I Used Claude Code to Get a Second Opinion on My MRI

What happened

Developer Antoine Posepny published a blog post about using Claude Code with Opus 4.8 as a second opinion when reading his MRI scan. The post reached the front page of Hacker News with 307 points.

Context and impact

Claude Code was given the full DICOM export, autonomously searched for and installed Python libraries (pydicom, numpy, matplotlib), wrote an analysis pipeline, and produced a secondary interpretation. The author emphasizes this doesn't replace a radiologist, but shows how agentic coding tools indirectly open up 'quasi-medical' applications for non-experts. HN discussion centered on hallucination risks for health data.
