Abstract :

Accurate knowledge of foetal gestational age is important as it helps the pregnant women, her family; the obstetricians and the radiologists in the planning of pregnancy in the prediction of the maturity and expected date of delivery and in the detection of growth retardation of foetus and congenital anomalies e.g Hydrocephalus, Spina bifida , Anencephaly etc. The advent of ultrasound method for imaging of foetus and its environment which began first with bistable static images and has now evolved to its current status of a very high resolution dynamic imaging has had a oad encompassing impact upon the very essence of obstetric care. Foetal ultrasonography has beenone of the fastest developing fields in imaging of foetus.The ability to examine the foetus and to detect foetal growth, foetal gestational age and any other foetal anomalies has dramatically changed the diagnosis and practice of Obstetrics. Hence to determine the correct foetal geststional age various sonographic parameters are used. AIMS AND OBJECTIVES-To determine the gestational age using the biparietal diameter , femur length from 28- 40 weeks of pregnancy alongwith foetal weight. In the present study data was compared to standards through their means and standard derivations to find out the prediction error in population. MATERIAL AND METHOD- 500 normal pregnant women were observed in radiodiagnosis department of jnana Hospital, Ajmer . Patient of 2^nd and 3^rd trimester were considered and ultrasonographic measurements with consent form were recorded.

RESULT-The range of variation of observed value of Biparietal Diameter , Femur length of foetus with+2SDwere taken to eradicate error.CONCLUSIONThe meanBiparietal Diameter increased from 73.11 mm at 28 weeks to 73.11 mm at 40 weeks while the femur length comparatively increased from 28 to 40 weeks but at a lower variations from 51.75 to 75.78
