目的：评价三维（3D）快速自旋回波（FSE）与可变翻转角（“CUBE”）磁共振成像（MRI）在膝关节成像中的疗效和效率，并与常规MRI进行比较。材料和方法：2011年1月至2011年12月期间，29例（单膝）不同程度关节损伤患者入选本研究。所有患者均接受常规MRI和脂肪抑制CUBE MRI序列。所有患者随后在MRI检查后2周内由经验丰富的骨科医生进行膝关节镜手术。根据关节镜检查结果提供的标准参考，分别计算CUBE和常规MRI技术检测软骨病变、半月板撕裂和前交叉韧带损伤的敏感性、特异性和准确性。统计学处理采用卡方检验，P <0.05。结果：对于关节软骨病变的评价，CUBE序列具有更高的敏感性（70.9%对50.6%，p < 0.01），更高的特异性（72.6%对58.9%，p < 0.05）和更高的准确性（71.8%对55.2%，p = 0.001）。对于半月板撕裂的评价，CUBE和常规MRI具有相似的灵敏度、特异性和准确性（p = 0.20-0.55）。同样，在前交叉韧带损伤的检测中，CUBE成像和常规成像之间的敏感性、特异性或准确性无显著差异（p = 0.13-0.65）。结论：CUBE MRI在膝关节损伤的综合评价中具有与常规成像方案相似或上级的敏感性、特异性和准确性。(C)2012年皇家放射科医师学院。由爱思唯尔有限公司出版。保留所有权利。
AIM: To evaluate the efficacy and efficiency of three-dimensional (3D) fast spin-echo (FSE) with variable flip angle ("CUBE") magnetic resonance imaging (MRI) in knee imaging as compared with conventional MRI.MATERIALS AND METHODS: Twenty-nine patients (single knee) with joint injuries of varying degrees were enrolled in this study between January, 2011 and December, 2011. All patients underwent conventional MRI and a fat-suppressed CUBE MRI sequence. All patients subsequently underwent knee arthroscopic surgery performed by an experienced orthopaedic surgeon within 2 weeks after the MRI examinations. With standard reference provided by arthroscopic results, the sensitivity, specificity, and accuracy of both the CUBE and conventional MRI techniques were calculated for detecting cartilage lesions, meniscus tears, and anterior cruciate ligament injuries, respectively. A chi-square test was used for statistical analysis with a level of significance of p < 0.05.RESULTS: For the evaluation of articular cartilage lesions, the CUBE sequence had higher sensitivity (70.9% versus 50.6%, p < 0.01), higher specificity (72.6% versus 58.9%, p < 0.05), and higher accuracy (71.8% versus 55.2%, p = 0.001) than conventional MRI. For the evaluation of meniscus tears, CUBE and conventional MRI had similar sensitivity, specificity, and accuracy (p = 0.20-0.55). Similarly, there was no significant difference in sensitivity, specificity, or accuracy between CUBE imaging and conventional imaging in the detection of anterior cruciate ligament injuries (p = 0.13-0.65).CONCLUSION: CUBE MRI has similar or superior sensitivity, specificity, and accuracy to a conventional imaging protocol in the comprehensive evaluation of knee joint injuries.
