Utilizing sonography to follow fetal growth

Area of Science:

• Obstetrics and Gynecology
• Fetal Medicine
• Diagnostic Imaging

Background:

• Accurate in utero diagnosis of fetal growth abnormalities is crucial but challenging.
• Current antenatal diagnostic methods for intrauterine growth restriction (IUGR) and excessive fetal growth suffer from inaccuracies.
• False-positive and false-negative diagnoses complicate clinical management.

Purpose of the Study:

• To review the diagnostic challenges in antenatal assessment of fetal growth disturbances.
• To highlight the importance of utilizing multiple biometric parameters and serial measurements.
• To discuss the current benefits of diagnosing IUGR and the need for further research on macrosomia and large for gestational age (LGA) diagnosis.

Main Methods:

• Review of existing literature on fetal growth abnormalities.
• Analysis of diagnostic accuracy of various antenatal assessment methods.
• Evaluation of the clinical utility of serial biometric measurements.

Main Results:

• Antenatal diagnosis of fetal growth abnormalities, including IUGR and excessive fetal growth, remains imprecise.
• Multiple biometric parameters and serial measurements (every 2-3 weeks) can enhance diagnostic capabilities.
• Antenatal diagnosis of IUGR has demonstrated benefits in improving fetal outcomes.

Conclusions:

• Accurate antenatal diagnosis of fetal growth disturbances requires a comprehensive approach using multiple biometric parameters and serial assessments.
• Further research is needed to establish the benefits of antenatal diagnosis for macrosomia and large for gestational age (LGA).
• Improved diagnostic methods are essential to overcome current limitations in fetal growth assessment.
