Reliability of two dimensions measurement of fetal thalamus as fetal growth parameter, using ultrasound of fetal brain

Abstract

Introduction: The ultrasound is considered very important part to evaluate and measure the fetal growth and fetal biometry. It is important in all pregnancies to measure fetal biometry and gestational age, biparietal diameter (BPD) and femur length (FL) is precise fetal biometrics measurements commonly doing in 2^nd and 3^rd trimester. Correct age of fetus is essential for suitable antennal attention, the aim of study is to show the reliability of summation 2-dimension thalamic size for estimation the fetus’s age by using US and compare it with other tools of fetal age measurements like BPD and FL and LMP.

Method: This is retrospective study conducted at Al Zahraa teaching maternity and pediatrics hospital at Al-najaf /Iraq, from period between march 2018-september 2019, using GE S6 Ultrasound machine. Antenatal us examination done for 99 uncomplicated pregnant women during their routine antenatal visit.

Results: A random sample  of 99 pregnant female from different trimesters of pregnancy that included in current study, there is no differences and strong positive correlation between ages of fetuses measured by summation of  2 dimension fetal thalamus and  fetal age measured by biparietal diameter (BPD), femur length (FL) and age measured by last menstrual cycle (LMP), P-value<0.05, also there is strong positive correlation between 2 dimension fetal thalamus ( height to width) and ages of fetuses measured by summation of 2 dimension of fetal thalamus.

Conclusion: we can use summation of 2-dimension fetal thalamus to detect the fetal age as a growth parameter.
