Pioneering blood test which uses AI to quickly scan for brain tumours is up to 90% accurate

A pioneering blood test which uses artificial intelligence (AI) to spot signs of brain tumours could be used by the NHS. Scientists hope the diagnostic aid could be rolled out within 18 months, following a promising trial of the test. The AI-based test was able to identify signs of gliomas, the most common form of brain tumour, with a 90 per cent success rate. Brain tumours often produce ambiguous symptoms, such as headaches, memory or vision problems. A scan is currently the only reliable way to spot them.
