MRI Diagnostic Value of Meniscal Bucket-handle Tears / 实用放射学杂志

ABSTRACT

Objective To evaluate the diagnostic value of MRI for meniscal bucket-hanle tears. Methods 21patients with bucket-handle tears and 11 patients without bucket-handle tears were put under MRI examinations with the dedicated MRI system(Artoscan 0.2T ESAOTE) and confirmed by arthroscopy.Each was accessed for the presence of (1) the double-anterior sign,(2)the double posterior cruciate ligament sign,(3)the fragment within the intercondylar notch sign and (4)the absent bow tie sign.Results Of 33 cases, the double-anterior sign were seen in 10 cases, the double posterior cruciate ligament sign were seen in 5 cases,the fragment within the intercondylar notch sign were seen in 20 cases and the absent bow tie sign were seen in 25 cases. Conclusion MRI plays an important role in the diagnosis of meniscal bucket-handle tears.The sensitivity and specificity of medial meniscal bucket-handle tears are higher than that of lateral meniscus. The fragment within the intercondylar notch sign is the most valuable sign in diagnosing meniscal bucket-handle tears.
