To review concepts of perception and cognition as they relate to chest radiology. To present a summary of established research on detection and characterization of pathology in chest radiology. Examine the interplay of exam characteristics and observer perception/cognition in missed cases.

Basic model of detection in radiology  Visual search patterns  Feature detection  Interpretation   Anatomy of the eye and detection of detail   Influence of display characteristics on perception Resolution, contrast, luminescence, and other factors Ergonomic factors   Research on search patterns in chest radiology Pattern of search in beginners and experts Search time and efficiency   Research on pulmonary nodule detection Search and satisfaction of search Detection errors Interpretation errors Use of computer aided detection Examples of characteristic types of misses on chest CT

Awareness of the processes of perception/detection and of characteristic types of radiologic misses is an important part of improving quality of diagnosis in chest radiology. An understanding of basic perceptual and cognitive factors related to chest CT diagnosis is important to avoid these common pitfalls.
