Abstract
We evaluated the diagnostic ability of low-field-strength (0.2-T) MR imaging by examining 25 meniscal tears which underwent arthroscopy of the knee. Findings from MR imaging and arthroscopy agreed in 24 meniscal tears, and gradient-echo sequence (T1-weighted image) was more useful than spin-echo sequence (proton density-weighted and T2-weighted images). We concluded that low-field-strength (0.2-T) MR imaging may provide useful imformation in the evaluation of meniscal tears of the knee with using proper scan parameters.
