description | PURPOSE: To assess the role of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusionweighted imaging (DWI) in diagnosing diabetic foot osteomyelitis (DFO). MATERIAL AND METHODS: Twenty-five participants with suspected osteomyelitis were included, who underwent MRI including DCE-MRI and DWI sequences. It was subsequently followed by bone biopsy and microbiological analysis (gold standard). The participants were divided into 2 groups based on biopsy results: DFO-positive or DFO-negative. The semi-quantitative DCE-MRI parameters (SI(0), SI(max), SI(rel), wash-in rate [WIR], and type of curve) and apparent diffusion coefficient (ADC) values were subsequently compared between the 2 groups. RESULTS: Out of the 25 cases, 19 were DFO-positive and 6 were DFO-negative on bone biopsy. The SI(0), SI(max), and WIR were significantly higher in DFO-positive cases (p-value 0.050, 0.023, and 0.004, respectively). No difference was seen in SI(rel). 100% negative cases revealed type-I curve, and 94% of positive cases showed type-II curve. SI(0) > 143.4 revealed a sensitivity of 94.7% and specificity of 83.3%. SI(max) had a sensitivity of 89.5% but lower specificity of 67.7% at a cut-off value of 408.35. The most significant difference was seen with WIR; p-value ~0.004. At the cut-off value of > 1.280, it had a specificity and sensitivity of 100% and 76%, respectively. Also, ADC values below 1.57 × 10(-3) had a sensitivity of 88.2% and specificity of 80% for diagnosing DFO. CONCLUSIONS: DWI and DCE-MRI provide non-invasive sequences, which can help to increase the overall specificity and sensitivity of conventional MRI for the diagnosis of osteomyelitis, differentiating it from acute Charcot’s arthropathy. |
