CR、CT、MRI在骨肿瘤诊断中的临床价值

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。

Clinical value of CR, CT and MRI in bone tumor

Objective]To investigate the clinical value of computed radiography(CR),computed tomography(CT)and magnetic resonance imaging(MRI)in bone tumor.Method]Fifty-five patients with histologically confirmed bone tumor underwent imaging examinations.55 patients were performed CR,21 CT and 20 MRI.Result]CR of 51 patients clearly revealed bone changes.CR of 40 patients well showed marginal of tumor.20 tumors appeared periosteal reaction onCR and 19 calcification on CR.CT scan of 21 patients clearly depictedbone changes,marginal and calcification and CT scan of 8 revealed periosteal reaction.MRI scan of 20 patients showed margin of tumor and soft-tissue mass and bone marrow edema was prominent in 8 patients.Conclusion]CR is the first choice of imaging approach for born tumor.CT well reveal the extent and minute structure of the bone tumor.The extent,soft-tissue mass and bone marrow edema are more dramatically demonstrated on MRI imaging.CR,in addition to CT and MRI,is helpful in diagnosis of bone tumor.
