Abstract:
The cerebellum, the largest part of hind brain, lies in the posterior cranial fossa.In the embryo cerebellum appears at the end of the fifth week as a swelling overriding the fourth ventricle. Assessment of gestational age (G.A.) is important in the management of pregnancy.
This is descriptive, cross sectional study was carried out on ultrasound department in Omdurman maternity hospital and Bashair hospital. The study aim to assess the reliability of trans-cerebellum diameter in compare with the femur length and BPD in predicting gestational age. Fifty pregnant women presented to the Omdurman maternity hospital and Bashair hospital for routine ultrasound examination were selected and gestational age using the femur length and the BPD and Trans-cerebellum diameter was calculated.
The result of the study revealed that is there is no significant difference between gestational age obtained with femur length and BPD and thetrans-cerebellum diameter .The study recommended that the trans-cerebellum diameter can be used as routine measurement in estimation of the gestational age in the second and third trimester.
