AI in Clinical Medicine: State of the Field (October 2026)

Where AI for clinical medicine stands in October 2026: validated imaging models, pathology foundation models, large language models tested in real clinics, and AI-discovered drug candidates entering randomized trials. The main takeaway is that retrospective accuracy is common, prospective and real-world evidence is still thin, and benchmark scores need checking against real clinical use.

Sample findings

  • A deep network for chest radiographs was compared retrospectively with practicing radiologists and matched them on some findings but not all.
  • A knee MRI deep learning system was developed and validated retrospectively, with diagnostic variability and interpretation time as the motivating problems.
