Gynecology and Obstetrics

Routine ultrasound examination is an essential part of antenatal care. With ongoing advancements, especially high-frequency transvaginal scanning has allowed ultrasound imaging resolution to enhance our recognition of normal and abnormal early pregnancy. This has played an important role in understanding human development and also has opened up unparalled possibilities to study fetal anatomy. In first trimester of pregnancy, events occur, which define the most critical and important period of human development. The indications of doing an early pregnancy scan could be to suspect miscarriage or fetal death, in vaginal bleeding, to date the pregnancy, as adjuncts to a procedure, suspecting molar pregnancy or ectopic pregnancy or multiple gestation and to localize IUD with pregnancy or to evaluate maternal pelvic masses. New nomenclature and newer management protocols can only be successful if the diagnosis is more accurate and specific.
