Introduction to Cranial Ultrasound
Cranial ultrasound is a safe and painless test that uses sound waves to create pictures of the brain. Doctors often call it a brain ultrasound or head ultrasound. This test is most common in babies, but sometimes adults need it too. Because it is non-invasive brain imaging, there is no need for surgery or needles. Many hospitals and clinics offer cranial ultrasound, making it easy to access.
What Is a Cranial Ultrasound?
A cranial ultrasound is a special scan that looks at the brain and its structures. It uses high-frequency sound waves, which bounce off the brain and create images on a screen. Unlike X-rays, it does not use radiation. For this reason, it is very safe, especially for newborns and infants. Doctors may also call this test neurosonography.
When and Why Is Cranial Ultrasound Used?
Doctors use cranial ultrasound for several reasons. Most often, it helps check the brains of premature babies. However, it can also help find problems in older children and adults. Some common reasons include:
Because it is quick and safe, doctors often choose cranial ultrasound as the first test for brain concerns in babies.
How Is the Procedure Performed?
During a cranial ultrasound, a trained technician or doctor uses a small device called a probe. First, they place a special gel on the baby’s head. Then, they move the probe gently over soft spots on the skull, called fontanelles. These soft spots allow the sound waves to reach the brain. The whole test usually takes less than 30 minutes. For older children or adults, doctors may use other soft areas or special techniques.
Who Needs a Cranial Ultrasound?
Most often, newborns and premature babies need this test. However, sometimes older children or adults may need it if doctors suspect certain brain problems. Some groups who may need a cranial ultrasound include:
Doctors decide if this test is right based on symptoms and medical history.
What to Expect: Before, During, and After the Test
Before the Test
Usually, no special preparation is needed. Babies can eat and drink as normal. If your child is older, follow any instructions from your doctor.
During the Test
During the scan, your baby will lie on a bed or in your arms. The technician will apply gel and move the probe gently. Most babies do not feel any pain. The test is quiet and does not take long. For older children, the process is similar.
After the Test
After the scan, the gel is wiped off. You can go home right away. The doctor will review the images and discuss the results with you.
