Problem

Breast screening required 2 human readers, placing pressure on radiologist capacity.

Approach

The hospital integrated Lunit INSIGHT MMG into routine screening in mid-2023. AI replaced 1 of the 2 human readers. A follow-up analysis compared July 2018–March 2019 with July 2023–March 2024.

Results

over 36%reduction in overall reading time in the historical comparison, per LunitVendor case study[1]
5.5 per 1,000cancers detected after AI adoption, compared with 4.8 before, per LunitVendor case study[1]

Takeaway

The hospital changed the reading workflow rather than adding another review. The comparison used different historical periods and did not isolate AI's causal effect.
