THE BRAIN'S BLOOD VESSELS

The brain's blood vessels are extremely important for proper brain function.

 

The brain’s small blood vessels can get injured in many ways, including:

​

​

​

When these blood vessels fail to properly heal, they can lead to:

​

​

​

EMAGIX has developed a tool for detecting injured blood vessels in the brain using MRI.

This method was validated in a series of clinical studies, demonstrating the ability to:

​

  1. Detect blood vessels that are abnormally leaky

  2. Identify patients at risk of depression and cognitive decline​

  3. Evaluate the efficacy of new drugs
