title: A comparison of four standard scintigraphic TV displays: concise communication.
abstract: Four displays (pseudocolor mappings) available on a standard color TV are compared using two series of images (100 normal brains and 100 normal livers) with 50 computer-simulated lesions superimposed on each set. Four observers viewed the sets of images in such a way that the order of the display methods for both organs formed two orthogonal Latin squares. The observers were asked to locate and rate, on a standard scale, the most apparent area in each image, and ROC analysis was applied to the results. The "heated-object spectrum" was shown to be a useful display for brain images. It was also shown that the choice of display depends on the organ to be imaged.
