Assessment of Transcerebellar Diameter Accuracy in Detection of Gestational Age in Third Trimester in Cases of Intrauterine Growth Restriction

Utilization of third-trimester fetal transcerebellar diameter measurement for gestational age estimation: a comparative study using Bland-Altman analysis

“…18 A recent case-control study from Egypt conducted in 2021 analyzed 52 women at 27 and 37 weeks of gestation and found that TCD was a more accurate predictor of GA in the third trimester of pregnancy than other biometric measurements (BPD, AC, and FL). 19 An earlier similar study of 60 women concluded that TCD is the most accurate biometric measurement in both uncomplicated and complicated pregnancies. 20 This conclusion regarding the accuracy of TCD at estimating GA in the third trimester of pregnancy is further supported by findings from a study conducted in Nepal that found TCD ( r 2 =0.989; P <.001) to have a higher predictive value than that estimated using BPD ( r 2 =0.929; P <.01), HC ( r 2 =0.964; P <.01), AC ( r 2 =0.931; P <.01), and FL ( r 2 =0.966; P <.01).…”
