A tiffa scan in pregnancy is one of the most important diagnostic ultrasounds done during the second trimester. Unlike early scans that confirm pregnancy or estimate due date, this scan is focused on carefully assessing how your baby is developing inside the womb.
Most women undergo this scan between 18 and 22 weeks, often around the fifth month. By this stage, the baby's organs are formed well enough to be studied in detail. The purpose is not just to "check everything is fine," but to systematically examine each part of the baby's body and identify any structural concerns early. For many couples, this scan brings reassurance. For a few, it may raise questions that need further evaluation. Understanding the process helps reduce unnecessary anxiety.
What is Tiffa Scan?
A tiffa scan, also known as an anomaly scan, is a detailed ultrasound that evaluates fetal anatomy. It is designed to detect visible structural abnormalities and assess whether the baby's growth matches the gestational age.
Tiffa Full Form in Pregnancy
"
TIFFA stands for Targeted Imaging for Fetal Anomalies.
In simple terms, this scan "maps. the baby's body. Instead of just seeing movement or heartbeat, the doctor looks at individual organs and systems in a structured way. This includes the brain, heart, spine, kidneys, limbs, and facial features. It also checks the placenta and the fluid surrounding the baby.
In clinical settings, this scan is considered a key milestone in prenatal care because it gives a clearer picture of fetal health than earlier ultrasounds.
Tiffa Scan in Which Month is Done?
The tiffa scan is typically performed in the fifth month of pregnancy.
Recommended Time Window
- 18 to 22 weeks of pregnancy
- Most accurate results: 19-21 weeks
This timing is not random. It is chosen because the baby is developed enough for detailed imaging, but still early enough to make informed medical decisions if required.
In practice, doctors often prefer scheduling the scan around 20 weeks because:
- Organ visibility is optimal
- The baby is not too large, allowing better scanning angles
- Amniotic fluid levels support clear imaging
Tiffa Scan Weeks: Why Timing Matters
While the general recommendation is 18-22 weeks, each week within this range has its significance.
- At 18 weeks, some structures may still be small
- Around 20 weeks, most organs are clearly visible
- By 22 weeks, the window for certain medical decisions may start narrowing
If a scan is done too early, doctors may not get complete information. If done too late, follow-up options may become limited. This is why timely scheduling is important.
Why is Tiffa Scan Important.
The tiffa scan plays a crucial role in identifying structural abnormalities and ensuring the baby's development is on track.
What Doctors Evaluate in Detail
During this scan, a systematic approach is followed. Each part of the baby's body is examined carefully.
Brain and Skull
Doctors assess the structure of the brain and skull formation. Conditions such as neural tube defects or abnormal brain development may be identified at this stage.
Heart
The baby's heart is one of the most important areas examined. The sonologist looks at:
- Four chambers
- Valves
- Blood flow patterns
Some congenital heart defects can be detected during this scan.
Spine
The spine is checked for proper alignment and closure. Open spinal defects can often be identified here.
Abdomen and Organs
The stomach, kidneys, bladder, and liver are evaluated to ensure they are present and functioning normally.
Limbs
Arms, legs, fingers, and toes are checked for length, symmetry, and movement.
Face
The scan can identify conditions like cleft lip or abnormalities in facial structure.
Placenta and Amniotic Fluid
Doctors assess:
- Placenta location (important for delivery planning)
- Amniotic fluid levels (important for baby's growth and movement)
Clinical Insight from Practice
In most cases, the tiffa scan is reassuring. However, its real value lies in identifying conditions that may not show symptoms during pregnancy. Early detection allows doctors to plan monitoring, arrange specialist care, or guide parents appropriately.
It is important to understand that this scan is not meant to create fear, but to provide clarity.
Tiffa Test vs Tiffa Scan: Common Confusion
Many patients search for "tiffa test," but this usually refers to the same ultrasound scan.
- It is not a blood test
- It is an imaging-based evaluation
It is often confused with screening tests like:
- Double marker test
- Triple marker test
These blood tests assess risk for chromosomal conditions, whereas the tiffa scan examines physical structures.
Tiffa Scan Procedure: What Actually Happens
Knowing the tiffa scan procedure in advance helps reduce anxiety.
Before the Scan
You can eat normally. In most cases, no special preparation is required. Some centers may ask you to drink water, but this varies.
During the Scan
You will lie comfortably on your back. A gel is applied to your abdomen, and a handheld probe is moved across the skin. This probe sends sound waves that create images of the baby.
The sonologist takes multiple measurements and images from different angles. You may notice pauses during the scan – this is normal, as the doctor is carefully assessing each structure.
Duration
The scan usually takes 20 to 40 minutes, but it can take longer if:
- The baby is not in a good position
- More detailed evaluation is required
Is it Painful?
The scan is painless. Some mild pressure may be felt, but there is no discomfort.

Is Tiffa Scan Safe.
Yes, the tiffa scan is considered safe when performed by trained professionals.
Ultrasound uses sound waves and does not involve radiation. It has been used safely in pregnancy for many years. International guidelines, including those from the World Health Organization (WHO), support the use of ultrasound when medically indicated.
However, it is always recommended to:
- Avoid unnecessary repeated scans
- Follow your doctor's advice regarding timing
Understanding a Tiffa Scan Report in Detail
A tiffa scan report can appear technical, but it follows a structured format.
Fetal Biometry (Growth Measurements)
These measurements assess whether the baby's growth matches the gestational age.
- BPD (Biparietal Diameter): Width of the head
- HC (Head Circumference): Size of the head
- AC (Abdominal Circumference): Size of the abdomen
- FL (Femur Length): Length of the thigh bone
Doctors do not rely on a single value. Instead, they look at overall growth patterns.
Estimated Fetal Weight
This is calculated using multiple measurements. It helps assess whether the baby is growing appropriately.
Detailed Anatomy Review
Each organ system is documented. Findings may be described as:
- Normal
- Visualized
- Not clearly seen (requiring follow-up)
Placenta and Cervix
The report will mention placenta position. A low-lying placenta may require monitoring.
Cervical length is also assessed to evaluate the risk of preterm delivery.
Amniotic Fluid
Fluid levels are measured to ensure the baby has enough space and support for growth.
Common Findings and What They Mean
Some findings may sound concerning but are often harmless.
Soft Markers
Examples include:
- Echogenic focus in the heart
- Mild kidney dilation
- Small cysts in the brain
These findings:
- Are relatively common
- Often resolve on their own
- Usually do not affect the baby
Doctors interpret them in the context of other tests before making conclusions.
Structural Abnormalities
Less commonly, the scan may detect:
- Heart defects
- Spine abnormalities
- Limb differences
In such cases, further evaluation is recommended.
What Happens if the Tiffa Scan is Abnormal.
If something unusual is detected, doctors usually follow a step-by-step approach.
First, the finding is confirmed, sometimes with a repeat scan. Then, its significance is assessed. Depending on the situation, additional tests may be advised, such as fetal echocardiography or genetic testing.
Importantly, not every abnormality is serious. Some conditions require only monitoring, while others may need specialized care.
Clear counselling is an essential part of this process.
Tiffa Scan vs Other Pregnancy Scans
Understanding how this scan differs from others can help avoid confusion.
- NT Scan (11-13 weeks): Screens for chromosomal risk
- Tiffa Scan (18-22 weeks): Evaluates structural development
- Growth Scan (later pregnancy): Tracks baby's weight and growth
The tiffa scan is the most detailed structural assessment during pregnancy.
Real-Life Perspective
It is common for patients to feel anxious after reading terms in the report. For example, a finding like "echogenic intracardiac focus. often sounds serious but is usually benign.
In many cases, after proper evaluation, no treatment is required. This is why interpretation by a qualified doctor is essential.
When Should You Consult a Doctor.
You should discuss your report with your doctor if:
- Any abnormality is mentioned
- Follow-up scan is advised
- You do not understand the report
Avoid relying on internet searches alone, as they can often increase anxiety without providing context.
Limitations of Tiffa Scan
While highly useful, the scan has some limitations:
- It depends on the baby's position
- Not all conditions can be detected
- Image clarity may vary
- Some findings require follow-up

When to Consider a Consultation
If you are planning your scan or have received your tiffa scan report and feel unsure about the findings, consulting an experienced gynecologist or fetal medicine specialist can provide clarity.
A timely discussion helps you understand what is normal, what needs attention, and what steps – if any – are required next.
Conclusion: A Balanced Perspective
A tiffa scan in pregnancy is a detailed and important evaluation that helps ensure your baby's development is progressing normally. For most women, the results are reassuring. When something unexpected is found, it does not always mean a serious problem, but it does require proper medical guidance.
The best approach is to stay informed, avoid unnecessary worry, and maintain regular follow-ups.
