Anomaly scan
Anomaly Scan
An Anomaly Scan (pronounced: /əˈnɒməli skæn/), also known as a Mid-pregnancy scan or Level II ultrasound, is a detailed ultrasound examination of the fetal anatomy, typically performed between the 18th and 21st weeks of pregnancy. The primary purpose of this scan is to check for structural abnormalities in the fetus.
Etymology
The term "Anomaly Scan" is derived from the Greek word 'anomalos' meaning irregular, and the Latin word 'scannen' meaning to examine closely.
Procedure
During an Anomaly Scan, the sonographer examines the fetus's body in detail to ensure that all organs and physical features are developing normally. This includes the brain, heart, spine, lungs, kidneys, and limbs. The sonographer also checks the position of the placenta, the amount of amniotic fluid, and measures the fetus's size to ensure it is growing at the expected rate.
