摘 要: | 目的探讨骨肉瘤的X线、CT和MRI诊断价值,提高对原发性骨肉瘤的影像学认识。方法回顾53例经病理证实的原发性骨肉瘤的X线、CT或MRI检查资料。结果53例中经X线检查49例,正确率为89.8%;CT检查10例,正确率为90%;MRI检查32例,正确率为96.9%。骨肉瘤基本影像表现为骨质破坏、骨膜反应、瘤骨和软组织肿块。49例X线表现为成骨型19例,溶骨型13例,混合型17例;X线对骨质破坏、骨膜反应,软组织肿块、瘤骨和Codman三角的检出率分别为61.2%、95.9%、71.4%、73.5%和27.7%;10例CT表现均可见骨质破坏、软组织肿块及瘤骨,CT对骨膜反应、筛孔征和Codrnan三角的检出率为90%、90%和11%:CT对显示细小肿瘤骨和筛孔征最敏感,但对COdman三角的显示不如X线平片;32例MRI表现为骨髓腔内正常的骨髓高信号被肿瘤信号所取代,T1WI呈低~等信号,T2WI呈混杂信号,7例合并出血,24例中央坏死囊变,32例增强扫描均呈不均匀强化及瘤周可见水肿区。结论X线价廉物美,空间分辨力高,是骨肉瘤的首选检查方法,CT、MRI作为X线的补充,可以提供更丰富的诊断信息,对患者治疗方式的决策必须经MRI检查。X线、CT和MRI三者结合,可提高骨肉瘤影像诊断的准确性。

Abstract: | Objective To approach the value of X-Ray, CT and MRI in the diagnosis of osteosarcoma and to improve the understanding level of primary osteosarcoma. Meth-ods Imaging of X-Ray, CT and/or MRI in 53 patients with primary osteosarcoma proved by pathology were reviewed. Results 49 patients were examined by radiography and the exact rate was 89.8%; 10 patients were examined with CT scan and the exact rate was 90%; 32 patients were examined with MRI scan and the exact rate was 96.6% rate. The fundamental imaging ... |
