目的:探讨滑膜骨软骨瘤病的DR诊断价值。方法:收集32例,均摄相应关节正侧位片,部分行CT检查,其中男性20例,女性12例,最小年龄19岁,最大年龄66岁,平均年龄42岁。结果:29例患者具有典型X线表现,2例在传统X线检查中未发现软骨体钙化影,在DR片中发现浅淡不明显的钙化影,经手术证实为软骨体钙化,1例DR显示正常,CT值测量显示不明显软骨体钙化。结论:DR较传统X线检查率有所增高,但是受软骨体钙化、骨化的程度影响,在早期诊断仍有其局限性。 Objective: To investigate the diagnostic value of DR in synovial osteochondromatosis. Methods: Thirty-two cases were collected. All the patients underwent lateral CT scan. There were 20 males and 12 females. The minimum age was 19 years old and the maximum age was 66 years. The average age was 42 years old. RESULTS: Twenty-nine patients had typical X-ray findings. Two patients did not find calcification of cartilage in traditional X-ray examination. In patients with DR, no obvious calcification was found. Calcification of cartilage was confirmed by surgery. One patient had DR Show normal, CT value measurement showed no obvious cartilage calcification. Conclusion: Compared with the traditional X-ray examination, the DR rate is increased. However, due to the degree of cartilage calcification and ossification, there are still some limitations in the early diagnosis.
