Magnetic resonance (MR) imaging is highly accurate for diagnosing vertebral osteomyelitis. This study found MR comparable to radionuclide scanning, offering a sensitive and specific method for detecting this bone infection.
Area of Science:
Radiology
Infectious Disease Imaging
Background:
Vertebral osteomyelitis diagnosis can be challenging.
Accurate imaging is crucial for timely treatment.
Purpose of the Study:
To prospectively evaluate magnetic resonance (MR) imaging for diagnosing vertebral osteomyelitis.
To compare the diagnostic performance of MR imaging with radiography and radionuclide studies.
Main Methods:
37 patients with suspected vertebral osteomyelitis were evaluated using MR, radiography, and radionuclide scans.
Imaging findings were correlated with final clinical, microbiologic, or histologic diagnoses.
MR protocols included sagittal and specific echo/repetition time sequences.
Main Results:
MR imaging demonstrated high diagnostic accuracy (94%), sensitivity (96%), and specificity (92%).
Combined bone and gallium scans showed 94% accuracy, 90% sensitivity, and 100% specificity.
Plain radiographs had lower accuracy (73%), sensitivity (82%), and specificity (57%).
Conclusions:
MR imaging is a sensitive and accurate modality for detecting vertebral osteomyelitis.
MR imaging performance is comparable to radionuclide scanning for this condition.
Characteristic MR appearance aids in diagnosing vertebral osteomyelitis.
