Anamoly Scan or TIFA Scan
An anomaly scan, also known as a mid-pregnancy ultrasound or a level 2 ultrasound, is a medical imaging procedure performed during the second trimester of pregnancy. The main purpose of the anomaly scan is to assess the development and well-being of the fetus, as well as to detect any structural abnormalities or anomalies. This scan is typically conducted between the 18th and 22nd weeks of gestation.
Here are the key aspects of an anomaly scan:
1. Timing:
Anomaly scans are usually performed in the second trimester, around 18 to 22 weeks of pregnancy. This timing allows for a detailed examination of the fetus's anatomy as many of the major organs and structures are developed by this stage.
2. Procedure:
The scan is typically conducted using an ultrasound machine. A gel is applied to the mother's abdomen to facilitate the transmission of sound waves, and a transducer is moved over the belly to produce images of the fetus.
3. Purpose:
The primary purpose of the anomaly scan is to check for any structural abnormalities in the developing fetus. It involves a detailed examination of various organs and structures, including the brain, spine, heart, kidneys, limbs, and other major organs. The sonographer will assess the size, shape, and function of these structures to ensure normal development.
4. Detection of Anomalies:
The scan is particularly effective in identifying conditions such as neural tube defects, heart abnormalities, limb defects, and other congenital anomalies. It can also help confirm the gestational age and the number of fetuses in the womb.
5.Risks:
Anomaly scans are considered safe and non-invasive. They do not pose any known risks to the mother or the fetus.
6. Follow-up:
Depending on the findings of the anomaly scan, further diagnostic tests or consultations with specialists may be recommended.
It's important to note that while an anomaly scan is highly valuable in detecting many structural abnormalities, it may not identify all potential issues. In some cases, additional tests such as amniocentesis or genetic counseling may be recommended for a more comprehensive assessment of the fetus's health. The decision to undergo an anomaly scan and any subsequent procedures is a personal one and should be made in consultation with healthcare professionals.
