A new form of magnetic resonance imaging (MRI) that makes cancerous tissue glow in medical images could help doctors more accurately detect and track the progression of cancer over time.
The innovation, developed by researchers at the University of Waterloo (Ontario, Canada), creates images in which cancerous tissue appears to light up compared to healthy tissue, making it easier to see. Irregular packing of cells leads to differences in the way water molecules move in cancerous tissue compared to healthy tissue. The new technology, called synthetic correlated diffusion imaging, highlights these differences by capturing, synthesizing and mixing MRI signals at different gradient pulse strengths and timings.
In the largest study of its kind, the researchers applied the technology to a cohort of 200 patients with prostate cancer. Compared to standard MRI techniques, synthetic correlated diffusion imaging was better at delineating significant cancerous tissue, making it a potentially powerful tool for doctors and radiologists.
"Our studies show this new technology has promising potential to improve cancer screening, prognosis and treatment planning," said Alexander Wong, Canada Research Chair in Artificial Intelligence and Medical Imaging and a professor of systems design engineering at Waterloo. "Prostate cancer is the second most common cancer in men worldwide and the most frequently diagnosed cancer among men in more developed countries. That's why we targeted it first in our research. We also have very promising results for breast cancer screening, detection, and treatment planning. This could be a game-changer for many kinds of cancer imaging and clinical decision support."
