目的对比分析X线平片、CT及MRI在脊椎转移瘤中的诊断价值,探讨其临床适用性。方法选择2010年6月-2012年6月我院98例脊椎转移瘤患者,分别采用X线、CT和MRI进行检查和诊断,观察三种方法的影像学表现和检出情况。结果 MRI的病变椎体检出率96.11%,明显高于X线的52.22%和CT的75.00%,差异有统计学意义(P<0.05)。结论常规的X线平片可以发现大部分脊椎转移瘤,CT可以显示普通X线平片不容易发现的早期少量骨质破坏,而MRI与常规X平片、CT比较,更加具有敏感性和特异性,可以更早地发现和诊断脊椎转移瘤。
Objective To compare and analyze the diagnostic value of X-ray, CT and MRI in spinal metastases and to explore its clinical applicability. Methods From June 2010 to June 2012, 98 patients with spinal metastases in our hospital were examined and diagnosed by X-ray, CT and MRI respectively. The imaging findings and detection of the three methods were observed. Results The detection rate of vertebral body in MRI was 96.11%, which was significantly higher than that of X - ray 52.22% and CT 75.00%, the difference was statistically significant (P <0.05). Conclusion Conventional X-ray can detect most of the metastatic tumors of the spine. CT can show early small amount of bone destruction that is not easily detected in plain radiographs. MRI is more sensitive and specific than conventional X-ray and CT Sex, can be found earlier and diagnosis of spinal metastases.
