An anomaly scan, also known as a level 2 ultrasound or anatomy scan, is a detailed prenatal screening performed during the second trimester of pregnancy, typically between 18 and 22 weeks. The primary purpose of this non-invasive test is to examine the physical development of the fetus and rule out structural congenital conditions.During the procedure, a sonographer applies gel to the expectant mother's abdomen and uses a transducer probe to send high-frequency sound waves into the uterus. These waves bounce back to create real-time images of the baby on a monitor.The scan evaluates several critical anatomical elements:

• Fetal Organs: It examines the structure of the brain, heart chambers, kidneys, stomach, and diaphragm.
• Spine and Limbs: It checks the alignment of the spine, the presence of all four limbs, and individual fingers and toes.
• Facial Structures: It looks at the baby's profile to rule out conditions like a cleft lip.
• Support System: It measures amniotic fluid levels, assesses the umbilical cord, and determines the position of the placenta to ensure it isn't blocking the cervix (placenta previa).
