Biometric diagnosis of intrauterine growth retardation

The history of the use of ultrasound for the detection of abnormal fetal growth is briefly reviewed. The problems associated with the two most commonly used parameters (biparietal diameter and abdominal circumference) are briefly reviewed. These problems are often compounded by uncertainty surrounding the gestational age. The many other parameters that have been used to assess fetal growth are briefly reviewed. A prospective study utilized two ultrasound examinations: the first at 16-20 weeks predicted the correct estimated date of confinement and the second at 32-34 weeks reliably demonstrated intrauterine growth retardation. The need for further clinical trials is stressed.
