(99m)Tc-interleukin-8 for imaging acute osteomyelitis.

Abstract

In this rabbit model of osteomyelitis, (99m)Tc-IL-8 clearly revealed the osteomyelitic lesion. Although the absolute uptake in the osteomyelitic area was significantly lower than that obtained with (99m)Tc-MDP and (67)Ga-citrate, the T/Bs were significantly higher for (99m)Tc-IL-8 because of fast background clearance. The ease of preparation, good image quality, and lower radiation burden suggest that (99m)Tc-IL-8 may be a suitable imaging agent for the scintigraphic evaluation of acute osteomyelitis.
