| 摘 要： | 目的探讨影像学表现对长骨骨髓炎和骨肉瘤的鉴别诊断价值。方法回顾性分析59例长骨急、慢性骨髓炎和56例长骨骨肉瘤病人X线、CT和MRI征象。结果骨髓炎组和骨肉瘤组比较,破坏周围松质骨硬化差异无统计学意义(P>0.05),跨过骺板侵犯骨骺、骨皮质改变、骨干髓腔形态改变、MR检查中病变在脂肪抑制T2WI边界清晰、骨膜新生骨类型、死骨形成以及松质骨内脓肿差异有显著性(χ2=9.050~20.647,P<0.01;P=0.001、0.000)。结论病变是否跨越骺板累及骨骺、骨干髓腔形态改变和骨皮质改变对骨髓炎及骨肉瘤鉴别具有一定价值。MR检查中病变在T2WI压脂像中边界清晰和X线检查中CODMAN三角形成是诊断骨肉瘤的可靠征象,髓腔内脓肿和死骨形成是骨髓炎的特异性征象。

| Abstract: | Objective To evaluate the value of imageological manifestations in differential diagnosis of osteomyelitis and osteosarcoma in long bone. Methods The signs on X-ray,CT and MRI in 59 cases with acute or chronic osteomyelitis and 56 with osteosarcoma were analyzed retrospectively. Results Between osteomyelitis and osteosarcoma,the differences of signs were not significant in terms of destruction of spongy bone sclerosis(P>0.05),however,the differences between the two groups were significant in terms of epiphy... |
