OBJECTIVE: To examine the interobserver reliability of magnetic resonance imaging
(MRI) signs of osteomyelitis in complex chronic pressure ulcers in patients with
spinal cord injury (SCI). DESIGN: Retrospective review study. SETTING: Specialist
SCI rehabilitation center. PARTICIPANTS: Adult patients with SCI and pressure
ulceration investigated with MRI. INTERVENTIONS: Analysis of MRI examinations and
clinical records collected over a 4-year period. Images were independently
assessed by 2 experienced radiologists for osteomyelitis based on assigned
predictive indicators including cortical bone erosion, soft tissue edema, deep
collections, heterotopic new bone, hip effusion, and abnormal signal change of
the marrow. MAIN OUTCOME MEASURES: Interobserver agreement for indicative MRI
signs of osteomyelitis in complex pressure ulcers. RESULTS: Thirty-seven patients
underwent 41 MRI scans. Concordance for marrow edema was 71% on both short tau
inversion recovery and T1-weighted sequences, and for cortical erosion was 85%.
CONCLUSIONS: For the assessment of pelvic osteomyelitis related to pressure
ulcers, the T1-weighted MRI signal for marrow edema and cortical erosion has
strong interobserver agreement.
