BACKGROUND
This study aimed to assess a novel ultrasound (US) scanning approach in evaluating knee femoral cartilaginous defects, compared with magnetic resonance imaging (MRI, commonly used for knee imaging) and arthroscopy (gold standard).
METHODS
Sixty-four consecutive patients (65 knees) were prospectively evaluated between April 2010 and July 2011.
RESULTS
The overall sensitivity (62.2 and 69.4%), specificity (92.9 and 90.5%), accuracy (75.4 and 78.5%), and adjusted positive (88.7 and 90.4%) and negative predictive (69.5 and 73.3%) were similar for both radiologists (weighted κ = 0.76). Furthermore, agreement between grading by US and MRI was substantial (weighted κ = 0.61).
CONCLUSIONS
In conclusion, the novel US scanning approach allows similar diagnostic performance compared to routine MRI for knee cartilage defects. US is more accessible, easier to perform, and less expensive than MRI, with potential advantages of easier initial screening and assessment of cartilage defects.
背景
本研究旨在评估一种新型超声（US）扫描方法在评估膝关节股骨软骨缺损方面的效果，并与磁共振成像（MRI，常用于膝关节成像）和关节镜检查（金标准）进行比较。
方法
在2010年4月至2011年7月期间，对64例连续患者（65个膝关节）进行了前瞻性评估。
结果
两位放射科医生的总体敏感性（分别为62.2%和69.4%）、特异性（分别为92.9%和90.5%）、准确性（分别为75.4%和78.5%）以及调整后的阳性预测值（分别为88.7%和90.4%）和阴性预测值（分别为69.5%和73.3%）相似（加权κ = 0.76）。此外，超声和MRI分级之间的一致性较高（加权κ = 0.61）。
结论
总之，对于膝关节软骨缺损，新型超声扫描方法与常规MRI具有相似的诊断性能。超声比MRI更容易获得、操作更简便且成本更低，在软骨缺损的初步筛查和评估方面具有潜在优势。
