Ultrasonographic Evaluation of Fetus Between 11 to 14 Weeks of Gestational Age: A Cross Section Study Conducted in a Tertiary Care Hospital, Gujarat

Background: Over the past decade, prenatal diagnosis has shifted rapidly from the second trimester into first trimester. The recent development of high frequency transvaginal ultrasound transducers has led to vastly improved ultrasound resolution and improved visualization of fetal anatomy earlier in gestation in 11 to 14 weeks of ultrasonographic scan. The early scan also provides reliable identification of chorionicity, which is the main determinant of outcome in multiple pregnancies. Objectives: This study was conducted for diagnose or suspect a wide range of structural and chromosomal anomalies of fetus; investigate the complication of early pregnancy; confirm viability; accurately date the pregnancy and diagnosis of multiple pregnancy & determination of chorionicity & amnionicity.
