Background: Gestational age is frequently over or under estimated, as the conventional gestational estimation is based on the last menstrual period and on ultrasonography. Many people are unaware of their last menstrual period and irregular menstruation and ultrasonography is bound to have a bias, thereby posing difficulties in the estimation gestational age. Placental thickness measured at the level of umbilical cord insertion appears to be a new promising parameter for estimation of gestational age of fetus as placenta is a maternal foetal organ and its size is a reflection of the health and size of the foetus. It provides the physiological link between a pregnant woman and the fetus.Measurement of placental thickness is relatively simple and very useful. In our present study we have tried to measure Placental thickness at the level of umbilical cord and determine its relationship with gestational age of foetus in normal singleton pregnancy.
Methods: The current crossectional study was conducted at the department of radiodiagnosis, Gandhi medical college and Hamidia hospital, Bhopal from April 2012 to December 2014. This is a hospital based study with a sample size of 199 normal antenatal women. All the subjects were enrolled with detailed oral and written consents. All examinations were performed using GE logic 3 expert scanner with 3.5 MHz convex array transducer. Placental thickness in millimeters was measured at the level of insertion of the umbilical cord. Data was compiled in MS excel sheet and analyzed using online statistical calculator, chi square test and pearson correlation coefficient were applied with value of P
