Searching for bone fractures: a comparison with pulmonary nodule search

C H Hu et al. Acad Radiol. 1994 Sep.

Abstract

Rationale and objectives: We aimed to determine if the characteristics and principles of visual search described for the detection of pulmonary nodules apply to extremity fractures.

Methods: The eye positions of staff orthopedic radiologists, radiology residents, and medical students were monitored as they searched hand and wrist X-ray images for fractures and a chest image for nodules.

Results: More systematic scanning patterns were observed for experienced observers than inexperienced observers. Positive decisions for bone images were associated with prolonged gaze durations; prolonged gaze durations were significantly longer for false-negative versus true-negative decisions. Intercluster jump distances were found to be greater for chest images than bone images.

Conclusions: A search for bone fractures can be qualitatively characterized by classifying observer scan paths, dwell times, and jump distances. Gaze duration can be a useful predictor of bone image locations containing potential missed fractures. Perceptual feedback could aid observers in the detection of inconspicuous fractures.
