Abstract
Objectives: The aim of this study was to evaluate whether transcerebellar diameter (TCD) in singleton gestations can serve as a
reliable predictor of gestational age (GA) in fetuses in the third
trimester between 31-36 weeks of pregnancy in women attending the
antenatal care clinic for routine ultrasound examination. Patients and
Methods: This was a prospective observational study conducted on
pregnant women attending our ultrasound unit for routine antenatal
care at Benha University Hospital. The study was conducted after
obtaining approval from Local Ethics Committee on research involving
human subjects of Benha Faculty of Medicine form December 2021 to
October 2022. Results: There was statistically significant positive
correlation between GA by LMP with GA by BPD and GA by TCD,
GA by FL as well as GA by AC. TCD had highest correlation with
value of 0.969. There was statistically significant positive correlation
between GA by TCD with GA by LMP and GA by BPD, GA by FL as
well as GA by AC. Conclusion: According to the study, TCD is the
most accurate method for determining gestational age in the third
trimester, followed by FL, and BPD is the least accurate. Additionally,
even in cases where patients are unaware of their dates, we may be
fairly positive of gestational age by combining the accuracy of TCD
(89%) and FL (79%)
