No difference in sensitivity for occult infection between tropolone- and oxine-labeled indium-111 leukocytes
There is considerable disagreement as to whether oxine or tropolone is the best labeling agent for indium leukocytes. The authors have previously looked at the sensitivity of oxine-labeled /sup 111/In leukocyte scans for occult infections and now present a similar group of patients imaged with tropolone-labeled /sup 111/In leukocytes. Thirty-four patients (38 studies) with possible occult infection were prospectively studied. Patients were imaged 1-4 hr after injection and again at 24 hr postinjection. The differences in sensitivity between oxine and tropolone when imaged early and at 24 hr were not statistically significant. They conclude that there is not significant difference in the ability to detect infection between oxine- and tropolone-labeled leukocytes, both early at 1-4 hr, and on delayed imaging 24 hr after injection.
