RESUMO
A study carried out in two PAF hospitals radiology departments to determine the frequency of different anomalies by ultrasonographic detection. We subjected the pregnant ladies for ultrasonography who had basic screening done in obstetric department and had suspicion of some anomaly and were sent for detailed scanning. Other groups of patients were those who had bad obstetric history and sent from gynecological department for detailed scanning. About 200 patients were scanned, Out of these 134 had different anomalies and the commonest was from central nervous system with relatively more prevalent in cousin marriages. The study concluded in a small section of population showed the preponderance of neural tube defects as detected by ultrasonography but an area which was not subjected to detailed scanning was cardiac anomaly scanning due to non-availability of equipment and expertise in peripheral hospitals and may be possible in dedicated tertiary care hospitals
