Comparative findings between 111indium-labeled leukocytes and 67gallium scintigraphy for patients with acute and chronic inflammatory diseases.

The sensitivity and specificity for infectious foci for 111In-labeled leukocytes scintigraphy were 60.5%, 78.6%, and those for 67Ga scintigraphy were 94.7% and 47.6%, respectively. The duration of infection and the C-reactive protein levels showed a significant positive correlation with 111In-labeled leukocytes scintigraphy. 67Ga scintigraphy is useful for testing patients with a possible chronic inflammation. Suppurative foci were demonstrated more clearly in ILLS. 111In-labeled-leukocytes were found to be more abundantly present at the center of the lesions. 67Ga scintigraphy showed accumulation in the peripheral area.
