Acute hematogenous osteomyelitis: has the bone scan betrayed us?

Area of Science:

• Nuclear medicine
• Radiology
• Infectious disease imaging

Background:

• Acute hematogenous osteomyelitis is a serious bone infection.
• Accurate diagnosis is crucial for effective treatment.
• Radiological imaging plays a key role in diagnosis.

Purpose of the Study:

• To describe the diagnostic findings of Technetium-99m bone scanning in acute hematogenous osteomyelitis.
• To evaluate the utility of Gallium-67 citrate imaging in challenging cases.

Main Methods:

• Review of Technetium-99m phosphate bone scan findings.
• Correlation with clinical and microbiological data.
• Consideration of Gallium-67 citrate imaging when indicated.

Main Results:

• Technetium-99m bone scans demonstrate a range of abnormalities, both "hot" (increased uptake) and "cold" (decreased uptake).
• These findings can be variable and sometimes inconclusive.
• Gallium-67 citrate imaging provides complementary information in specific situations.

Conclusions:

• Technetium-99m bone scanning is a valuable tool for diagnosing acute osteomyelitis but can yield varied results.
• Gallium-67 citrate imaging serves as a useful adjunct when Technetium-99m scans are equivocal.
• Integrated imaging approaches improve diagnostic accuracy for osteomyelitis.
