Summary. Calculation of the product of crown-rump length and trunk area (CRLxTA), as measured by ultrasound between 34 and 36 weeks and combined with accurate assessment of gestational age in early pregnancy, was previously shown to be highly effective in detecting the small-for-dates fetus in a largely unselected series of patients. To assess the value of this two-stage schedule in high-risk pregnancies, 202 patients with singleton pregnancies at risk of fetal growth retardation were studied. Of the 53 babies that were small-for-dates at birth, 49 (92%) were identified in advance by CRLxTA measurement. In contrast to previous findings, measurement of trunk area (TA) alone was similarly effective, identifying in advance 48 (91%) of these small-for-dates babies.
