Researchers at Kobe University created an artificial intelligence system that can identify a rare endocrine disease called acromegaly by examining photos of the back of the hand and a clenched fist. The AI tool is more accurate than experienced doctors and could help diagnose patients faster.

Acromegaly is a rare condition that usually appears in middle age. It's caused by excessive production of growth hormone, which leads to enlarged hands and feet, changes in facial appearance, and abnormal growth of bones and internal organs. Because the disorder develops gradually over many years, it can be difficult to recognize early. If left untreated, acromegaly can lead to serious health problems and shorten life expectancy by about 10 years.

The researchers reviewed existing AI studies and found that most systems depend on facial photos to identify disease. However, facial recognition can raise privacy concerns for patients. To address this issue, the scientists chose a different strategy.

They limited their images to the back of the hand and a clenched fist, intentionally avoiding palm images because palm line patterns are highly individual and could reveal identity. This careful approach helped recruit a large number of participants. In total, 725 patients from 15 medical institutions across Japan contributed more than 11,000 images used to train and test the AI model.

The team reported their results in the Journal of Clinical Endocrinology & Metabolism. Their AI model demonstrated very high sensitivity and specificity when identifying acromegaly from the hand images. In direct comparisons, the system even performed better than experienced endocrinologists who evaluated the same photographs.

Why It Matters

This technology could help doctors refer patients to specialists more quickly and improve access to care in underserved areas. It's an important step towards making healthcare more efficient and accessible for everyone.
