“…2 Therefore, TCD/AC ratio has the advantage of being not only a relatively good predictor of IUGR but also a gestational age independent parameter. 7 Literature suggests TCD/AC ratio 2 SD above the mean is a sensitive predictor of IUGR. 3 The TCD/AC ratio was found to be gestational age independent in our study between 18 and 34 weeks of gestation and the population specific TCD/AC ratio (mean +/-SD) was 13.56 with standard deviation of 1.21 for normal fetal growth.…”

“…5 The transverse cerebellar diameter (TCD) is wellestablished in the ultrasound literature as a reliable parameter for estimating gestational age. 7 Measurements of fetal TCD have been shown to correlate with gestational age. The TCD/AC ratio is a constant between 14 and 42 weeks and, therefore is a gestational age independent factor to assess the fetal growth.…”

Objective To derive population specific transverse cerebellar diameter/abdominal circumference ratio (TCD/AC ratio) for the assessment of normal fetal growth. Materials and methods A one-year prospective observational study conducted at the KLE University's teaching hospital, Belgaum. The TCD/AC ratio was calculated for 434 obstetric patients, who met the inclusion criteria and the arithmetic mean and 1 standard deviation (SD) was calculated for the population studied. Results Within the study population, the TCD/AC ratio assessed for normal fetal growth with gestational age ranging from 18 to 34 weeks was found to be a constant with a mean of 13.56 +/− 1.21(1 SD). Conclusion A normal standard value to assess normal fetal growth is required for a given set of population in order to be compared with those fetuses with intrauterine growth restriction (IUGR). The TCD/AC value in our study remained a constant between gestational ages ranging from 18 to 34 weeks with a mean of 13.56 +/− 1.21.

Background: Intrauterine growth restriction accounts for a significant increase in perinatal mortality rate as well as immediate neonatal morbidity and continuing long term disability in some of the survivors. A different clinical problem develops in infants of same weight but different gestational age therefore identification of high risk newborns based on gestational age and weight. Hence without an accurate knowledge of gestational age, the clinician is significant hampered in an attempt to differentiate truly growth restricted fetus from a patient with incorrect gestational parameters. TCD is emerging as a new sonografic parameter and least affected by fetal growth restriction while liver is most affected organ.Methods: The patients were sonographically examined for TCD/AC ratio. The best cut-off value of TCD/AC ratio in predicting IUGR was determined by a receiver operating characteristic (ROC) curve. The fetus with a TCD/AC ratio greater than the cut-off value would be antenatally diagnosed as IUGR for every gestational week. Standard definition of IUGR was a low birth weight, less than the 10th percentile.Results: Eighty pregnancies with suspected IUGR were analyzed. The prevalence of IUGR among the study group was 51.5%. The best cut-off value of the TCD/AC ratio for predicting IUGR was 15.87%, giving the sensitivity, specificity, positive predictive value and negative predictive value of 81.25%, 62.25%, 89.65%, and 45.45%, respectively.Conclusions: The sonographic fetal TCD/AC ratio as a gestational age-independent, useful, feasible and sensitive method for antenatal diagnosis of IUGR, especially in pregnancy with uncertain gestational age. Routine TCD/AC ratio should be performed to diagnose IUGR.

“…4 Transcerebellar diameter (TCD) is one such foetal parameter that has remained consistently superior in predicting GA and foetal growth in both singleton and twin gestations. [5][6][7] It is therefore an organ that can provide information on the prediction of gestational age during the entire pregnancy. Although there are ultrasound studies on the correlation between the Transverse cerebellar diameter (TCD) in foetuses and gestational age, most studies address the third trimester of pregnancy.…”

“…Although there are ultrasound studies on the correlation between the Transverse cerebellar diameter (TCD) in foetuses and gestational age, most studies address the third trimester of pregnancy. 5,[8][9][10][11] It is therefore important to study the correlation between foetal TCD and pregnancy age, addressing early and late gestation periods. So, this study was planned to evaluate the role of foetal transcerebellar diameter in predicting gestational age.…”
