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.
