NUH develops AI tool to accelerate lumbar spinal stenosis diagnosis

The tech has been trialled in over 50 patients since June.

The National University Hospital (NUH) has developed Spine AI, an artificial intelligence (AI) tool to reduce the time required for radiologists to interpret MRI scans of lumbar spinal stenosis.

The deep learning tool has been trialled in over 50 patients since June, detecting the area where the narrowing of the spinal canal occurs and categorising the severity of stenosis.

Previously, radiologists had to manually evaluate each of the five spinal segments and their five potential stenosis sites, requiring analysis of up to 25 regions per patient.

According to Dr Andrew Makmur, National University Health System’s (NUHS) group chief technology officer, creating detailed reports on stenosis can be labour-intensive and repetitive.

“With Singapore’s ageing population and an expected increase in imaging volume, there is great potential for Spine AI to augment radiologists’ efficiency and allow them to focus on more complex cases,” Makmur said.

Meanwhile, the AI tool was designed in collaboration with a team from the National University of Singapore’s School of Computing (NUS Computing) and the National University Spine Institute.

Reaching the people who run Asia's businesses is harder than it used to be.

Inboxes are crowded. Attention is short. The executives you most want to reach — the founders, CFOs, and operators who actually move budgets — are the hardest to find through the usual channels. If you're building a company, a category, or a reputation, you already know this.

We've spent twenty years building the room they read. Singapore Business Review is where senior decision makers in Singapore and across Southeast Asia come for business coverage they can't get elsewhere — in print, online, and in person at the summits and roundtables we host across seven markets.

If you have something these readers should know about — a point of view worth publishing, a product worth their attention, an event worth their time — we'd like to hear what you're trying to do.
