Intrauterine growth retardation continues to be among the most commonly recognized abnormalities of the fetal condition. This is a retrospective study to determine the accuracy of ultrasound in predicting the outcomes of antenatally diagnosed IUGR in this institution. A retrospective review of ultrasound findings of patients with singleton pregnancies scanned at the Ultrasound Section of the Department of OB-GYN from January to December 2001 was done. The sensitivity, specificity, positive and negative predictive values of ultrasound diagnosis of IUGR compared with neonatal outcome were calculated using the two-tailed student t-test and chi test with a significance level of p <0.05. Validity testing showed that ultrasonography is 67.35% accurate in predicting IUGR using estimated fetal weight as a parameter. It is also 100% sensitive and 55.56% specific in detecting IUGR. The positive predictive value was 44.83% and the negative predictive value was 100%. Recommendations for increasing the sample size and uniformity of sonologist to counteract interobserver differences in skill and interpretation of ultrasound findings are suggested.
