Anomaly / TIFFA Scan

An Anomaly Scan, also known as a TIFFA Scan (Targeted Imaging for Fetal Anomalies), is a detailed ultrasound examination generally performed between 18 and 22 weeks of pregnancy.

During this scan, the doctor carefully examines different parts of your baby's body, including the brain, face, spine, heart, abdomen, kidneys, arms and legs. The purpose is to assess how these structures are developing and look for visible structural abnormalities.

The examination also includes measurements of your baby's growth and an assessment of the placenta and amniotic fluid.

The scan is usually performed over the abdomen. The time needed can vary depending on the baby's position and how clearly different structures can be seen.

Sometimes the baby may be positioned in a way that makes certain areas difficult to examine. In such cases, the doctor may ask you to change position, take a short break or return for another examination.

Although an anomaly scan provides a detailed assessment, not every condition can be detected through ultrasound. Your doctor will explain the findings and discuss whether any additional evaluation is recommended.
