A Targeted Imaging for Fetal Anomalies (TIFFA) scan, also known as a fetal anomaly scan or level II ultrasound, is a comprehensive prenatal screening test used to assess the development and health of a fetus in the womb. It is typically performed between 18 and 22 weeks of pregnancy and is considered an important part of routine prenatal care.During a TIFFA scan, a specially trained sonographer uses high-frequency sound waves to create detailed images of the fetus and the mother's reproductive organs. The scan evaluates various aspects of fetal anatomy, including the brain, spine, heart, limbs, and abdominal organs, to detect any structural abnormalities or developmental issues.
