目的比较CT与MRI对脊柱转移瘤的诊断价值。方法选择2010年1月至2015年6月符合诊断标准的脊柱转移瘤患者40例,均行CT及MRI检查,比较其对脊柱转移瘤诊断符合率及受累病灶符合率。结果 MRI诊断脊柱转移瘤符合率(92.50%)高于CT符合率(72.50%),差异有统计学意义(P<0.05)。MRI椎骨受累检出率(89.66%)、椎管受累检出率(94.26%)及椎旁软组织肿块检出率(96.87%)均高于CT,差异有统计学意义(P<0.05)。结论脊柱转移瘤MRI诊断准确率高于CT,对转移瘤类型的判断及对各种微小病变的检出率较高,可作为脊柱转移瘤诊断的首选方法。
Objective To compare the diagnostic value of CT and MRI in spinal metastases. Methods Forty patients with spinal metastases who met the diagnostic criteria from January 2010 to June 2015 were examined by CT and MRI. The diagnostic accuracy rate and the coincidence rate of affected lesions were compared. Results The coincidence rate of MRI diagnosis of spinal metastasis (92.50%) was higher than that of CT (72.50%), the difference was statistically significant (P <0.05). The detection rate of vertebral involvement (89.66%), detection of spinal canal involvement (94.26%) and paravertebral soft tissue mass (96.87%) were significantly higher than those of CT (P <0.05). Conclusions The accuracy of MRI diagnosis of spinal metastases is higher than that of CT. The diagnosis of spinal metastases is the first choice for the diagnosis of metastatic tumors and the detection rate of various small lesions.
