摘要
目的 :以关节镜为标准 ,确定 3D -Volume -FFE -T1WI对髌股关节软骨退变的诊断价值。方法 :48个人膝关节行关节镜检查及 3D -Vloume -FFE -T1WI矢状位扫描。矢状位图像行多平面重建 (MPR)处理。MR图像每个髌股关节分内、外侧髌骨面、股骨滑车面与关节镜图像逐一对照分析。结果 :关节镜下发现 10 2个病变软骨面 ,3D -Volume -FFE -T1WI对软骨病变的分级和关节镜分级间有显著正相关性 (P <0 .0 1)。结论 :3D -Volume -FFE -T1WI结合MPR评价髌股关节软骨退变和关节镜评价关节软骨有很好的相关性。
Objective: The value of 3D-Volume-FFE-T1 WI MRI sequence imaging was determined for detecting patellofemoral articular cartilage degeneration using arthroscopy as the standard of reference. Methods: Forty-eight knee joints underwent subsequent arthroscopy were imaged with three-dimensional sagittal FFE-T1 WI. Sagittal images were administrated with multiple-planar reconstrution (MPR) techniques. Each patellofemoral articular surface was divided into media and lateral patellar facets, trochlear facets compared with arthroscopy face to face. Results: Arthroscopy showed 102 cartilage defects. Good correlation existed between MR gradation of 3D-Volume-FFE-T1WI and arthroscopy gradation in assessment of cartilage abnormalities ( P <0.01). Conclusions: Good correlation and mutual aid existed between arthroscopy and 3D-Volme-FFE-T1WI combined with MPR techniques in assessment of articular cartilage.
