对 16 个软骨样基质病变的磁共振 (MR) 图像和组织学研究进行了回顾，以确定是否可以辨别任何独特的形态或信号特征。对十个经活检证实的非软骨样骨病变的形态和信号特征进行了比较。在通过长重复时间和长回波时间获得的所有透明软骨病变的图像上，肿瘤基质在定义的小叶结构中具有均匀高信号强度的独特外观。相对于肌肉的高信号区域对应于透明软骨基质的区域，其成分均匀、细胞结构低、含水量高；小叶形态特征具有相同的组织学相关性。软骨母细胞瘤、透明细胞软骨肉瘤和滑膜软骨瘤病显示出更多的细胞间质，仅具有分散的软骨样基质岛，并且与所有 MR 序列上的肌肉相比，呈等信号或低信号。在十个非软骨样骨病变中没有看到独特的小叶状、高强度 MR 表现。
Magnetic resonance (MR) images and histologic studies of 16 chondroid-matrix lesions were reviewed to determine if any distinctive morphologic or signal features might be discerned. Ten biopsy-proved non-chondroid bone lesions were compared in terms of configuration and signal characteristics. The tumor matrix had a distinctive appearance of homogeneous high signal intensity in a defined lobular configuration on images of all hyaline cartilage lesions obtained with a long repetition time and a long echo time. The areas of hyperintensity relative to muscle corresponded to areas of hyaline cartilage matrix with its uniform composition, low cellularity, and high water content; the lobular morphologic characteristic had an identical histologic correlate. The chondroblastomas, clear-cell chondrosarcoma, and synovial chondromatosis demonstrated a much more cellular stroma, with only scattered islands of chondroid matrix, and were isointense or hypointense compared with muscle on all MR sequences. The distinctive lobular, high-intensity MR appearance was not seen in the ten non-chondroid bone lesions.
