The author presents three hundred and ninety-five women who underwent obstetric ultrasonography between July 1992 and March 1993. The aim was to assess the accurate relationship between known menstrual age visa vis femoral length, biparietal diameter, head circumference and abdominal circumference. It was done for gestation age fourteen to forty-two weeks. Out of the 395 clients all attending ante-natal clinic at Kenyatta National Hospital, 296 were sure of their normal last menstrual period. These numbers were assessed and found statistically viable. Ultrasonography machines used were:- 1. Phillips Orion Model using 4MHz linear transducer at X-Ray Department of Kenyatta National Hospital. 2." Aloka SSD 650 using 3.5MHz linear transducer at Kenya Medical Research Institute, Headquarters, Nairobi (Clinical Department). No significant results differences were observed in patients examined at the two centres. Biparietal diameter, femoral length, head and abdominal circumferences were worked out and compared with known menstrual ages. Outliers removed, there was good correlation between known menstrual age and ultrasound measurements.
