Diagnostic Value of the Direct Low-field MR Arthrography in the Meniscus Degeneration and Tear of Knee / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of the direct MR arthrography in the meniscus degeneration and tear of knee.Methods Thirty subjects undefined by MR imaging having meniscus degeneration and tear of knee underwent MR arthrography.The diagnostic accurate rates in meniscus degeneration and tear by using MR imaging and MR arthrography were evaluated according to the arthroscopy results.Results The diagnostic accurate rates of meniscus degeneration and tear were 80% and 96.7% by conventional MRI scan and MR arthrography respectively.Conclusion The direct low-feild MR arthrography can improve the diagnostic accuracy of meniscus degeneration and tear of knee.
