Heart scans using MRI give doctors a clear look at the heart's structure. This helps in spotting heart problems early. But, making these scans work well with computers needs lots of labeled data. Labeling data is a big job. It takes time and effort. A new method called PDFMSeg changes this. It uses a small amount of labeled data and a lot of unlabeled data. This mak...
4D flow MRI is like a superhero in the world of heart imaging. It's a special kind of scan that shows how blood moves through the heart and blood vessels. This isn't just any old scan. It gives doctors important info about how blood flows, which can help spot heart problems. But there are some issues. The scans can take a long time. Also, the images might not be as ...
The lumbosacral plexus is a crucial network of nerves that controls movement and sensation in the lower body. It can get damaged due to various reasons like injuries, diabetes, or infections. When this happens, people might feel constant pain, tingling, or even weakness. Doctors usually figure out what's wrong by talking to the patient, doing a physical check-up, an...
President Donald Trump recently shared that he had an MRI scan during his physical check-up. He described the scan as "very standard, " but what does that really mean? Trump, now 79, had this scan at Walter Reed Medical Center on October 10. However, neither he nor the White House has specified which part of his body was examined.

The focus was on two things: when athletes can safely go back to playing sports and if they are more likely to get hurt afterward. The study involved 30 teens, mostly girls, around 16 years old. They had MRIs of their neck muscles right after a concussion. Then, they had another MRI after they ...

Scientists have been trying to understand what happens in the brain of someone with schizophrenia. They think it might be about how different parts of the brain talk to each other. Recently, researchers did a study. They used a special kind of brain scan called fM...
MRI is a big deal in medicine. It's safe, detailed, and great at looking at soft tissues. Over 100 million scans happen every year. Now, scientists are making tiny sensors for MRI to detect brain chemicals. These sensors use special nanoparticles and proteins. They can pick up on things like dopamine and calcium, which are important for brain function. But there's a...
Working in high altitudes is common for many people, especially those in the aerospace industry. But what does this do to the brain? A study looked at 19 people who often work in altitude chambers and compared them to 28 healthy individuals. First, let's talk about the brain scans. Both groups had some white matter hyperintensities (WMH), which are bright spots on M...
