A level II ultrasound, also known as a fetal anatomical survey, gives detailed information about your baby’s growth. The scan delivers a clear image of the baby's heart, stomach, brain, and kidneys. It is a painless and safe test usually done during the second trimester (18 to 22 weeks). The test can show whether the pregnant woman has multiple fetuses. It is helpful in the management of twin pregnancies and the complications associated with it.
