Congratulations on your pregnancy! The Tiffa (Targeted Imaging for Fetal Anomalies) or anomaly scan is typically performed between 18-24 weeks of pregnancy. This ultrasound examination helps detect any potential abnormalities in your baby's development, including structural defects, growth issues, and organ malformations. During the scan, the sonographer will carefully examine your baby's head, brain, spine, heart, limbs, and other vital organs. They will also assess the placenta and amniotic fluid levels. It is an important screening tool that can provide valuable information about your baby's well-being and help identify any potential concerns early on. If any abnormalities are detected, further diagnostic tests may be recommended to determine the best course of action for you and your baby. It is advisable to consult with your healthcare provider to schedule the Tiffa or anomaly scan at the appropriate time based on your specific circumstances.
