[Abstract] Objective: To quantitatively analyze brucellar spondylitis (BS) by applying dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI), and to evaluate the value of quantitative DCE-MRI in the stating of BS.Materials and methods: Analyzed 28 BS patients with complete biochemical detection or operation data (17 males and 11 females; mean age 52 years old). All patients received routine MRI and DCE-MRI examinations. Volume transfer constant (Ktrans), rate constant (Kep), extravascular extracellular volume fraction (Ve) and plasma volume fraction (Vp) of diseased vertebral bodies of the patients were measured in perfusion parameter maps. The four parameters were compared among the diseased vertebres and the non-diseased vertebres, Ktrans, Kep were compared the acute group and the non-acute group by t-test.Results: Ktrans, Kep, Ve and Vp showed statistically significant differences (P<0.05) between the diseased vertebrae and the non-diseased vertebrae. Ktrans was 1.723±0.266, Kep was 2.177±0.690 in the acute group, Ktrans was 2.177±0.690, Kep was 1.508±0.877 in the non-acute group, it showed statistically significant differences (P<0.05).Conclusions: DCE-MRI quantitative analysis has great value in the diagnosis and staging of BS.
