Aim: The study aimed to detect the accuracy of ultrasound examination in the diagnosis of twins pregnancy and their complications. Methods: Forty pregnant females with twins pregnancy were included in our study. Cases were recruited from the obstetrics clinic of Beni-suef University hospital. Two, three and four-dimensional Ultrasound examinations as well as Color & pulsed Doppler examination were performed to all cases. Transvaginal ultrasound examination was done in 8 cases presenting with early trimester bleeding. Results: our cases were classified into three groups according to chorionicity and amnionicity; monochorionic diamniotic (MCDA) 28 cases (70%), monochorionic monoamniotic (MCMA) in two cases (5%) and dichorionic diamniotic (DCDA) in 10 cases (25%). The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of 2DUS and both 3D/4DUS were (75%, 92%, 86%, 85%, 85%) and (81%, 96%, 93%, 88%, 90%) respectively. Conclusion: The use of 3D/4DUS in the diagnosis of twins pregnancy showed higher sensitivity and accuracy in the detection of associated congenital anomalies.
