Radiologists at the Elisabeth-TweeSteden Hospital (ETZ) in the Dutch city of Tilburg are assisted by artificial intelligence to determine whether a patient has broken something. The computer program BoneView appears to be excellent at detecting bone fractures on X-rays.

The algorithm analyzed 600 recent X-rays. During that test phase, as many as seven fractures were discovered that specialists had not noticed. “Our test showed that BoneView is able to find fractures that the specialists could not see with the naked eye,” says radiologist Erik Ranschaert. Extending the study results to an entire year, the hospital could detect 360 to 370 missed fractures per year, he adds. “That’s a significant number.”

Single tool
However, according to Ranschaert, it is too early to let the algorithm analyze X-rays on its own, without human intervention. After all, BoneView was missing three fractures that a radiologist found. The algorithm thus remains a tool. “The final assessment of the X-rays remains an important task for the specialist, who remains ultimately responsible,” it sounds.

The software assesses an X-ray in three minutes. In most cases, BoneView can say with certainty whether or not the patient has a fracture, but the outcome can also be questionable. Then the algorithm places a dotted line where it suspects a fracture and it’s up to the radiologist to cut the knot.
