Abstract
The aim of this study was to investigate the usefulness of recording sonographic fetal scalp thickness (FST) to predict the estimated fetal weight (EFW), in third trimester of pregnancy. A cohort of 175 uncomplicated singleton pregnancies, at 27 to 40 gestational weeks, was included in this study. The FST was measured with sonography and defined as the distance between the fetal skin and the outer table, on a cross-section of the skull, along the parietal aspect of the fetal head. Measurements were taken twice, and the average of the measurements was recorded. The estimated fetal weight (EFW) was derived from the Hadlock’s formula. Simple linear and multiple linear regression models were performed to predict the EFW, based on the FST measures. A strong positive correlation was demonstrated between FST and the EFW (r = 0.65, P < .01). The regression equation, EFW = 4.6*FST + 2.27 was derived, with a unit increase in FST yielding a 4.6 unit rise in EFW. Fetal scalp thickness and the fetal femur length (FL) accounted for about 93% (R2 = 0.93) variability in EFW, while the fetal head circumference (HC) and FST accounted for 83% (R2 = 0.83) variance in the EFW. A potential may exist to use FST as a viable indicator of EFW and could be used in conjunction with current fetal biometric parameters to improve EFW prediction.

The Journal of Diagnostic Medical Sonography (JDMS) is the official journal of the Society of Diagnostic Medical Sonography and publishes peer-reviewed manuscripts aimed at the translational use of ultrasound for diagnosis, intervention, and other clinical applications. The JDMS provides research, clinical, and educational content for all specialties including but not limited to abdominal, women’s health, pediatric, cardiovascular, and musculoskeletal sonography. The journal’s scope may also include research on instrumentation, physics, ergonomics, technical advancements, education, and professional issues in the field of sonography. Types of submissions accepted by the JDMS are Original Research, Literature Review, Case Studies, Symposia (related to education, policy, technology, or professional issues), and Letters to the Editor.
