We compared two imaging techniques to assess whether 3D VISTA imaging could replace 2D FSE in diagnosing PCL reconstruction complications.
This retrospective study included 40 patients who underwent surgery of PCL reconstruction and follow-up knee MRI (3D VISTA and 2D FSE) for evaluation of PCL graft integrity. Each image was interpreted independently by two radiologists without knowledge of radiologic reports or clinical history. The diagnostic performance of the 2D FSE PCL view, 3D VISTA PCL view, orthogonal 2D FSE image, and combined sequences were evaluated in terms of sensitivity, specificity, and accuracy for diagnosing complications of PCL graft. The reference diagnoses were made arthroscopically or clinically.
The sensitivities of the 3D VISTA PCL view were similar to those of the 2D PCL view. The sensitivities of the combination of the orthogonal view and the 3D VISTA PCL view were also similar to those of the combination of the orthogonal view and the 2D PCL view. The specificities and accuracies of each image exhibited similar results. There was no statistically significant difference in diagnostic performance between the 3D VISTA PCL view and the 2D PCL view (solitary or combined with the orthogonal view).
The diagnostic performance of the PCL views on 3D VISTA images is comparable to that of 2D FSE images in the diagnosis of PCL graft complications.
我们比较了两种成像技术,以评估 3D VISTA 成像是否可以替代 2D FSE 来诊断 PCL 重建并发症。
这项回顾性研究纳入了 40 例接受 PCL 重建手术并接受膝关节 MRI(3D VISTA 和 2D FSE)随访以评估 PCL 移植物完整性的患者。两名放射科医生独立对每幅图像进行解读,他们不了解放射报告或临床病史。评估了 2D FSE PCL 视图、3D VISTA PCL 视图、正交 2D FSE 图像和组合序列的诊断性能,以评估其诊断 PCL 移植物并发症的敏感性、特异性和准确性。参考诊断是通过关节镜或临床做出的。
3D VISTA PCL 视图的敏感性与 2D PCL 视图相似。正交视图和 3D VISTA PCL 视图组合的敏感性也与正交视图和 2D PCL 视图组合的敏感性相似。每种图像的特异性和准确性均显示出相似的结果。3D VISTA PCL 视图与 2D PCL 视图(单独或与正交视图组合)之间的诊断性能无统计学差异。
在诊断 PCL 移植物并发症方面,3D VISTA 图像上的 PCL 视图的诊断性能可与 2D FSE 图像相媲美。
