AI summary: Harvard Medical School researchers have developed an artificial intelligence (AI) tool that could improve the treatment of brain tumors. The machine learning technology can analyze gliomas, the most common brain tumor, faster and more accurately than traditional methods, reducing operating time and potentially improving treatment outcomes. The AI tool, which is still several years away from clinical use, could also help determine the invasiveness of a tumor, aiding decisions on treatment methods. The research follows similar efforts in the UK to use AI in cancer detection and treatment.
