Radiology

The useful meeting, unfortunately, exists Meetings are usually where productivity goes to file a complaint. But there is one kind of meeting that high-stakes work still needs: the review session where a first draft is challenged, evidence is checked, and a senior decision-maker signs off. Radiology has long understood this. A resident may draft the report. A fellow may question the interpretation. An attending radiologist resolves the remaining uncertainty. The point is not ceremony. The point is controlled disagreement. ...

Scan You Believe It? Why RadAgent Makes Medical AI Show Its Work Hospitals do not merely need an AI that can write a radiology report. They need an AI whose work can be checked before the report becomes somebody else’s problem. That sounds obvious, which is exactly why it is often ignored. A chest CT is a dense three-dimensional diagnostic object. A radiologist does not just glance at it, produce prose, and walk away. They inspect anatomy, compare regions, test impressions, look for omissions, and decide whether a finding is actually supported by the scan. Many vision-language models, by contrast, still behave like a polished black box: scan in, report out, confidence implied by typography. ...

Translation is one of those AI use cases that sounds almost too reasonable to argue with. English medical data exist in large quantities. Many healthcare systems, researchers, and educators need non-English clinical text. Large language models are fluent, cheap, and obedient enough to produce thousands of translated reports before lunch. The spreadsheet smiles. The budget owner relaxes. The governance team is told that quality will be checked by another LLM. ...

CT scans are not photographs. This is a small fact with expensive consequences. A normal image model can pretend that visual understanding is mostly a matter of looking at a flat picture. A CT volume does not offer that courtesy. It is dense, three-dimensional, and full of clinically relevant details that may occupy only a small part of the scan. Feed the whole thing into a multimodal large language model, and the model faces a choice: compress the volume aggressively, sample a few slices, or ask the GPU to become a radiologist with a power bill. ...

Chest X-rays are not mysterious objects. They are images that radiologists interrogate through a disciplined sequence: find the anatomy, measure what matters, compare against criteria, and then make a diagnostic judgment. The modern vision-language model often skips the middle of that sequence. It looks at the image, produces a polished explanation, and hopes the reader will not ask too aggressively where the evidence came from. This is how medical AI becomes impressive in a demo and uncomfortable in a clinic. Fluency is cheap. Verifiability is expensive. ...
