Prompting in mammography : computer-aided detection or computer-aided diagnosis?
Mark Hartswood, Rob Procter, Linda Jane Williams · 1998
. This paper addresses radiologists' use of Computer-Aided Detection systems in screening mammography. Our focus is on how radiologists interpret prompting information and how this interpretation subsequently effects their decision making. Generally a distinction is made between systems designed to assist radiologists make a more complete examination of a mammogram (detection aids) and those that assist a radiologist to distinguish between benign and malignant lesions (diagnostic aids). We present evidence to show that it is difficult for radiologists to maintain this distinction in practice. We suggest that radiologists are inclined to use prompts as evidence to support diagnostic decisions in cases where they are uncertain about the interpretation of a lesion. It is possible that this mode of use may have a detrimental effect on performance. 1 Introduction The goal of a computer-aided detection system like PROMAM (PROmpting for MAMmography) is to reduce errors by drawing radiologist...
