摘要
目的
2
对比分析1.5T常规MRI和放射状MRI在髋关节盂唇撕裂中的诊断价值。
方法
2
回顾性分析2018年4-11月在本院行关节镜手术证实为髋臼唇撕裂，且术前行1.5T髋关节常规MRI和髋臼放射状MRI扫描的患者22例临床资料。两位高年资骨关节影像医师分别评估常规MRI和放射状MRI图像，观察是否存在髋臼唇撕裂及撕裂部位，并与关节镜结果进行比较分析，评估1.5T常规MRI和放射状MRI在髋关节盂唇撕裂中的诊断价值。
结果
2
以关节镜评估结果为金标准，常规MRI诊断盂唇撕裂的敏感性、特异性、准确性分别为37.2%、86.9%、54.5%、阳性预测值84.2%、阴性预测值42.5%；放射状MRI扫描技术诊断盂唇撕裂的敏感性、特异性、准确性分别为93.0%、87.0%、90.9%、阳性预测值93.0%、阴性预测值86.9%。
结论
2
1.5T盂唇放射状MRI扫描对髋关节盂唇撕裂较常规MRI具有更高的诊断价值，能够对盂唇撕裂情况进行更加全面准确的评估。
Abstract
Objective
2
To compare the diagnostic performance of 1.5T radial magnetic resonance imaging (MRI) and conventional MRI for acetabular labrum tear.
Methods
2
We retrospectively analyzed the clinical data of 22 patients with acetabular labrum tear confirmed by hip arthroscopy
who underwent surgeries in our hospital between April and November
2018. All the patients underwent examinations with both conventional MRI and radial MRI of the hips before the operations
and the imaging data were read by two senior radiologists independently. The MR findings were compared with the findings by hip arthroscopy to assess the performance of 1.5T radial MRI and conventional MRI for the diagnosis of acetabular labrum tear.
Results
2
The diagnostic sensitivity
specificity
accuracy
positive predictive value (PPV) and negative predictive value (NPV) of conventional MRI for acetabular labral tear were 37.2%
86.9%
54.5%
84.2% and 42.5%
and those of radial MRI were 93.0%
87.0%
90.9%
93.0%
and 86.9%
respectively.
Conclusion
2
1.5T radial MRI of the hip is superior to conventional MRI for diagnosing acetabular labral tear and allows more accurate and comprehensive assessment of the condition.
