Role of Sonological Fetal Cerebellar Measurement in Gestational Age Determination

obstetric sonography plays, an important role in accurate determination of intrauterine gestational age. By determining accurate gestational age we can anticipate normal spontaneous delivery or to plan elective delivery with in time frame of term pregnancy. It is non invasive, non-ionizing in nature, easy availability and cost effectiveness leading to wider acceptability. USG is safer for the patient, fetus, and sinologist. Measuring transverse cerebellar diameter is to validate it as an additional morphological measurement of fetal growth with less variability.
