Computer-aided detection
Older imaging software that marks areas of interest for a clinician to confirm. Branded CAD in the 2000s partly to avoid the word AI after earlier hype. Same basic idea as today's detection-assist tools.
A breast screening service still runs an older CAD system that places marks on most exams, nearly all on normal tissue or benign calcifications. At two marks per exam and 80 exams a session, a reader clears about 160 marks and learns to dismiss each one in a second, which is the habit that lets a rare true mark slip past. When evaluating a newer detection tool, measure its marks per normal exam on a sample of your own screening cases, and multiply by a session's volume before weighing its sensitivity figure.
