CAD becomes a spell-check for small polyps
By Frances Rylands-Monk
Computer-aided detection (CAD) can only enhance performance if used correctly, and it does not reduce the need for training, according to a presentation on Friday at ECR 2015 in Vienna. CAD for colonography has shown promise, but radiologists need to understand sensitivity and specificity issues, as well as when CAD should be deployed.
