Abstract
Transvaginal ultrasonography enables detailed visualization of the first-trimester pregnancy. Thirty-three structural anomalies have been diagnosed in the first trimester of pregnancy during a 2-year study period. An understanding of normal embryonic development is essential before attempting diagnosis in this gestational period.
