story Medical artificial intelligence software detects aneurysms.

— facts —-

an artificial intelligence software tool found aneurysms better than physicians:

part 1:

  • computer software called artificial intelligence (AI) specializes in revealing patterns in large + complex piles of data
  • AI programs can often pick-out key issues, better than a person
  • the software is trained to sift through mountains of info — efficiently sorting data into maps of knowledge
  • so AI is especially useful in fields that process high volumes of data — like: medicine, economics, physics, engineering
  • medical researchers hope to build AI software that can diagnose patients

part 2:

  • a team at Stanford Univ. built an AI tool to help detect brain aneurysms in people
  • a brain aneurysm is a bulge in a blood vessel in the brain
  • aneurysms are dangerous because they can leak or rupture — causing bleeding into the brain
  • usually an aneurysm forms because a blood vessel is weak
  • so early detection + diagnosis are important to avoid patient death or disability
  • each year: 30,000 people in the US suffer a ruptured brain aneurysm

part 3:

  • the team’s AI software tool highlights areas of a brain scan that are likely to contain an aneurysm
  • it successfully found 6 more aneurysms than physicians did — in a set of 100 brain scans
  • to find aneurysms in a patient, physicians comb through 100s of brain images
  • aneurysms come in many sizes + shapes — and balloon-out at tricky angles
  • some appear as tiny blips on brain scan images

part 4.

  • the team taught their software by showing it 611 3D brain scans — where they outlined actual aneurysms
  • so the software learned how to identify what an aneurysm looks like in high detail
  • to use the tool, the team feeds the software a 3D brain scan made with the imaging technique called CT
  • CT stands for computed tomography angiogram — it creates a map of body tissues + blood vessels
  • then the AI software overlays the CT image with a colored highlight, wherever it finds an aneurysm
  • the team envisions an updated AI program designed to find aneurysms after they’ve burst
