Radiology

Introduction:

One must be careful, however, not to develop tunnel vision or search for what one thinks is the most likely diagnosis. The process of lesion detection can be divided into three phases: fixation, recognition, and diagnosis. As the eye scans an image, a vast amount of information is presented to the brain. Fixation occurs when the eye focuses on a portion of the image. Factors that influence how the brain perceives this data include lighting conditions, image sharpness, and image contrast.
