Currently, the majority of high-level care facilities containing Neonatal Intensive Care Units (NICUs) also possess MRI scanners suitable for studying neonates. Increased utilization of these scanners has demonstrated that image acquisition is typically well tolerated by even the youngest and smallest patients. Additionally, scans can be performed successfully without the use of sedating medications, eliminating the risk associated with this procedure. 

Education 

An MRI (Magnetic Resonance Imaging) is a safe and detailed scan that takes pictures of the inside of the body. It helps doctors learn more about how your baby’s is developing and if there are any areas of concern. 

Unlike X-rays, an MRI does not use radiation; instead, it uses magnets and radio waves to take pictures, making it very safe, even for small and premature babies. 

Doctors may recommend an MRI if they want a clearer or more detailed look at your baby’s brain, spine, or other parts of the body. Common reasons include: 

• Your baby was born very early (especially before 30 weeks) 

• There were complications during pregnancy or birth 

• Earlier tests (like an ultrasound) showed changes in the brain 

• To check brain development before going home 

• To look for causes of seizures or other neurological signs 

• For consultation with brain surgeons and other specialists to decide about further management particularly of hydrocephalus 

What Happens During an MRI? 

• Your baby might need to stop feeding for a short time before the MRI. A nurse or doctor will let you know what to do. 

• Doctors often use the MRI scan using the “Fast, Feed and Wrap” technique. This technique takes advantage of the fact that most babies will go to sleep after a good feed; this allows the scan to be completed without the need for a general anaesthetic. 

• The MRI machine looks like a big tunnel. Your baby will be placed on a small bed that slides inside. 

• The machine makes loud tapping and buzzing sounds, but special ear protection will help keep your baby comfortable. 

• The MRI takes about 30 to 60 minutes.  

Once the MRI is done, doctors will look at the pictures and talk to you about what they find. If treatment is needed, they will explain the next steps to help your baby. 

Empowerment 

It can be scary when your baby needs medical tests, but remember, you are not alone. The hospital team is there to care for your baby and support you. Ask questions, take deep breaths, and know that this test is helping doctors find the best way to care for your little one. 

Your love and support are the most important things your baby needs during this time.
