Estimation of Gestational Age in Pregnant Women Using Trans Cerebellar Diameter by Ultrasonography

Abstract

This adescreptivecrossectional study which was aimed to know the gestational age using cerebellar diameter in Khartoum state . The study was done in alshiakhalifadul delivery hospital and tayba hospital, , at duration from September -to December, 2016. About 50 patients were randomly dy selected, aged from 18 years and above. Trans- abdominal ultrasound scanning by 3.5 MHz probes was performed. The results of this thesis states that the cerebelar diameters mean values were (3.19) cm. The study also concludes that, there statistically, significantly (Sig. = 0.000) strong positive relation (0.86) between (gestational age using last menstrual period) and cerebellar diameter, and hence the gestational age is 6.169±0.533 week increases per a cm in cerebellar diameter, showing 0.74% variation in the gestational age, can be explained by the cerebellar diameter. While there is statistically, significantly (Sig. = 0.000) strong positive relation (0.92) between (gestational age using biperietal diameter) and cerebellar diameter, and hence the gestational age is 6.605±0.399 week increases per a cm in cerebellar diameter, showing 0.85% variation in the gestational age, can be explained by the cerebellar diameter.
