Abstract

PURPOSE

To evaluate the diagnostic performance of three-dimensional fast spin-echo (3D FSE-Cube) without fat suppression (NFS) for detecting knee lesions, using comparison to 3D FSE-Cube with fat suppression (FS).

MATERIALS AND METHODS

One hundred twenty-four patients who underwent 1.5T knee magnetic resonance imaging (MRI) scans and 25 subsequent arthroscopic surgeries were retrospectively reviewed. Using arthroscopic results and two-dimensional images as reference standards, diagnostic performances of 3D FSE-Cube-NFS and FS imaging about lesions of ligament, meniscus, subchondral bone marrow edema (BME), and cartilage were compared. Scan parameters of 3D FSE-Cube imaging were previously optimized by a porcine knee phantom.

RESULTS

No significant differences were observed between detection rates of NFS and FS imaging for detecting lesions of meniscus and cartilage (p>0.05). However, NFS imaging had lower sensitivity for detection of medial collateral ligament (MCL) tears, and lower sensitivity and specificity for detection of BME lesions, compared to FS imaging (p<0.05).

CONCLUSION

3D FSE-Cube-NFS imaging showed similar diagnostic performance for detecting lesions of meniscus or cartilage compared to FS imaging, unlike MCL or BME lesions.

摘要

目的

通过与三维快速自旋回波脂肪抑制序列(3D FSE-Cube-FS)对比,评估三维快速自旋回波序列(3D FSE-Cube)非脂肪抑制(NFS)技术检测膝关节病变的诊断效能。

材料与方法

回顾性分析124例行1.5T膝关节磁共振成像(MRI)检查并随后接受25例关节镜手术患者的资料。以关节镜检查结果及二维图像作为参考标准,比较3D FSE-Cube-NFS和FS成像对韧带、半月板、软骨下骨髓水肿(BME)及软骨病变的诊断效能。3D FSE-Cube成像扫描参数先前已通过猪膝关节模型进行优化。

结果

NFS和FS成像对半月板及软骨病变的检出率差异无统计学意义(p>0.05)。然而,与FS成像相比,NFS成像对内侧副韧带(MCL)撕裂的检出敏感性较低,对BME病变的检出敏感性和特异性均较低(p<0.05)。

结论

与FS成像相比,3D FSE-Cube-NFS成像对半月板或软骨病变的诊断效能相似,但对MCL或BME病变的诊断效能不同。
