal care, suspected cases will be advised to undergo 4D ultrasound and data were collected mainly from 4D Unit at Al-Hussien University Hospital.

Results: the study compared 2D ultrasound and 4D ultrasound in the detection of fetal anomalies. Fifty women with 56 fetuses were checked by 2D and 4D US, and 52 detected anomalies. Results show an advantage of 4D ultrasound over 2D ultrasound in 13% of the examined fetuses, equal findings noted in 30%, and limited information in 17% of the examined cases. Four dimensional US more useful in some anomalies of the face and extremities only.

Conclusion: according to our results, 3D/4D US appears beneficial over 2DUS in demonstrating facial and MSK anomalies.
