A TIFFA scan, which stands for Targeted Imaging For Fetal Anomalies scan, is essentially a detailed fetal anomaly scan performed during pregnancy. It's a crucial ultrasound examination designed to detect any potential physical abnormalities or congenital conditions in the developing fetus.
Purpose of a TIFFA Scan
The primary purpose of a TIFFA scan is to thoroughly assess the baby's anatomy and development. This comprehensive ultrasound allows healthcare professionals to:
- Identify Congenital Anomalies: Detect structural abnormalities of the organs, limbs, and other body parts.
- Assess Fetal Growth: Evaluate the baby's size and growth rate to ensure healthy development.
- Evaluate Organ Function: To the degree possible, assess the function of the developing organs.
- Check Placental Position and Amniotic Fluid Levels: Ensure the placenta is properly positioned and that there is adequate amniotic fluid surrounding the baby.
- Confirm Gestational Age and Due Date: Double-check the baby's age and estimated delivery date.
- Determine the Baby's Sex: Although not the primary purpose, parents can often find out the sex of their baby during this scan.
When is a TIFFA Scan Performed?
TIFFA scans are typically performed between 18 to 22 weeks of pregnancy. This timeframe allows for the clearest visualization of the fetal anatomy, making it easier to detect any potential issues.
What Does the Scan Involve?
During the scan, a trained sonographer will use an ultrasound machine to generate images of the fetus. They will carefully examine various aspects, including:
- Brain and Spinal Cord: Checking for neural tube defects.
- Face: Examining the lips, nose, and eyes.
- Heart: Assessing the heart's structure and function.
- Lungs: Observing lung development.
- Abdomen: Examining the stomach, kidneys, bladder, and bowel.
- Limbs: Ensuring proper formation of arms, legs, hands, and feet.
- Placenta and Amniotic Fluid: Assessing their condition and position.
What Happens if an Anomaly is Detected?
If the TIFFA scan reveals any abnormalities, further investigations may be recommended. These may include:
- Repeat Ultrasound: To confirm the findings and get a clearer picture.
- Amniocentesis or Chorionic Villus Sampling (CVS): To analyze the baby's chromosomes.
- Fetal Echocardiogram: A more detailed ultrasound of the baby's heart.
- Consultation with Specialists: To discuss the findings and plan for future management.
It's important to remember that detecting an anomaly during a TIFFA scan doesn't always mean a severe condition. In many cases, the issue can be managed or corrected after birth. Early detection allows for proper planning and ensures the best possible outcome for the baby.
