Perception and Cognition in Medical Imaging

  • Haris Chrysikopoulos


Visual assessment proceeds simultaneously at two levels: a rapid overview of the entire image as a unit, and a slow deliberate scrutiny of selected parts of the image. Our visual behavior is intertwined with our cognitive labor of data analysis and data synthesis, and is supported by our experience and fund of knowledge. Our attention is easily drawn to any obvious patterns and any obvious isolated findings. At the same time we can direct our gaze and attention to specific parts of the image, at will, depending on the clinical question, the patient’s history, and any obvious imaging findings. Biases and errors, such as inattentional blindness, hinder our ability to evaluate the image objectively and thus we may not “pick up” a crucial or a pertinent finding.
