OBJECTIVE: The objective of our study was to better define the T1-weighted MRI characteristics of surgically proven pedal osteomyelitis. CONCLUSION: Decreased T1 marrow signal in a geographic medullary distribution with a confluent pattern and concordance with fat-suppressed T2- and T1-weighted postcontrast signal abnormality was present in 100% of the surgically proven cases of pedal osteomyelitis. None of the patients with decreased T1 marrow signal in a subcortical distribution or in a hazy, reticulated pattern had surgically proven osteomyelitis regardless of the fat-suppressed T2-weighted or postcontrast T1-weighted findings.
