目的:探讨并比较用MRI检查与用CT检查诊断脊柱转移瘤的临床价值,以提高我院对脊柱转移瘤的检出率。方法:对我院2009年3月～2012年4月收治的34例脊柱转移瘤患者的CT及MRI影像学资料进行回顾性分析,并在分析过程中比较用CT检查和用MRI检查诊断脊柱转移瘤的敏感性。结果:①在此34例患者中,经CT检查确诊患有脊柱转移瘤的患者有18例,其诊断敏感率为52.9%;经MRI检查确诊患有脊柱转移瘤的患者有32例,其诊断敏感率为94.1%。用MRI检查诊断脊柱转移瘤的敏感率高于用CT检查诊断脊柱转移瘤的敏感率,且两者间的差异具有显著性(p<0.05)。②经CT检查,此34例患者的病变例数、受累椎骨节数、压缩骨折节数、椎管及椎旁软组织肿块数分别为82例、74个、29个和6个;经MRI检查,此34例患者的病变例数、受累椎骨节数、压缩骨折节数、椎管及椎旁软组织肿块数分别为167例、133个、30个和14个。MRI检查在确诊病变例数、受累椎骨节数、椎管及椎旁软组织肿块数方面优于CT检查,且两者间的差异具有显著性(p<0.05);MRI检查在确诊压缩骨折节数方面与CT检查无显著性差异(p>0.05)。结论:与用CT检查相比,用MRI检查诊断脊柱转移瘤的敏感性更高,检出病变例数、受累椎骨节数、压缩骨折节数、椎管及椎旁软组织肿块数的几率更大。
Objective: To explore and compare the clinical value of MRI and CT in the diagnosis of spinal metastases, in order to improve the detection rate of spinal metastases in our hospital. Methods: The CT and MRI imaging data of 34 patients with spinal metastases who were treated in our hospital from March 2009 to April 2012 were analyzed retrospectively. CT and MRI were used in the analysis to diagnose spinal metastasis Tumor sensitivity. RESULTS: Among the 34 patients, 18 cases were diagnosed as having spinal metastases by CT, and the diagnostic sensitivity was 52.9%. 32 cases diagnosed as having spinal metastases by MRI were diagnosed Sensitivity was 94.1%. The sensitivity of MRI in the diagnosis of spinal metastases was higher than that of CT in the diagnosis of spinal metastases, and the difference was significant (p <0.05). ②The number of lesions, the number of involved vertebrae, the number of compression fractures, the number of spinal canal and paravertebral soft tissue mass in the 34 patients were 82, 74, 29 and 6 respectively after CT examination. After MRI examination, The number of lesions, the number of vertebrae involved, the number of compression fractures, the number of spinal canal and paravertebral soft tissue mass in the 34 patients were 167, 133, 30 and 14, respectively. MRI examination was superior to CT examination in diagnosing the number of lesions, the number of involved vertebrae, the number of spinal canal and paravertebral soft tissue mass, and there was significant difference between the two (p <0.05) There was no significant difference between CT and CT (p> 0.05). CONCLUSIONS: MRI is more sensitive to diagnose spinal metastases compared with CT, and the number of lesions detected, the number of vertebrae involved, the number of fractures, the number of spinal and paraspinal soft tissue lesions are more likely to be detected .
