摘要 目的探讨三维双回波稳态序列在腕关节三角纤维软骨复合体损伤的临床应用价值。方法对41例有尺侧腕部疼痛,临床怀疑为腕关节TFCC损伤的患者行磁共振扫描,包括脂肪抑制质子密度加权像序列(PDWI-TSE-FS)、脂肪抑制快速自旋回波T2加权像序列(T2WI-TSE-FS)和三维双回波稳态成像序列(3D-DESS)。通过对不同序列上TFCC的MRI信号改变程度,对比分析3D-DESS序列与SE常规序列上显示损伤的检出率差异。结果 3D-DESS序列和T2WI-TSE-FS序列、PDWITSE-FS序列对TFCC损伤检出率分别为78%(32/41)和68%(28/41)、63.4%(26/41)。3D-DESS序列与常规序列相比较有差异学统计意义(P<0.05)。另外3D-DESS序列中21例表现为全层软骨损伤,11例表现为部分软骨损伤,T2WI-TSE-FS序列分别为22例和6例;PDWI-TSE-FS序列为21例和5例。结论 3D-DESS序列能发现早期的部分软骨损伤,对TFCC的细微病损有较明显的诊断价值。
