The transverse cerebellar diameter in estimating gestational age in the large for gestational age fetus

The transverse cerebellar diameter was measured in 62 nondiabetic and 30 diabetic women with large for gestational age fetuses. Using reference curves from 675 women with normal gestations between 14-42 weeks, head circumference and abdominal circumference overestimated gestational age significantly in both study groups, whereas the transverse cerebellar diameter did not.
