0 5 10 15 20 25 30 Abscess/blood ratios

Figure 9. Abscess/blood ratios for several inflammation radiopharmaceuticals. Leukocytes lead to much higher accumulation ratios than passive diffusion agents. (Adapted from data in McAfee J et al, J Nucl Med 1991; 32:2126-2131.)

Figure 10. 111in-ieukocyte scan with transient nonspecific lung accumulation in a patient suffering from "sepsis syndrome". (A) Diffuse lung accumulation (arrow) is seen 4 hours post-injection (left) that clears by 24 hours (right). (B) The source was subsequently localized to a liver abscess (diagonal arrows) localized by dual isotope 99mTc-sulfur colloid liver (left) and 111In-leukocyte imaging (lower right). images in the upper half of the panel are anterior views of the liver and in the lower half right lateral views.
