Objective: 1) To detect fetal anomalies in unselected pregnant population. 2) To study the accuracy of ultrasound in the detection of fetal anomalies. Material and Methods: This study was conducted in the Department of Radiology, Ultrasound division with Toshiba Color Doppler machine with linear and convex sector probes of 3.5 MHz frequency. Study of population: – routine ultrasound examination was performed in 11 116 unselected pregnant population at first and second level obstetric unit to detect fetal anomalies. Various anomalies detected: – Anencephaly, Hydrocephalus, Holoprosencephaly, dandy-Walker malformation and variant, acrania, encephalocele, choriod plexus cyst, PUJ, Multiple cystic dysplastic kidney, Polycystic renal disease, Posterior urethral valve, Omphalocele, Esophagealduodenal atresia, Twin–Twin transfusion syndrome, Tetralogy of Fallot, Ebsteins anomaly, hypoplastic right ventricle, diaphragmatic hernia, club foot, osteogenesis imperfecta, dacrocystocele, ovarian cyst, VSD, Holt-Oram syndrome etc. Results: Over the two year study, 11 116 pregnant women were routinely scanned. We found 84 malformations of various systems, of which we detected 74 anomalies, 8 missed. In our study the ovar-all accuracy of ultrasound for the detection of fetal anomalies was approximately 91%. Conclusion: Ultrasonography has a tremendous role in the evulation of fetal anomalies. The accuracy is high. Ultrasonography is boon to obstetrics. It is safe, simple, non-invasive, easily available, acceptable to all. The Ultrasonography is the imaging modality of choice for the detection of fetal anomalies.
