This study evaluates the relationship of fetal transverse body diameter and biparietal diameter in the diagnosis of intrauterine growth retardation (IUGR). Criteria were formulated which result in 68 per cent sensitivity and 69 per cent specificity for diagnosing IUGR. The sensitivity is comparable to that achieved with other sonographic modalities, and there are important advantages as well. This method does not depend on accurate identification of the last menstrual period, and does not require serial studies. The anatomy for the necessary measurements is readily obtained and reproducible. Subtraction is the only calculation involved. Determination of the relationship of fetal transverse body diameter and biparietal diameter is recommended as a simple screening test for IUGR.
