To compare image quality between three-dimensional volume isotropic turbo spin echo acquisition (3D VISTA) with the posterior cruciate ligament (PCL) view and two-dimensional (2D) fast spin echo (FSE) for evaluation of PCL injury.
This retrospective study included 60 patients with clinical suspicion of PCL injury who underwent both 2D FSE and 3D VISTA of the knee between January 2015 and December 2015. The diagnostic performance of each oblique coronal view and the combined images was evaluated for sensitivity, specificity and accuracy for diagnosing a PCL tear. The arthroscopically confirmed diagnoses were used as the reference standard. Data were analyzed using the McNemar test.
The mean contrast-to-noise ratio was significantly higher for 3D VISTA than for 2D FSE. The two imaging modalities did not differ significantly in anatomical identification ability, with the exception of margin sharpness, which was inferior for 3D VISTA with Reader 2 (p = 0.038). When we classified the diagnoses of PCL injury as normal or abnormal, there were no significant differences in sensitivity, specificity or accuracy between the PCL view of 3D VISTA and 2D FSE images (p > 0.05).
3D VISTA had a superior contrast-to-noise ratio than 2D FSE and similar image quality in the evaluation of the PCL. The PCL view of 3D VISTA has the same diagnostic ability as 2D FSE in the diagnosis of PCL injury and can thus replace 2D FSE. Advances in knowledge: The oblique coronal view 3D VISTA MRI has similar diagnostic ability to 2D FSE in the diagnosis of PCL injury, and therefore 3D VISTA image can replace 2D FSE.
比较三维容积各向同性涡轮自旋回波采集（3D VISTA）后交叉韧带（PCL）视图与二维（2D）快速自旋回波（FSE）在评估PCL损伤时的图像质量。
这项回顾性研究纳入了60例临床怀疑PCL损伤的患者，这些患者在2015年1月至2015年12月期间接受了膝关节的2D FSE和3D VISTA检查。评估每个斜冠状面视图和联合图像在诊断PCL撕裂时的敏感性、特异性和准确性。关节镜确诊的诊断结果用作参考标准。数据采用McNemar检验进行分析。
3D VISTA的平均对比噪声比显著高于2D FSE。除边缘清晰度外，两种成像方式在解剖识别能力上无显著差异，对于读者2而言，3D VISTA的边缘清晰度较差（p = 0.038）。当将PCL损伤的诊断分为正常或异常时，3D VISTA的PCL视图与2D FSE图像在敏感性、特异性或准确性方面无显著差异（p>0.05）。
在评估PCL时，3D VISTA的对比噪声比优于2D FSE，且图像质量相似。3D VISTA的PCL视图在诊断PCL损伤方面与2D FSE具有相同的诊断能力，因此可以替代2D FSE。知识进展：斜冠状面3D VISTA MRI在诊断PCL损伤方面与2D FSE具有相似的诊断能力，因此3D VISTA图像可以替代2D FSE。
