Early Arthritis Diagnosis Possible With New Test
The MRI scan looks for low levels of the chemical glycosaminogycan, which helps cartilage in joints hold the water that makes it tough and elastic.
New York University researchers told the American Chemical Society conference early diagnosis could reduce the need for surgery later in life.
The Arthritis Research Campaign said the scan could help assess treatments.
The weakening and breakdown of cartilage, which cushions the moving parts of joints, is a key factor in the development of osteoarthritis, which is common in the over-40s.
Cartilage is tough and elastic because of its high water content, and existing MRI scans look for lower levels of this as a sign that the disease is developing.
The team is trying to spot the disease even earlier by looking for a substance called glycosaminogycan (GAG), which helps the cartilage hold plenty of water.
The scientists found a way to make the hydrogen atoms attached to GAG emit a signal, which can be picked up by the scanner.
"Our methods have the potential for providing early warning signs for cartilage disorders like osteoarthritis, thus potentially avoiding surgery and physical therapy later on, BBC quoted Dr Alexej Jerschow, one of the researchers, as saying.
He said that a patient given early notice of impending arthritis could take steps to protect their joints, perhaps using dietary supplements such as glucosamine and chondroitin, which may be able to slow or halt joint degeneration.
