| 目的 对比MRI标准冠状位与多平面重建（MPR）图像评估前外侧韧带（ALL）的价值。方法 纳入130例接受膝关节MR检查患者，分别针对标准冠状位MRI及MPR图识别ALL，并将ALL分为完全可见、部分可见及不可见；比较双侧ALL在2种图像中的可见性，并以Kappa检验进行一致性分析。结果 130例中，标准冠状位MRI及MPR图中，左侧ALL分别有93例及83例完全可见、21例及12例部分可见、26例及25例不可见，右侧ALL分别有66例及80例完全可见、29例及15例部分可见、各有35例不可见。双侧ALL在标准冠状位MRI和MPR图中的可见性差异均有统计学意义（P均<0.05）而一致性均极好（Kappa均>0.80）。结论 MPR显示ALL效果较标准冠状位MRI更佳，但在无法满足其扫描条件时，利用标准冠状位MRI也可较准确地评估ALL。 |

| Objective To compare the value of standard coronal MRI and multi-planar reconstruction (MPR) images for evaluation of anterolateral ligament (ALL). Methods Data of 130 patients who underwent knee joint MR examination were retrospectively analyzed, including standard coronal MRI and MPR images. ALL were identified on standard coronal MRI and MPR images and classified as fully visible, partially visible or invisible. The visibility of bilateral ALL on both standard coronal MRI and MPR images were compared, while Kappa test was used to evaluate the consistency on both kinds of images. Results Among 130 cases, on standard coronal MRI and MPR images, the left ALL was fully visible in 83 and 93 cases, partially visible in 21 and 12 cases but invisible cases in 26 and 25 cases, respectively, while the right side ALL was fully visible in 66 and 80 cases, partially visible cases in 29 and 15 cases but invisible cases each in 35 cases, respectively. Significant difference of visibility of bilateral ALL were found between standard coronal MRI and MPR images (both P<0.05), both with excellent consistency (both Kappa>0.80). Conclusion MPR could display bilateral ALL better than standard coronal MRI. If the scanning conditions for MPR could not be met, standard coronal MRI might be used to evaluate ALL rather accurately. |
