Artificial Intelligence May Help Reduce Dosage of Gadolinium in MRIs, Researchers Suggest

There’s been concern recently about the accumulation of gadolinium in the brains of people who’ve had MRIs. Gadolinium is the dye that’s used to provide the “contrast” that can highlight lesions in the brain that might not otherwise be seen. This research suggests that by using artificial intelligence techniques to tweak MRI images, it may be possible to reduce the amount of contrast agent to only 10 percent of what’s currently used and still highlight those lesions.

Artificial intelligence can help reduce the amount of gadolinium needed as a contrast agent in MRI (magnetic resonance imaging) scans, preventing the agent’s potential toxicity when accumulated in body tissue, including the brain and bones, each time it is used, researchers suggest.

The finding is of particular importance for patients
