To determine the mean difference of Trans cerebellar diameter between normal and growth restricted fetuses as a useful indicator of growth retardation. STUDY DESIGN: Cross sectional study STUDY PLACE AND DURATION: Department of Obstetrics & Gynaecology in collaboration of Department of Radiology, Sir Syed Hospital Karachi, a private tertiary care center. Over six months from 15th June 2016 to 15th December 2016. PATIENTS AND METHODS: Total 120 pregnant women were recruited in the study referred for ultrasound scan between 28-40 weeks of gestationduring the antenatal period (60 normal fetuses and 60 growth restricted fetuses) were included. All the observations included maternal age, parity, history of any medical disorder, gestational age, last menstrual period, ultrasonographic findings (i.e. Normal growth or IUGR) and transcerebellar diameter were recorded on proforma. SPSS version 20.0 was used for data analysis. All continuous response variables like maternal age, gestational age, parity and transcerebellar diameter were presented as Mean±SD. Unpaired T-test wasapplied to see mean difference of maternal age, parity, gestational age, transcerebellar diameter between normal and growth restricted fetuses. RESULTS: Overall mean maternal age was 28.61±4.72 years and mean gestational age was 33.8±2.93 weeks. Mean transcerebeller diameter of fetus by scan of Normal group was 34.40±3.70cm and 32.93±2.47 cm of IUGR group (p=0.012). In the gestational age 37-40 weeks, mean TCD 36.11±1.537 of IUGR group was less than 38.93±2.086 of normal growing fetus group (p=0.001). Pearson's correlation (r=0.892) between TCD and actual gestational age. The correlation between gestational age and TCD in normal growth fetus was r = 0.876 and in IUGR group was r = 0.901. CONCLUSION: Measurement of TCD with expert hands is a useful indicator of growth retardation with regards to strong correlation between TCD & GA and mean difference of TCD of normal growth versus intrauterine growth restricted fetuses, particularly in gestational age group 37-40 weeks. KEYWORDS: Transcellebral diameter, growth retardation, gestational age, biometric measurement,
