The clinical value of two-dimensional ultrasound in examining the menisci of the knee compared to other methods is controversial. We studied the utility diagnosed by three-dimensional sonography in evaluating meniscal tears.
96 menisci with standardised artificial lesions were examined in a bath of Ringer solution. Two-dimensional ultrasound was compared to three-dimensional ultrasound, which creates three-dimensional reconstruction of sequential ultrasonographic images.
The three-dimensional ultrasound had a higher sensitivity of 88% vs 69% with a specificity of 83% vs 94% for the diagnosis of meniscal tears compared with the two-dimensional method. The sensitivity in imaging was 54% in each case for longitudinal tears, 63% vs 96% for horizontal tears, 67% vs 37% for oblique tears and 54% vs 0% for radial tears. The difference of these results, however, was not statistically significant. Radial tears were more frequently diagnosed by three-dimensional sonography.
In our model, sonographic diagnosis of meniscal tears was improved only partially by using three-dimensional ultrasound. Whether in vivo other factors alter the minimal differences between the two techniques is the subject of ongoing investigation.
与其他方法相比，二维超声检查膝关节半月板的临床价值存在争议。我们研究了三维超声在诊断半月板撕裂中的效用。
在林格氏溶液浴中对96个具有标准化人工损伤的半月板进行检查。将二维超声与三维超声进行比较，三维超声可对连续超声图像进行三维重建。
与二维方法相比，三维超声诊断半月板撕裂的敏感性更高，分别为88%和69%，特异性分别为83%和94%。纵向撕裂的成像敏感性在每种情况下均为54%，水平撕裂为63%对96%，斜向撕裂为67%对37%，放射状撕裂为54%对0%。然而，这些结果的差异无统计学意义。放射状撕裂通过三维超声检查更常被诊断出来。
在我们的模型中，使用三维超声仅部分改善了半月板撕裂的超声诊断。体内其他因素是否会改变这两种技术之间的微小差异是正在进行研究的课题。
