The AI revolution: for patients, promise and challenges ahead

They represent blood, and they're color-coded based on speed: turquoise and green for the fastest flow, yellow and red for the slowest. This real-time video, which can be rotated and viewed from any angle, allows doctors to spot problems like a leaky heart valve or a failing surgical repair with unprecedented speed. And artificial intelligence (AI) imaging technology made it possible. "It's quite simple, it's like a video game," said Dr. Albert Hsiao, an associate professor of radiology at the University of California, San Diego, who developed the technology while a medical resident at Stanford University. There's a lot going on behind the scenes to support this simplicity.
