What is an Interval Growth Scan?

An interval growth scan is a type of prenatal ultrasound examination performed during pregnancy to assess the growth and well-being of the fetus. It is typically performed between 28 and 40 weeks of pregnancy, and its frequency and timing depend on several factors, such as the gestational age of the fetus, maternal health, and pregnancy history.

The interval growth scan measures the size and weight of the fetus, and checks for the proper growth of the head, abdomen, and limbs. It also assesses the amount of amniotic fluid surrounding the fetus and checks the position of the placenta, which provides important information about the fetus’s health and development.

The interval growth scan can help detect potential problems, such as small-for-gestational-age (SGA) or large-for-gestational-age (LGA) fetuses, fetal distress, or problems with the placenta or amniotic fluid. Early detection of these problems can help healthcare providers make informed decisions about the best course of action for the mother and the fetus.
