Reference chart for transverse cerebellar diameter in developing fetuses according to their gestational age in Indian population

The objective of the study was to develop reference chart and to evaluate the efficacy of transverse cerebellar diameter (TCD) as one of the fetal biometric parameters used in ultrasonography to determine gestational age in the Indian population. Also, in this study we compared our findings with similar studies done on different ethnic populations to check effect of different ethnicity, environmental and nutritional factors in development of TCD.
