Growth Scan

Overview

A Growth Scan is a specialized obstetric ultrasound examination performed during pregnancy to assess the baby's growth, development, and overall well-being. The scan measures various fetal parameters, including head circumference, abdominal circumference, femur length, estimated fetal weight, amniotic fluid volume, and placental position. These measurements help determine whether the baby is growing appropriately for the stage of pregnancy.

The examination is commonly performed during the second or third trimester and is particularly important in pregnancies where there is concern about fetal growth restriction, excessive fetal growth, maternal medical conditions, or previous pregnancy complications. Growth scans help doctors monitor fetal health and make informed decisions regarding pregnancy management.

Benefits of the Test

• Monitors fetal growth and development.
• Assesses estimated fetal weight.
• Evaluates amniotic fluid levels.
• Checks placental location and health.
• Identifies growth restriction or excessive growth.
• Supports high-risk pregnancy monitoring.
• Provides reassurance about fetal well-being.
• Safe and radiation-free examination.

Why Doctors Recommend This Test

• Monitoring fetal growth during pregnancy.
• Assessment of suspected growth restriction.
• Evaluation of high-risk pregnancies.
• Maternal diabetes or hypertension.
• Previous pregnancy complications.
• Reduced fetal movements.
• Assessment of amniotic fluid abnormalities.

Preparation Before the Test

• No special preparation is usually required.
• Wear comfortable clothing.
• Carry previous pregnancy reports and scans.
• Stay hydrated unless advised otherwise.
• Inform the doctor about any pregnancy-related concerns.
• Follow instructions provided by your healthcare provider.

Who Should Take This Test?

• Pregnant women in the second or third trimester.
• Women with high-risk pregnancies.
• Patients with diabetes or hypertension during pregnancy.
• Women with previous pregnancy complications.
• Patients with suspected fetal growth abnormalities.
• Women requiring routine fetal growth assessment.
• Pregnancies needing close fetal monitoring.

Normal Reporting Time

Reports are typically available within 2 to 3 hours after completion of the examination and radiologist review.

Detailed Information

Growth Scan is an important prenatal ultrasound examination used to evaluate whether the baby is growing normally inside the womb. During the scan, several fetal measurements are taken and compared with standard growth charts to determine if fetal development is appropriate for the gestational age.

The examination assesses fetal biometry, including head circumference, biparietal diameter, abdominal circumference, and femur length. These measurements help estimate fetal weight and identify growth abnormalities such as intrauterine growth restriction (IUGR) or fetal macrosomia. The scan also evaluates amniotic fluid volume and placental health, both of which are essential for fetal well-being.

Growth scans are particularly valuable in pregnancies complicated by maternal hypertension, diabetes, twin pregnancies, previous growth-restricted babies, or suspected fetal growth problems. Early identification of growth abnormalities allows doctors to provide timely intervention and closer monitoring when necessary.

The scan is frequently recommended by obstetricians, maternal-fetal medicine specialists, and fetal medicine experts. Findings from the examination help guide pregnancy management, delivery planning, and ongoing prenatal care.

The procedure is completely safe for both mother and baby and does not involve radiation exposure. The examination usually takes between 20 and 30 minutes. Reports are generally available within 2 to 3 hours after review by an experienced radiologist.
