摘　　要：目的评价直接法低场MRI膝关节造影对半月板退变与损伤的诊断价值。方法对30例MRI平扫不能明确诊断半月板退变与损伤的病人,进行膝关节直接法造影,以膝关节镜检查为诊断金标准,对比分析常规MRI和直接法MRI膝关节造影对半月板退变与损伤的诊断准确率。结果常规MRI平扫对半月板退变与损伤的诊断准确率为80%,直接法关节腔造影的诊断准确率为96.7%,效果显著。结论直接法MRI膝关节造影能够提高半月板退变与损伤的诊断。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.
