Neonatal osteomyelitis examined by bone scintigraphy

Area of Science:

• Pediatric Imaging
• Nuclear Medicine
• Skeletal Infections

Background:

• Osteomyelitis is a serious bone infection in infants.
• Early diagnosis is crucial for effective treatment and preventing complications.
• Radiographs are often the initial imaging modality but can be insensitive in neonates.

Purpose of the Study:

• To evaluate the utility of bone scintigraphy in diagnosing osteomyelitis in neonates.
• To compare scintigraphic findings with radiographic and clinical data.
• To establish optimal imaging protocols for suspected neonatal osteomyelitis.

Main Methods:

• Bone scintigraphy was performed on 33 infants under six weeks of age with suspected osteomyelitis.
• Scintigraphic results were correlated with radiographic findings and microbiological/clinical data.
• Image quality and diagnostic accuracy were assessed.

Main Results:

• Twenty-five of 25 confirmed osteomyelitis sites showed abnormal radionuclide uptake.
• Ten additional sites with abnormal uptake were detected, which were radiographically normal.
• Scintigrams of neonates were comparable in quality and diagnostic information to those of older children.

Conclusions:

• Bone scintigraphy is a highly sensitive and specific tool for diagnosing osteomyelitis in neonates.
• It can detect infection earlier than radiographs, especially in the growth plate complex.
• Bone scintigraphy should be considered in all neonates with suspected osteomyelitis after initial radiographs.
