摘　　要：目的 探讨恶性骨肿瘤的磁共振征象特点。方法 选取我院2013年5月~2014年7月经术后病理证实为恶性骨肿瘤患者25例和良性骨肿瘤患者20例作为研究对象,对其术前MRI征象和病理学征象进行回顾性分析,比较异常征象在良、恶性骨肿瘤患者中的发生率。结果 骨内异常信号合并实性软组织肿块、放射状骨膜反应与骨膜三角、肿瘤周围水肿3种异常征象多集中表现于恶性组患者中,与良性组患者比较差异有统计学意义（P〈0.05或P〈0.01）。而3种异常征象在各类型恶性骨肿瘤疾病中均未表现出明显区别,差异无统计学意义（P〉0.05）。结论 骨内异常信号合并实性软组织肿块、放射状骨膜反应与骨膜三角、肿瘤周围水肿3种异常征象较多发生于恶性骨肿瘤患者中,其中骨内异常信号合并实性软组织肿块可作为MRI检测鉴别诊断良、恶性骨肿瘤的依据。Objective To study the characteristic of MRI of bone tumors. Methods From May 2013 to July 2014,25 patients examined by postoperative pathology with malignant bone tumors and 20 patients examined by postoperative pathology with benign bone tumors were selected.The preoperative MRI signals and pathological manifestations were analyzed retrospectively,and the incidence of abnormal signals in benign and malignant bone tumor patients were compared. Results Abnormal signals together with solid soft tissue mass,radical periosteal reaction and codman triangle,edema around the tumor were more found in malignant bone tumors,compared with the benign bone tumors,the difference was statistically significant（P〈0.05 or P〈0.01）.While the three abnormal signals had no significant difference among different types malignant bone tumors（P〉0.05）. Conclusion Abnormal signals together with solid soft tissue mass,radical periosteal reaction, codman triangle and edema around the tumor are more found in malignant bone tumors,and abnormal signals together with solid soft tissue mass can be used as a basis for MRI detection diagnose of the benign or malignant bone tumors.
