为了评估磁共振成像 (MRI) 中软骨厚度测量的准确性，我们将 MRI 软骨厚度测量获得的数据与 14 个人类胫骨近端关节面的相应组织学切片进行了比较。每个近端胫骨关节面被切成五个内侧和外侧切片，每个切片被分为三个扇区，提供 420 个扇区，其中 406 个扇区在我们的研究中进行了评估。总体相关系数(r)为0.96。发现了地形差异。我们的系列中相关系数最低的是内侧胫骨平台的前部（r = 0.88）。 MRI 中的软骨厚度测量在厚度超过 2 毫米的软骨 (r = 0.94) 中比在较薄的软骨层 (r = 0.73) 中更准确。不同级别的骨关节炎的软骨厚度测量结果没有显着差异。然而，在我们的系列中，MRI 和组织学中的软骨厚度之间的平均百分比差异约为 10%。
To assess the accuracy of cartilage thickness measurements in magnetic resonance imaging (MRI), we compared data obtained by cartilage thickness measurements in MRI with corresponding histological sections of 14 human proximal tibial articular surfaces. Each proximal tibial articular surface was cut into five medial and lateral slices and each of these slices was divided into three sectors providing 420 sectors, 406 of which were evaluated in our study. The overall correlation coefficient (r) was 0.96. Topographical differences were found. The lowest correlation coefficient in our series was observed in the anterior part of the medial tibial plateau (r=0.88). Cartilage thickness measurements in MRI were more accurate in cartilage thicker than 2 mm (r = 0.94) than in thinner cartilage layers (r = 0.73). There were no significant differences in cartilage thickness measurements in different grades of osteoarthritis. However, the mean percentage difference between cartilage thickness in MRI and histology was about 10% in our series.
