Title- A comparative analysis of established versus newer Standard Anatomical parameters for fetal age
determination – An Ultrasound study
Objective- The objective of the study was to determine the growth of fetus in different trimesters with the help of
fetal parameters and see the extent of disparity of individual parameters to be still acceptable for incorporation into
the composite age estimate.
Background- The anatomical plane chosen for measurement of various fetal parameters was obtained by placing
the transducer over abdomen in the midsaggital section. The fetal head was then looked for the lie of the fetus.
Then the transducer was placed in the parasaggital plane to define other fetal parts. Each examination was
performed after the routine antenatal check up by the obstetrician prior to the scan. The patients were explained
about the procedure and its purpose, prior to scanning. Patient was placed supine and the area between the pubic
symphysis and umbilicus was exposed, the ultrasound jelly was applied to the skin and transducers head. The jelly
serves to make better contact between the skin surface and the transducer, making the passage of ultrasonic waves
easier.
