Summary
Magnetic resonance (MR) imaging effectively identified the extent and location of chronic osteomyelitis infections in eight patients. MR showed excellent correlation with surgical findings, highlighting infected areas and related complications.
Area of Science:
- Medical imaging
- Orthopedics
- Radiology
Background:
- Chronic osteomyelitis presents diagnostic challenges.
- Accurate assessment of infection extent is crucial for effective treatment.
- Conventional imaging modalities may have limitations in visualizing all aspects of osteomyelitis.
Purpose of the Study:
- To evaluate the utility of 1.5 T Magnetic Resonance (MR) imaging in preoperative assessment of chronic osteomyelitis.
- To determine the correlation between MR findings and surgical outcomes.
- To compare the advantages of MR imaging over CT and scintigraphy for osteomyelitis evaluation.
Main Methods:
- Magnetic resonance (MR) imaging at 1.5 Tesla was performed.
- Imaging was conducted preoperatively and prior to aspiration in eight patients.
- T2-weighted images were utilized to identify infected areas.
Main Results:
- Excellent correlation was observed between MR findings and surgical findings in all eight patients.
- Infected intraosseous and extraosseous areas showed increased signal intensity on T2-weighted images.
- MR imaging successfully visualized sequestra, sinus tracts, and soft tissue abscesses.
Conclusions:
- Magnetic resonance (MR) imaging is a valuable tool for determining the extent and location of chronic osteomyelitis.
- MR imaging offers direct visualization of infection foci, potentially surpassing CT and scintigraphy.
- Preoperative MR imaging aids in surgical planning and improves outcomes for chronic osteomyelitis patients.
