AI-supported mammography screening detects more breast cancers than standard double reading by radiologists.
A Swedish randomised trial, a large German implementation study and a separate Swedish prospective study each found more cancers detected when radiologists read with AI support than under standard double reading. Follow-up of the Swedish trial found higher sensitivity with a non-inferior interval-cancer rate. Higher detection is not evidence of lower mortality.

Passage from the sourceAbstract
Artificial intelligence (AI) in mammography screening has shown promise in retrospective evaluations, but few prospective studies exist. PRAIM is an observational, multicenter, real-world, noninferiority, implementation study comparing the performance of AI-supported double reading to standard double reading (without AI) among women (50–69 years old) undergoing organized mammography screening at 12 sites in Germany. Radiologists in this study voluntarily chose whether to use the AI system. From July 2021 to February 2023, a total of 463,094 women were screened (260,739 with AI support) by 119 radiologists. Radiologists in the AI-supported screening group achieved a breast cancer detection rate of 6.7 per 1,000, which was 17.6% (95% confidence interval: +5.7%, +30.8%) higher than and statistically superior to the rate (5.7 per 1,000) achieved in the control group. The recall rate in the AI group was 37.4 per 1,000, which was lower than and noninferior to that (38.3 per 1,000) in the control group (percentage difference: −2.5% (−6.5%, +1.7%)). The positive predictive value (PPV) of recall was 17.9% in the AI group compared to 14.9% in the control group. The PPV of biopsy was 64.5% in the AI group versus 59.2% in the control group. Compared to standard double reading, AI-supported double reading was associated with a higher breast cancer detection rate without negatively affecting the recall rate, strongly indicating that AI can improve mammography screening metrics.
Observational implementation; reader selection and confounding remain possible.
The study claims that AI can perform mammography screening at least as effectively as a second radiologist in detecting breast cancer. This is because one radiologist supported by AI detected 261 cancers compared with 250 detected by two radiologists, producing a 4% higher non-inferior cancer detection rate.[2]
Passage from the sourceFindings
From April 1, 2021, to June 9, 2022, 58 344 women aged 40–74 years underwent regular mammography screening, of whom 55 581 were included in the study. 269 (0·5%) women were diagnosed with screen-detected breast cancer based on an initial positive read: double reading by one radiologist plus AI was non-inferior for cancer detection compared with double reading by two radiologists (261 [0·5%] vs 250 [0·4%] detected cases; relative proportion 1·04 [95% CI 1·00–1·09]). Single reading by AI (246 [0·4%] vs 250 [0·4%] detected cases; relative proportion 0·98 [0·93–1·04]) and triple reading by two radiologists plus AI (269 [0·5%] vs 250 [0·4%] detected cases; relative proportion 1·08 [1·04–1·11]) were also non-inferior to double reading by two radiologists.

Written by AI from the published cases and the sources they cite. It describes what each side argues and what the readable sources show, and is not a ruling from Koinovera. The generation date does not guarantee that the claim wording or sources are unchanged. It only changes when someone asks for an update.

Every argument made about this claim, each with its own reasoning and sources.
Strongest orders cases by how readers have rated their reasoning, weighted by the standing of those readers and lowered when a case rests on poorly rated sources. Cases nobody has rated sit in the middle, newest first. It never counts how many cases or sources there are.
