Please always present the confusion matrix. One number is (almost) useless. I can detect 100% by def detect(x): Return True

This fails actually (assuming it's Python), "return" needs smaller case "r". But you could rewrite it in Haskell or Rust for safety.

The original study: https://link.springer.com/article/10.1007/s11547-025-02161-1

It was retrospective-only, i.e. a case series on women who were known to have breast cancer, so there were zero false negatives and zero true negatives, because all patients in the study truly had cancer.

The AI system used was a ConvNet used commercially circa 2021, which is when the data for this case series were collected.

Does this mean that newer AI systems would perform significantly differently?

In the human follow-up, there was an improvement but there was still a gap:

> Their findings offered reassurance: DWI alone identified the majority of cancers the AI had overlooked, detecting 83.5% of missed lesions for one radiologist and 79.5% for the other.

The combination of AI and this DWI methodology seems to identify most of the cancer, but there’s still about 20% of 1/3 that gets missed. I assume that as these were confirmed diagnoses, they were caught with another method beyond DWI.

Shouldn't A.I. not be used in a way that it only tries to assist? E.g. a doctor takes a look first and if (s)he can't find anything then A.I. is checking as well (or in parallel).

My personal opinion: AI should be still kept out of anything mission critical, in all stages, except for evaluation.

There is other comment very correctly noting that this result is on 100% positive input. Same AI in “real life” would score probably much better eventually. But as you point out, if used as a confirmation tool, is definitely bad.
