MRI在骨肉瘤诊断中的价值探讨

目的探讨MRI在骨肉瘤诊断中的价值。方法对38例经临床手术病理或活检证实的骨肉瘤MRI影像学资料进行回顾性分析,38例均进行MRI平扫,其中25例平扫后行增强扫描。结果MRI诊断骨肉瘤的准确率达93.9%,肿瘤髓腔内浸润30例,周围软组织侵犯18例,骺板破坏10例,关节软骨受侵4例,尤其是T2加权STIR像和增强扫描在显示上述影像和评价治疗后改变等方面具有较高的敏感性和准确性。结论MRI对骨肉瘤的诊断和临床治疗具有重要意义和价值。

The Evaluation of MRI in Diagnosis of Osteosarcoma

Objective To evaluate the MRI features of osteosarcoma.Methods 38 cases of osteosarcoma proved pathologically were retrospectively analyzed.All of them were examined by plain MRI scan,25 cases were examined by enhanced scan.Results The diagnostic accuracy of osteosarcoma of MRI was 93.9%.There were 30 cases of the extension into the medullary cavity,18 cases of soft tissue mass,10 cases of the destruction in epiphysis and 4 cases of the invasion in articular cartilage,especially T2 weighted STIR image and enhanced MRI scans were advantageous in showing the images mentioned above and in judging of the change after treated.Conclusion MRI is very important in diagnosis and clinical therapy of osteosarcoma.
