Ultrasonographic Estimation of Fetal Gestational Age Using Foot Length as a Parameter

Appropriate assessment of gestational age is paramount in obstetric care for making appropriate management decisions. Numerous equations regarding the relationship between fetal biometric parameters and gestational age have been described. This study has been conducted to assess the reliability of foot length as a new parameter. Ultrasonographic measurement of Foot Length was done without prior knowledge of gestational age. Then the gestational age was confirmed by an early abdominal ultrasound by biparietal diameter, femur length and abdominal circumference followed by correlation of foot length with gestational age. Fetal foot length showed good correlation with gestational age with correlation coefficient 0.960 with p
