The Anomaly Scan (TIFFA Scan): A Complete Guide for Expecting Parents in Pathanapuram

Introduction

Missing the 18–22 week window for the pregnancy anomaly scan is a common worry for expecting parents. Many also wonder whether they need to fast, come with a full bladder, or how long the scan takes if the baby keeps turning away. If you live in or around Pathanapuram, Punalur, or Adoor, this guide explains exactly what to expect from the TIFFA (Targeted Imaging for Fetal Anomalies) scan and how Nucleus Scans & Diagnostic Centre can support you with clear, compassionate care close to home.

Understanding the Topic

The anomaly scan, also called the TIFFA scan, is a detailed ultrasound typically performed between 18 and 22 weeks of pregnancy. It carefully evaluates the baby’s developing organs and structures, including the brain, face, spine, heart, stomach, kidneys, bladder, limbs, umbilical cord, and the placenta’s position. We also check amniotic fluid levels and, when required, measure cervical length to assess the risk of preterm birth.

Unlike early scans that mainly confirm pregnancy and dating, the anomaly scan focuses on structural development. It can detect major anomalies, identify “soft markers” that may warrant additional assessment, and help your obstetrician plan the safest pregnancy and delivery pathway. The standard exam is performed in 2D (medical diagnostic standard). While 3D/4D images can sometimes help clarify a facial or limb view, they are optional and not a substitute for the medical anomaly scan. In India, determining or disclosing the baby’s sex is illegal under PCPNDT guidelines and is not performed.

Who Is This Relevant For?

• All pregnant women, ideally at 20 weeks (acceptable range 18–22 weeks)
• Mothers with diabetes, hypertension, thyroid conditions, or on long-term medications
• Those with a previous child with anomalies, prior pregnancy losses, or IVF/ICSI conception
• Women with a family history of genetic or structural conditions
• Consanguineous marriages or advanced maternal age
• Any pregnancy where the first-trimester screening suggested higher risk

Why This Matters for Health

Early identification of structural issues allows your care team to plan timely care—ranging from specialized delivery arrangements to neonatal support and, in select cases, fetal therapy at tertiary centers. Even when everything looks normal, the scan offers reassurance during a pivotal stage of fetal development. It also flags placental position concerns (such as low-lying placenta) and can pick up signs pointing to growth or circulation issues that may need closer monitoring later.

It is important to understand the scan’s limitations. Not all anomalies can be detected, and some conditions only become apparent later in pregnancy. If any concerns arise, your obstetrician may recommend additional scans, a fetal echocardiography, or blood-based screening like non-invasive prenatal testing (NIPT). Routine maternal tests—such as complete blood count, thyroid function test (T3, T4, TSH), and diabetes HbA1c monitoring—also provide essential context for a healthy pregnancy and can be completed conveniently via Thyrocare at Nucleus Scans.

Recommended Ultrasound Scan Timeline During Pregnancy

• First trimester:
  • Dating scan (around 6–9 weeks): Confirms location of pregnancy, fetal heartbeat, and estimates due date.
  • Nuchal translucency (NT) scan (11–13+6 weeks): Measures fluid at the back of the baby’s neck as part of screening for chromosomal conditions; usually paired with blood tests per your doctor’s advice.
• Second trimester:
  • Anomaly scan/TIFFA (18–22 weeks, ideally ~20 weeks): A detailed structural assessment of the baby’s organs, placenta, and amniotic fluid. This is a key medical milestone.
• Third trimester:
  • Growth scan (28–32 weeks): Checks baby’s growth, position, placenta, and fluid.
  • Repeat growth scan and Doppler if required (32–36 weeks): Evaluates blood flow in the placenta and umbilical cord, especially if there are growth or blood pressure concerns.

These scans are simple, safe, and provide crucial reassurance. Your obstetrician will tailor the schedule if special monitoring is needed.

How to Prepare

No fasting is needed for an anomaly scan. Eat and hydrate normally. A very full bladder is not required at this stage, though a comfortably filled bladder can sometimes improve early views. Wear a two-piece outfit so your abdomen can be easily accessed. Bring previous scan reports, doctor’s notes, and any blood tests, including thyroid function test (T3, T4, TSH), complete blood count, or diabetes HbA1c reports.

If your doctor has requested additional blood tests the same day, our Thyrocare-backed testing makes it convenient. We can guide you on fasting rules for a blood sugar test, lipid profile, or other preventive annual health screening. For monsoon-related fevers, dengue and leptospirosis tests are also available via Thyrocare as advised by your clinician.

What Happens During and After the Procedure

On arrival, our team will verify your details and review previous reports. During the scan, gel is applied to your abdomen and a transducer is moved over the skin to capture images. Most anomaly scans take 30–45 minutes; they may take longer if the baby’s position limits views. Occasionally, a brief transvaginal scan is suggested to measure cervical length more accurately—this is optional and discussed with you first.

The examination is gentle and comfortable. Ultrasound uses sound waves, not radiation, and is safe when performed by trained professionals. After the scan, preliminary impressions may be shared, while the final report is carefully reviewed and signed by our lead radiologist, Dr. Namitha Shah (Ultrasound & Women’s Imaging). You will receive the report and images for discussion with your obstetrician. If any additional steps are recommended—such as a targeted cardiac scan, repeat imaging for a better view, or specific lab tests—our team will guide you clearly and calmly.

Frequently Asked Questions (FAQs)

1) When is the best time for a pregnancy anomaly scan?
The ideal time is around 20 weeks, with an acceptable window from 18 to 22 weeks. This timing provides the best views of the baby’s organs and structures. Your obstetrician may recommend earlier or later add-on scans if special monitoring is needed.

2) Is the TIFFA scan safe for me and my baby?
Yes. Ultrasound uses sound waves and does not involve radiation. When performed by trained professionals using appropriate settings, it is considered safe throughout pregnancy and is a globally accepted standard of prenatal care.

3) Do I need to fast or have a full bladder?
No fasting is required for the anomaly scan. A very full bladder is usually not necessary at this stage. Eat and drink as you normally would, and wear a comfortable two-piece outfit for convenience.

4) What if the baby does not cooperate or keeps turning away?
This is common and nothing to worry about. We may ask you to change positions, walk a little, or return after a short break. In some cases, a brief repeat scan is scheduled to complete images safely and thoroughly.

5) Will the scan detect every problem?
The anomaly scan detects many major structural issues and provides essential reassurance. However, no test can find every condition. Some issues develop later or are too subtle at this stage. If anything is unclear, your doctor may advise a focused follow-up scan or tests.

6) Is sex determination part of the anomaly scan?
No. Determining or disclosing fetal sex is illegal in India under the PCPNDT Act, and we strictly comply with all regulations. The scan focuses on your baby’s health, growth, and anatomy.

7) Can I do related blood tests on the same day?
Yes. Through our Thyrocare-supported lab services, you can complete tests like thyroid function test (T3, T4, TSH), complete blood count, diabetes HbA1c monitoring, lipid profile, and infection screens (including dengue and leptospirosis test) as advised. Call us to check sample timing and any fasting rules.

8) What happens if the report shows an abnormality?
Do not panic. Your obstetrician will guide next steps, which may include a targeted repeat scan, fetal echocardiography, or genetic counseling. Our team will coordinate timely appointments and provide clear documentation for referral if needed.

9) Are 3D/4D scans necessary?
The medical standard for anomaly assessment is a detailed 2D ultrasound. While 3D/4D ultrasound scan views can be helpful in selected situations or for keepsake images, they are not a replacement for a thorough medical evaluation. The decision depends on clinical need and your doctor’s advice.
