[MRI of the ankle joint. Comparison of the 1.0-T and the 0.2-T units].
1999
PURPOSE: Comparison of ankle joint injuries with different MR systems and at different field strengths. METHOD: Ten patients with acute ankle injuries were examined using mid-field (1.0 T) and dedicated low-field (0.2 T) MR units. Findings of ligamentous injury, sinus tarsi involvement, bone injury, and tendon injury were correlated. RESULTS: There was no significant difference between mid- and low-field MR imaging for ligamentous injuries (chi 2 = 0.0395), sinus tarsi changes bone injuries (chi 2 = 0.0507; critical value = 5,991). CONCLUSION: This study showed good agreement in pathological findings in ankle injury on mid-field and low-field MR imaging.
