The way that diagnostic images are read can have a substantive effect on the accuracy of clinical decisions. This session focuses on sequential reading effects in the context of medical imaging with screening mammography serving as an example application. Considerable effort from the breast imaging community has been devoted to optimizing the technology used to acquire and process the image data. Far less is known about the mechanisms by which characteristics of the image readers impact diagnostic accuracy, even though the large variability or reader performance is well established. In this session, three speakers approach this topic with perspectives ranging from neuroscience and vision, to large scale screening program assessment. The presentations will describe various mechanisms that produce sequential effects in the context of reading medical images, give examples of measurements demonstrating sequential effects in clinical data, and explore visual adaptation in more depth as a potential mechanism.

Learning Objectives:
1. Understanding sequential effects
2. Examples of clinical studies that motivate investigation of sequential effects
3. Understanding visual adaptation as a perceptual mechanism
