Level 2 Ultrasound

Level 2 Ultrasound (Anomaly Scan / Targeted Imaging for Fetal Anomalies – TIFFA Scan)

A Level 2 Ultrasound, also known as the Anomaly Scan or TIFFA (Targeted Imaging for Fetal Anomalies) Scan, is a detailed ultrasound performed between 18 to 22 weeks of pregnancy. It is a crucial mid-pregnancy scan to check the baby’s growth, development, and any structural abnormalities.

Why is a Level 2 Scan Done?

✅ Detects Structural Abnormalities – Checks for defects in the brain, spine, heart, kidneys, limbs, and other organs.
✅ Fetal Growth & Placental Health – Ensures the baby is growing as expected and checks placenta position (low-lying placenta or placenta previa).
✅ Amniotic Fluid & Cervical Length – Assesses amniotic fluid levels and cervix length to predict preterm labor risk.
✅ Fetal Heart & Blood Flow (Doppler Study) – Screens for congenital heart defects and checks blood circulation.
✅ Facial & Limb Development – Identifies cleft lip, clubfoot, or limb deformities.
✅ Gender Determination (If Legal & Allowed in Your Country) – In some countries, gender determination is restricted by law.

When is the Level 2 Scan Done?

📌 Between 18 to 22 weeks of pregnancy (ideal at 20 weeks).

Preparation for the Scan:

🔹 No fasting required.
🔹 Drink water & keep the bladder moderately full for better imaging.
🔹 Wear comfortable, loose clothing.

Procedure:

1️⃣ A gel is applied to your abdomen.
2️⃣ A transducer (probe) is moved over the belly to capture detailed images.
3️⃣ The doctor/technician checks each organ systematically.
4️⃣ Measurements of the head, abdomen, femur (thigh bone), and other body parts are taken.
5️⃣ Amniotic fluid levels, placenta position, and blood flow are evaluated.
6️⃣ The scan takes 30-45 minutes and is painless.

What Does a Level 2 Scan Detect?

✅ Neural Tube Defects – Spina bifida, anencephaly
✅ Congenital Heart Defects – Septal defects, hypoplastic heart
✅ Limb Abnormalities – Clubfoot, missing limbs
✅ Kidney & Bladder Issues – Hydronephrosis, absent kidneys
✅ Abdominal Wall Defects – Gastroschisis, omphalocele
✅ Facial Abnormalities – Cleft lip, cleft palate
✅ Placenta Issues – Placenta previa, placental insufficiency

📌 If any abnormality is found, further tests like fetal echocardiography, amniocentesis, or genetic testing may be suggested.

Is a Level 2 Scan Safe?

✅ Yes, it is completely safe, non-invasive, and radiation-free.
✅ Essential for all pregnant women, especially those with high-risk pregnancies.
