Purpose To assess the value of fetal soft tissue volume (STV) of the upper arm in predicting small‐for‐gestational‐age (SGA) fetuses using three‐dimensional (3D) ultrasound (US). Methods We used 3D US to test the accuracy of fetal STV of the upper arm measurement in predicting SGA in a prospective cross‐sectional study. Results Fetal STV of the upper arm assessed by 3D US can differentiate SGA fetuses from appropriate‐for‐gestational‐age (AGA) fetuses. Using the 5th percentile as the cutoff, the sensitivity of fetal upper arm STV in predicting SGA fetuses was 84.1%, specificity, 93.4%, positive predictive value, 71.1%, negative predictive value, 96.8%, and overall accuracy, 91.9%. In addition, the diagnostic accuracy of fetal arm STV was better than that of the biparietal diameter, abdominal circumference, and femur length. Conclusion Fetal STV of upper arm assessment by 3D US is a novel method to predict SGA fetuses. © 2010 Wiley Periodicals, Inc. J Clin Ultrasound, 2011
