目的：评价跟腓骨韧带（CFL）斜冠状位MRI对CFL损伤的诊断价值及诊断准确性。材料和方法：本回顾性研究包括91例疑似CFL损伤并行CFL显像的患者。通过MRI正交序列和CFL影像对CFL进行解剖鉴定。两名放射科医生根据整个长度视图、整个宽度视图和使用四分制的边缘清晰度来评估CFL。通过计算敏感性、特异性和准确性来评估使用正交和CFL视图的诊断准确性。关节镜或临床表现作为参考标准。结果：两位读者都发现，使用CFL视图图像的整个长度、整个宽度和锐边缘来识别病变优于基于正交图像的识别。CFL影像诊断CFL损伤的敏感性和准确性均显著高于正交影像，但特异性与正交影像无显著差异。结论：CFL显像能更好地进行解剖评价，提高诊断CFL损伤的敏感性和准确性。因此，CFL视图图像应用于评估潜在的CFL损伤。(C) 2014年英国皇家放射学院。Elsevier Ltd.出版。版权所有。
AIM: To evaluate the usefulness and diagnostic accuracy of oblique coronal MRI of the calcaneofibular ligament (CFL) view for diagnosis of CFL injury.MATERIAL AND METHODS: This retrospective study included 91 patients who were suspected to have CFL injury who underwent CFL view imaging. Anatomical identification of the CFL on orthogonal MRI sequences and CFL views was evaluated. Two radiologists evaluated the CFL based on an entire length view, an entire width view, and margin sharpness using a four-point scale. Diagnostic accuracy using orthogonal and CFL views was evaluated by calculating sensitivity, specificity, and accuracy. Arthroscopic or clinical findings were used as the reference standard.RESULTS: Both readers found identification of lesions using the entire length, entire width, and sharp margin from CFL view images to be superior to that based on orthogonal images. The sensitivity and accuracy of diagnosing CFL injury were significantly higher when using the CFL view compared to the orthogonal view, although specificity was not significantly different between the CFL view and orthogonal view images.CONCLUSIONS: CFL view imaging enables better anatomical evaluation and improved sensitivity and accuracy of diagnosis of CFL injury. CFL view images should therefore be used to evaluate potential CFL injuries. (C) 2014 The Royal College of Radiologists. Published by Elsevier Ltd. All rights reserved.
