| 摘 要： | 目的：探讨NRI在评价骨肉瘤侵袭骨骺中的价值。方法：复习13例骺板未闭骨肉瘤的NRI、X线平片所见，与病理组织学相对比。男3例，女10例；年龄平均11．2(5—15)岁。股骨下端9例，胫骨上端4例。8例化疗结束后再次拍X线平片行NIll检查。结果：所有患者的骺板未闭合，与病理组织学所见对比分析发现X线平片诊断骨肉瘤侵蚀骨骺的准确率为50％，MR的准确率为1000%。8例化疗后已侵蚀骨骺的骨肉瘤并不会完全消失。结论：NRI的检查与病理检查结果相一致。对于指导保留骨骺的保肢术选择具有重要的意义。

| Abstract: | Objective:To study the value of MRI for detecting the epiphyseal extension of osteosarcoma.Methods:Radiography and MRI of 13 patients (3 males,10 females,and with the mean age of 11.2 years) of osteosarcoma with open epiphyseal plates were analyzed.The correlation between transepiphyseal spread of radiological and histopathologic findings was investigated.Results:The epiphyseal plate was affected by osteosarcoma in 38.0% patients with X ray,and in 76.9% with MRI,whereas,histopathologic findings of transepiphyseal extension were correlated with that of MRI.Conclusion:MRI is the most reliable method to determine the epiphyseal involvement. |
