CADe devices identify and mark candidate findings. The clinician decides whether each mark represents something real and what it means. Mammography CAD is the longest-established example, and real-time polyp detection during colonoscopy is the newest.

Where This Gets Misread

CADe has a long and cautionary history. Early mammography CAD was widely deployed and later large studies found no improvement in outcomes and increased recall rates. The lesson was that marking findings changes reader behavior in ways that do not automatically help, which is exactly the concern with current concurrent-read AI.
