MR and CT Scans for Kids Needing Heart Surgery

Having an MR or CT can be a scary experience, especially when you’re little. Here’s how the staff at UVA help keep kids feel safe during the whole process.




Radiology: One Piece of the Puzzle

The University of Virginia Health System is one of two hospitals in Virginia that performs heart surgery in children, technically known as pediatric cardiothoracic surgery. For this complicated surgery, UVA has a multidisciplinary team made up of pediatric cardiologists, thoracic surgeons, radiologists, trainees and fellows in pediatric cardiology, NICU attendings, pediatric ICU attendings, managers, social workers, and nurses. Each Wednesday, the whole team meets to decide what treatment is best for each child.

Radiology plays an important part in the process. MR and CT scans give the surgeons information that tells them where to cut, what they will find, and what they need to do about the problem. But for kids, getting an MR or CT scan can be really scary. The newness of the big equipment, strange noises, and busy strangers in scrubs and white coats makes many children nervous.

So what happens when your child comes for an MRI or CT of the heart? What do the different scans mean? How will the staff at UVA keep your child safe and comfortable?


MRI of the Heart

MRI stands for Magnetic Resonance Imaging. It takes approximately one hour to complete. It tells the doctor about how the heart is functioning. For example, an MRI can tell the doctor how much blood is going through a certain vessel. MRI is also good at differentiating between normal and abnormal tissues. This is all important information for the doctor to have as he decides which surgery he needs to perform and, perhaps more importantly, when to perform it.

Though an MRI exam is long, the benefit is that it doesn’t use any radiation. However, because it is long, your child might need sedation. Dr. Patrick Norton explains, “They can’t sit still. It’s a contained space and it’s difficult for them.” Working with the MRI team, children at UVA as young as eight years old have successfully completed an exam without sedation. If a child is able to stay still, they can watch movies during the exam using a special pair of glasses that reflect the movie from the wall behind them. As a parent, you will work with the MRI team to determine what is best for your child.


CT of the Heart

CT stands for Computed Tomography. CT shows the doctor a lot about the structure of the heart. It shows the anatomy—what the vessels are and how they’re connected. The scan itself is very fast, sometimes only 50 milliseconds.

CT does require radiation, which is concerning to most parents. However, our radiologists have the best and latest equipment and our technicians are highly skilled at positioning children at just the right angle to get the images they need without exposing them to unnecessary radiation. “We give them a little radiation, but with the radiation protocols we have here, it’s very, very low,” said Dr. Klaus Hagspiel. We call this “imaging gently,” meaning that our radiologists use the lowest possible dose of radiation for children since their bodies are more fragile than adults.


Coming Alongside Your Family

We want your child to have the best imaging experience possible. In many cases, families will work with a child life specialist who can help a child prepare for the unknown or scary experiences they are about to face. From deciding what kind of imaging your child needs to helping your child through the exam, UVA is with you for every step.

    I am trying to raise money for surgery of Sawyer and Maya.

    Sawyer was born with a severe urological defect and his first surgery was not successful. One of caregivers is with Sawyer now in the hospital as he prepares for surgery in the coming days.

    Maya needs to gain weight and strength before she can have her needed heart surgery. One of caregivers is with her now at her home orphanage giving her the one-on-one care she needs at this time.

    Together, these surgeries will cost an estimated $35,000

    Money from every shirt will go to charity!

    Thank you
