X线平片与CT诊断脊椎转移瘤的临床对比研究

X-ray and CT Diagnosis of Spinal Metastatic Tumor Clinical Comparative Study

目的探讨X线平片与CT诊断脊椎转移瘤的临床价值,以期为临床诊断提供良好的依据。方法回顾性分析2010年12月至2012年12月在陕西省宝鸡市中心医院进行影像学检查的35例脊椎转移瘤患者的临床资料,分别运用X线平片、CT检查,比较两者在诊断上的差异。结果 X线平片和CT在椎管受累、软组织肿胀、病理性骨折、骨质破坏或缺损、椎体形态改变上比较差异有统计学意义(P<0.05),且两者在细微的病变中也有明显的差异,CT可发现X线平片无法显示的病变情况。结论优质的X平片能显示出脊椎转移瘤,而CT则对于发现早期的脊椎转移瘤以及细微的病变情况上有明显优势。

Objective To study the clinical value of X-ray and CT diagnosis for spinal metastatic tumor,in order to provide a good basis for clinical diagnosis.Methods Retrospective analysis on clinical data of 35 cases of spinal metastatic tumor for imaging inspection in Central Hospital of Baoji randomly selected from December 2010 to December 2012 was done,difference in diagnosis of X-ray and CT examination was compared.Results X-ray and CT had statistically significant difference（P 0.05） in the spinal canal involvement,soft tissue swelling,pathological fracture,bone destruction or defect,and vertebral body shape change,and obvious differences were observed in small lesions that CT could display lesions which couldn＇t be found on X-ray plain film.Conclusion The high quality X-ray can show spinal metastatic tumor,and CT has obvious advantages in finding the early spinal metastatic tumor and subtle lesions situation.
