目的探讨肺腺癌成骨型脊柱转移瘤的CT与MR表现及其对应关系。方法回顾性分析经临床病理证实的76例肺腺癌成骨型脊柱转移瘤患者的完整的CT与MR资料,对病灶的形态、密度、病灶边缘骨质改变、信号强度,信号均匀性等指标进行分析。结果 76例肺腺癌脊柱成骨型转移瘤患者共扫描脊椎640个,180个脊椎受累,发现成骨型转移病灶220个。CT表现为椎体内的单发或多发结节状、环状或不规则形高密度影,无正常骨小梁结构。MR病灶T1WI及T2WI均呈不同程度低信号。结论肺腺癌成骨型脊柱转移瘤病灶CT与MR表现具有一定特征,成骨型脊柱转移瘤CT平扫密度与MR T2WI信号强度有相关性。
Objective To investigate the CT and MR findings of osteogenic spine metastases of lung adenocarcinoma and their corresponding relationship. Methods The complete CT and MR data of 76 patients with sporadic bone metastases of lung adenocarcinoma confirmed by clinicopathologic analysis were retrospectively analyzed. The morphological features, density, borderline bone changes, signal intensity, signal uniformity and other indexes Analyze. Results Sixty-six patients with sporadic osteosarcoma metastatic lung adenocarcinoma were scanned with 640 vertebrae and 180 vertebrae, and 220 osteogenic metastatic lesions were found. CT showed single or multiple vertebral nodular, ring or irregular high-density shadow, no normal trabecular structure. MR lesions T1WI and T2WI showed varying degrees of low signal. Conclusion The CT and MR findings of osteogenic spine metastases of lung adenocarcinoma have some characteristics. The CT scan density of osteogenic spondylosis is correlated with the signal intensity of MR T2WI.
