FIGURE 5. Typical set of true-positive PEM-I images, with upper row showing 7 emission images from breast with suggestive findings and lower row showing images from contralateral breast. Each image frame represents 1 slice through breast, with upper edge of frame corresponding to region of breast closest to chest wall and leftmost frame corresponding to image plane closest to upper detector. Localized region of preferential FDG uptake is visible in upper set of images. Pathologic evaluation of excised mass revealed infiltrating and intraductal carcinoma (2.5 x 2.2 x 2.2 cm, histologic grade 3 [Bloom Richardson], nuclear grade III).
