Overview
Three phasic radionuclide imaging with 99m Tc is a modality for early diagnosis of acute osteomyelitis.
Bone Scan
- Radionuclide imaging can be valuable in suspected bone infection, especially early in the course of infection and if multiple foci are suspected or an unusual site is suspected, as in the pelvis.
- Technetium-99 methylene diphosphonate (TC 99m), accumulates in areas of increased bone turnover and is the preferred agent for radionuclide bone imaging (3 phase scan).
- Inflammation and increased vascularity in osteomyelitis result in increased concentration on 99m Tc especially on the 3rd phase (4-6hr later).[1]
The following video and images show bone scans of patients with osteomyelitis.
