A Faster Way to See a Growing Brain
Imagine a doctor looking at an MRI scan of a baby’s brain. They need to measure dozens of tiny regions to see if the brain is growing normally. Doing this by hand is slow, takes hours, and can have mistakes.
Now, imagine a tool that does this work in less than 10 minutes. It’s as accurate as an expert and can be used on both unborn babies and newborns.
That’s what a new AI tool called Multi-BOUNTI promises. It’s designed to make studying baby brain growth faster and more reliable.
A baby’s brain grows faster in the womb than at any other time in life. In just a few weeks, it doubles in size and forms complex connections.
Doctors use MRI scans to check this growth. But measuring the size of each brain region is a huge task. It’s often done by hand, which is slow and can vary from one expert to another.
This makes it hard to spot problems early. It also slows down research into how the brain develops.
Multi-BOUNTI aims to fix this. It’s a free, automated tool that can measure brain growth from MRI scans in minutes.
The Old Way vs. The New Way
The Old Way
In the past, doctors had to trace each brain region on an MRI scan by hand. This could take hours for one scan. It was also prone to human error.
The New Way
Multi-BOUNTI uses artificial intelligence (AI) to do this automatically. It learns from thousands of MRI scans to recognize and measure brain regions. The result is fast, consistent, and accurate.
But here’s the twist: This tool works for both fetuses and newborns. Most tools only work for one or the other.
Think of the brain like a house with many rooms. Each room has a different size and purpose. To understand how the house is growing, you need to measure each room regularly.
Multi-BOUNTI is like a smart floor plan tool. It uses AI to draw the rooms (brain regions) on a scan and measure their size. It does this in 3D, so it’s very precise.
The tool was trained on MRI scans from 21 to 44 weeks of gestational age. This covers the entire period from mid-pregnancy to full-term birth.
Researchers tested Multi-BOUNTI on MRI scans from the Developing Human Connectome Project. This project includes scans from 267 fetuses and 593 newborns.
The tool was compared to manual measurements by experts. It was fast (under 10 minutes per scan) and highly accurate.
The AI tool matched expert measurements very closely. It was able to create a "growth chart" for the brain, showing how each region grows week by week.
This is a big deal. Before, doctors didn’t have a standard way to measure baby brain growth. Now, they can compare a baby’s scan to a large dataset of healthy brains.
The tool also found differences between fetuses and preterm newborns. This helps researchers understand how early birth affects brain development.
But there’s a catch.
This tool is not yet ready for everyday hospital use. It’s still being tested and refined. But it’s a step in the right direction.
Experts say that tools like Multi-BOUNTI could help make baby brain scans more routine. This could lead to earlier detection of developmental issues.
If you’re a parent or caregiver, this tool is not something you can use directly. It’s for doctors and researchers.
But it could lead to better care for babies in the future. If your baby needs an MRI, this tool might help their doctor get results faster and more accurately.
This doesn’t mean this treatment is available yet.
The study was based on MRI scans from a single project. More testing is needed to see if it works just as well in other hospitals.
The tool is also not yet approved for clinical use. It’s still in the research phase.
The researchers have made the tool free and publicly available. This means other scientists can test and improve it.
Next, they plan to run more studies to see how it performs in real-world hospitals. If all goes well, it could be approved for clinical use in a few years.
For now, Multi-BOUNTI is a promising step toward faster, more reliable baby brain scans.
