| Popis: | Two diabetic patients with cellulitis and surgically proven gangrene of the toes were evaluated with combined Tc-99m MDP bone scans and In-111 WBC scans. The bone scans showed unusual cold areas in the area of the gangrene. The WBC scans were positive in both cases. In each case, the imaging technique was to label the patients WBCs with 500 μCi of In-111. The next day, a three-phase bone scan was performed using a medium-energy collimator and dual-isotope imaging. This procedure allows precise overlapping of the Tc-99m MDP bone and In-111 WBC images. In each of these cases, the bone tracer was unable to localize in the gangrenous area because of the impairment to blood flow. The WBCs, which had the advantages of a) 24 hours to localize, and b) the fact that WBCs can move outside of vascular channels, were able to identify the infection. |
