     摘要：[目的]评价计算机X线摄影(CR)、CT、磁共振成像(MRl)在骨肿瘤诊断中的临床价值。[方法]回顾分析55例经病理证实的影像学资料，其中55例均有CR平片，21例CT扫描，20例做了MRI检查。[结果]55例中51例CR片清晰显示骨质改变，40例CR片清晰显示病灶边界，20例CR片清晰显示骨膜反应，19例CR片清晰显示病灶内有大小不一钙化。21例行CT扫描病例均清晰显示骨质改变、病灶边界、病灶内有大小不一钙化，8例清晰显示骨膜反应。20例做了MRI检查病例均清晰显示病灶边界及软组织肿块，8例显示相应骨髓水肿。[结论]CR片仍为骨肿瘤的首选检查方法，CT较好显示了肿瘤的范围及细微结构，MRI对显示肿瘤的范围、软组织肿块及相应骨髓水肿有明显优势。三者相结合有助于骨肿瘤的诊断。
