What is it about?
In this research, a computer program has been created using a type of artificial intelligence called neural networks. This program can look at micro-magnetic resonance images of mouse brains and find blood vessels accurately and quickly. To teach such kind of programs, scientists usually need a lot of labeled data, but this new method works well even with a small amount of labeled data (only 8 sets of images in this case).

Why is it important?
Scientists use special techniques such as micro-magnetic resonance to look at blood vessels in mice to study diseases like Alzheimer's and understand how tumors grow and blood vessels form. This process usually takes a long time because they have to go through a lot of data manually - days to weeks of work.
Perspectives
The cool thing about this program is that it's free for anyone to use (open-source) and it's really good at finding blood vessels in mouse brains. We have tested it and found that it works much better and faster than other methods currently used in research. This means other scientists can study diseases more efficiently and learn more about how our bodies work.
