The ability to visualize multiple gestations via sonography is a crucial aspect of prenatal care. Detecting twins or higher-order multiples during pregnancy relies on the capabilities of ultrasound technology to image the developing fetuses within the uterus. The timing of this visualization is dependent on several factors, including the resolution of the ultrasound equipment and the gestational age of the pregnancy.
Early detection of multiple pregnancies offers several advantages. It allows for appropriate medical management, which may include increased monitoring for potential complications such as preterm labor, preeclampsia, and twin-twin transfusion syndrome. Historically, the diagnosis of twins often occurred later in pregnancy, sometimes even at delivery. Modern ultrasound technology enables earlier identification, leading to improved outcomes through proactive intervention.
