Summary
This study reviews current radiological techniques for diagnosing spinal osteomyelitis, including plain-films, scintigraphy, ultrasonography, computed tomography, and magnetic resonance imaging. It outlines their diagnostic capabilities and limitations to guide clinical strategy.
Area of Science:
- Radiology
- Medical Imaging
- Orthopedics
Background:
- Spinal osteomyelitis diagnosis relies on various imaging modalities.
- Each technique presents unique strengths and weaknesses.
Purpose of the Study:
- To review current radiological techniques for spinal osteomyelitis.
- To define the semiology, limits, and complementary roles of each method.
- To propose a diagnostic strategy tailored to clinical scenarios.
Main Methods:
- Review of existing radiological techniques: plain-films (and tomography), scintigraphy, ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI).
- Analysis of the semiology (characteristic signs) of each imaging modality.
- Evaluation of the limitations and complementary nature of these techniques.
Main Results:
- Plain-films and tomography offer initial assessment but have limitations in early detection.
- Scintigraphy provides functional information but can lack specificity.
- Ultrasonography is useful for superficial infections and guiding biopsies.
- Computed tomography (CT) excels in demonstrating bony destruction and abscesses.
- Magnetic resonance imaging (MRI) is highly sensitive for early detection, soft tissue assessment, and identifying complications.
Conclusions:
- No single imaging technique is universally superior for diagnosing spinal osteomyelitis.
- A strategic, multi-modal approach combining different radiological methods is essential.
- The choice of imaging should be guided by the clinical presentation and suspected stage of the disease.
