Abstract

RATIONALE AND OBJECTIVES

To analyze the diagnostic performance of MDA-MPR with CT for evaluating ACL structural continuity.

METHODS

A total of 145 patients with highly suspected ACL injury admitted to our hospital between January 2016 and May 2021 were retrospectively enrolled. All patients had undergone examination with MRI, CT, and arthroscopy. Taking arthroscopy results as the gold standard, the diagnostic accuracy for identifying ACL rupture by MRI and MDA-MPR with CT were compared.

RESULTS

The receiver operator characteristic curves demonstrated that both MRI and MDA-MPR with CT performed well in the diagnosis of ACL tears. The sensitivities of MRI and MDA-MPR with CT for diagnosing complete ACL tears were 95.16% (59/62) and 90.32% (56/62), respectively. Their specificities in this regard were 77.11% (64/83) and 84.34% (70/83), respectively. MRI had a higher sensitivity but MDA-MPR with CT had a higher specificity for detecting complete ACL tears, and the differences were statistically significant (p <.05). The sensitivities of diagnosing partial ACL tears using MRI and MDA-MPR with CT were 78.79% (26/33) and 75.76% (25/33), respectively, while the specificities were 86.61% (97/112) and 90.18% (101/112), respectively. These differences were non-significant (p >.05).

CONCLUSION

MDA-MPR with CT has high diagnostic efficiency for ACL injuries, especially in the diagnosis of complete ACL tears.

摘要

背景与目的

分析多平面重建（MPR）结合 CT 多期动态增强扫描（MDA-MPR）对前交叉韧带（ACL）结构连续性的诊断效能。

方法

回顾性分析 2016 年 1 月至 2021 年 5 月间我院收治的 145 例高度怀疑 ACL 损伤患者的临床资料。所有患者均行 MRI、CT 和关节镜检查。以关节镜检查结果为金标准，比较 MRI 和 MDA-MPR 对 ACL 撕裂的诊断准确性。

结果

受试者工作特征曲线分析结果显示，MRI 和 MDA-MPR 对 ACL 撕裂的诊断效能均较高。MRI 和 MDA-MPR 对完全性 ACL 撕裂的诊断敏感度分别为 95.16%（59/62）和 90.32%（56/62），特异度分别为 77.11%（64/83）和 84.34%（70/83）。MRI 对完全性 ACL 撕裂的诊断敏感度较高，但 MDA-MPR 对完全性 ACL 撕裂的诊断特异度较高，差异均有统计学意义（p<0.05）。MRI 和 MDA-MPR 对部分性 ACL 撕裂的诊断敏感度分别为 78.79%（26/33）和 75.76%（25/33），特异度分别为 86.61%（97/112）和 90.18%（101/112）。两种方法的诊断敏感度和特异度差异均无统计学意义（p>0.05）。
