A test bank of verified chest radiographs was compiled for visual search experiments to investigate radiology performance in the detection of early lung cancer. A measure of the physical characteristics of the lesions was derived to determine the conspicuity (x) of the nodules and to investigate possible causes of failed detection. Observer performance was measured by alternate free response operating characteristic (AFROC) methodology and was supplemented with visual search recording. Correlation of AFROC scores and the x values was poor but inspection of the visual search recordings showed that most nodules were fixated. Fixations on missed lesions produced average dwell times greater than three times the minimum duration thought to be associated with detection. We conclude that the majority of errors were failures of decision rather than detection and comment on the implications of this for strategies to improve diagnostic effectiveness.

Does Expectation of Abnormality Affect the Search Pattern of Radiologists When Looking for Pulmonary Nodules?

“…An analysis on the dwell time of TPs vs FNs (Table 8) indicated a significantly longer dwell time on lesions with a true positive decision regardless of the clinical information provided. This finding supports the findings of Manning et al [24] and Nodine et al [32]. It suggests that this is an indication of more extensive information processing.…”

Viewing another person's eye movements improves identification of pulmonary nodules in chest x-ray inspection.

“…This interpretation is consistent with previous studies showing that extended viewing of x-rays often leads to an increase in the number of false positives (Christensen et al, 1981;Edwards, Ricketts, Dubbins, Roobottom, & Wells, 2003;Manning et al, 2004), whereas faster decision times are typically an indicator of expertise (Nodine et al, 2002).…”

Worth a quick look? Initial scene previews can guide eye movements as a function of domain-specific expertise but can also have unforeseen costs.

“…The ability to exploit the initial glimpse of the scene is at the core of the holistic model (Kundel et al, 2007) but is also a key component of scene perception research (Castelhano & Henderson, 2007;Torralba et al, 2006;Wolfe et al, 2011). By using the FPMW paradigm to control the contribution of the initial glimpse on subsequent search as a function of expertise, the present study extends previous eye-tracking research that has until now only been able to indirectly investigate these issues, either via tachistoscopic studies (Carmody et al, 1981;Kundel et al, 1975;Evans et al, 2013) or free viewing studies (Donovan & Litchfield, 2013;Kundel et al, 1978;Kundel et al, 2008;Manning et al, 2004).…”
