摘要

方法对 50 名踝关节损伤患者进行 DECT 和 MRI 扫描。对关节表面进行分析。CT 和 MRI 图像由两名诊断医生独立评估。以 MRl 为参考标准，比较了能谱 CT 和 MRI 的诊断能力。评估了 MR 和 CT 结论的一致性。能谱 CT 采用虚拟脱钙技术。结果距骨韧带撕裂前 EDCT 的 80keVCT 值、混合 keV 值和 Rho 值均明显低于完整韧带。最佳临界值为 80keV，CT 值为 65HU。混合 KeV 值为 64.5。结论DECT对距骨胫骨前韧带撕裂的诊断准确可靠。

Findings of energy spectrum CT in anterior talofibular ligament injury of ankle joint

Objective

To evaluate the diagnostic value of energy spectrum CT in structural injury of anterior talofibular ligament using MRI as reference standard.

Methods

50 patients with ankle injury were scanned by DECT and MRI. The articular surface was analyzed. CT and MRI images were independently evaluated by two diagnostic physicians. Using MRl as the reference standard, the diagnostic ability of energy spectrum CT and MRI was compared. The consistency of MR And CT conclusions was evaluated. Energy spectrum CT adopts virtual decalcification technology. 80keVCT value and mixed keV value were used in MRI.

Results

The 80keVCT value, mixed keV value and Rho value of EDCT before the tear of talofibular ligament were significantly lower than that of intact ligament. The optimal critical value was 80keV and CT value was 65HU. The mixed keV value was 64.5. There was no difference in diagnosis between MRI and DECT.

Conclusion

DECT is accurate and reliable in the diagnosis of anterior talofibular ligament tear.
