Multiplying the diagnostic capabilities of healthcare with the power of AI is changing the landscape of medical imaging. A recent case in Oxford demonstrates the potential for AI to identify diseases beyond the primary reasons for medical scans.
Will Studholme
Will Studholme, a 58-year-old man from Oxford, recently visited the NHS with gastrointestinal symptoms. During his visit, he underwent an abdominal CT scan for food poisoning. Unexpectedly, AI analysis of the scan revealed a collapsed vertebra, an early sign of osteoporosis.
“It was a huge surprise,” says Studholme, adding, “I feel very lucky that the AI technology caught it.” His case highlights the potential of AI in medical imaging, particularly in opportunistic screening.

Traditionally, radiologists might incidentally note something unexpected on a scan. However, the systematic use of AI to sift through scans for telltale signs of common but undiagnosed diseases marks a new era in medical diagnostics.
Perry Pickhardt, a professor at the University of Wisconsin-Madison, explains, “Opportunistic screening involves using AI to identify risks of diseases like osteoporosis during scans ordered for other conditions. It’s just beginning to be utilized clinically.”
This approach leverages the vast data from imaging studies, which doctors might otherwise overlook. AI can analyzegetImage the scans for subtle clues, improving disease detection without increasing the number of scans.
Challenges and Considerations
While AI offers significant potential, there are challenges to its widespread adoption. One concern is the additional demand it can place on healthcare systems.
Sebastien Ourselin, a professor at King’s College London, notes, “Increased identification of potential health issues can strain healthcare resources, demanding more confirmative tests and subsequent treatment.”
Furthermore, the accuracy of AI systems is crucial. If AI is too sensitive, it can lead to unnecessary testing. Ensuring the reliability of these systems is paramount.
Benefits and Real-World Impacts
The benefits of AI in opportunistic screening are substantial. It can help identify disease earlier, when intervention is most effective. For osteoporosis, early detection can prevent fractures and improve quality of life.
Kassim Javaid, a professor at the University of Oxford, spearheaded the introduction of an AI system for osteoporosis detection. At Oxford NHS hospitals, the system identified up to six times more patients with vertebral fractures than average.
“The AI allows us to catch cases we might otherwise miss, which is especially important given the rising costs of osteoporosis management,” says Prof. Javaid.
Future Prospects
The future of AI in healthcare looks promising, with ongoing trials at several hospitals. Nanox.AI, the company behind the osteoporosis detection system, aims to expand its services to other conditions like heart disease and fatty liver disease.
Prof. Ourselin suggests, “As AI technology advances, it promises to reshape the landscape of medical imaging, improving accuracy and efficiency of disease detection.”
However, successful implementation requires addressing ethical considerations, ensuring data privacy and security, and developing robust AI models.
Will Studholme’s story underscores the transformative impact of AI in healthcare. “I used to think osteoporosis was just an old person’s problem, but now I know I can take preventive steps,” he says. His experience highlights the promise of AI to improve patient outcomes and healthcare efficiency.
As AI continues to evolve, the ability to identify and treat diseases early presents a significant advantage. With careful development and application, AI has the
