Visual nudge improves accuracy of mammogram readings

False negatives and positives plague the reading of mammograms, limiting their usefulness. Cindy Grimm, a computer scientist at Washington University in St. Louis, and colleagues have shown the accuracy of novice readers can be improved by nudging them visually to follow the scanpath of an expert radiologist. The “nudge” is a brief change in the brightness or warmth in the image in the peripheral field of view.
