TIFFA Scan: A Comprehensive Guide to Fetal Health Assessment During Pregnancy



In the realm of prenatal care, medical technology has made remarkable advancements to ensure the health and well-being of both expectant mothers and their unborn babies. One such significant advancement is the TIFFA scan, a crucial diagnostic tool that has revolutionized the way fetal health is monitored during pregnancy. This article will delve into the details of the TIFFA scan, its purpose, procedure, benefits, and potential risks, offering valuable insights into its importance in modern obstetric practice.

What is a TIFFA scan?

TIFFA stands for “Targeted Imaging for Fetal Anomalies,” and the TIFFA scan is a specialized ultrasound examination conducted during pregnancy. It is also known as a targeted or level II ultrasound, providing a detailed and comprehensive assessment of the fetus’s anatomy. The scan is usually performed between 18 to 22 weeks of gestation, a critical period when many fetal abnormalities can be detected.

Why is a TIFFA scan performed?

The primary purpose of a TIFFA scan is to detect any structural anomalies or abnormalities in the developing fetus. Early identification of such issues can enable timely medical interventions and treatments, which may improve the outcome for both the baby and the mother. Moreover, the TIFFA scan offers parents valuable information about the health of their unborn child, allowing them to make informed decisions and prepare for any potential challenges ahead.

How does a TIFFA scan work?

A TIFFA scan employs high-frequency sound waves to create detailed images of the fetus inside the womb. These sound waves bounce off the developing baby and the surrounding structures, producing real-time visualizations on a monitor. The images are then interpreted by a skilled sonographer or a specialized doctor to assess the baby’s growth and detect any anomalies.

The procedure of a TIFFA scan

Preparing for the scan

Before the TIFFA scan, the expectant mother may be asked to have a full bladder, which helps improve the image quality by lifting the uterus and providing better visibility. It is essential to follow any specific instructions given by the healthcare provider to ensure a successful and accurate scan.

During the scan

During the TIFFA scan, the mother will be asked to lie on an examination table, and a special gel will be applied to her abdomen. The sonographer will then use a transducer, a device that emits and receives ultrasound waves, to capture images of the fetus. The procedure is painless and typically takes around 30 to 45 minutes, depending on various factors.

After the scan

Once the TIFFA scan is complete, the sonographer will review the images and share the findings with the expectant parents. In some cases, further evaluation or additional tests may be recommended based on the results of the scan.

Benefits of a TIFFA scan

The TIFFA scan offers several advantages, including:

  1. Early detection of fetal abnormalities.
  2. Peace of mind for parents by providing a detailed assessment of the baby’s health.
  3. Better preparation for any medical or surgical interventions that may be required after birth.
  4. Improved management of high-risk pregnancies.

Risks and limitations

It is essential to note that the TIFFA scan is considered safe for both the mother and the baby. The procedure does not use ionizing radiation, making it non-invasive and low-risk. However, like any medical test, it does have certain limitations, and not all fetal abnormalities can be detected with 100% accuracy.

When to avoid a TIFFA scan

While a TIFFA scan is generally safe, there are specific situations where it might not be recommended. For instance:

  1. Low-risk pregnancies with no identified medical concerns.
  2. The mother’s health condition or certain contraindications that may pose risks during the procedure.
  3. Personal or cultural beliefs that conflict with prenatal testing.

Alternatives to a TIFFA scan

For individuals who may not opt for a TIFFA scan, there are alternative tests available, such as:

  1. Non-invasive prenatal testing (NIPT) for specific genetic conditions.
  2. Amniocentesis for genetic and chromosomal disorders.
  3. Chorionic villus sampling (CVS) to detect genetic abnormalities.

Frequently Asked Questions (FAQs)

Is the TIFFA scan painful for the mother? 

The TIFFA scan is a painless procedure that involves applying a special gel and using a transducer on the abdomen.

Can the TIFFA scan determine the baby’s gender? 

While the primary purpose of the TIFFA scan is to assess fetal anatomy, it may be possible to determine the baby’s gender during the procedure.

Are there any risks to the baby during the TIFFA scan?

 The TIFFA scan uses ultrasound waves, which are considered safe for the baby and do not pose any known risks.

What happens if an anomaly is detected during the TIFFA scan? 

If an anomaly is detected, further evaluation and additional tests may be recommended to confirm the findings and plan appropriate medical care.

Is the TIFFA scan covered by insurance?

 In many cases, health insurance plans cover the cost of a TIFFA scan when it is medically indicated. However, it is essential to check with the insurance provider for specific details.


The TIFFA scan is a valuable tool that has revolutionized prenatal care by providing detailed insights into the health and development of the fetus. By offering early detection of potential anomalies, it empowers parents and healthcare providers to make informed decisions and provide the best possible care for both the expectant mother and her baby. When considering prenatal testing options, consulting with a qualified healthcare professional can help expectant parents make the right choices for their unique situation.
