螺旋CT增强扫描对孤立性肺结节的诊断意义

目的探讨螺旋CT增强扫描诊断孤立性肺结节的价值。方法回顾性分析手术病理证实的肺癌25例、肺炎结节13例、结核瘤6例的螺旋CT增强扫描的表现。结果肺癌和肺炎结节增强扫描的强化程度明显高于结核瘤(P<0.01)。肺炎结节强化峰值的时间较肺癌结节延迟。肺癌结节增强扫描出现点、条状强化征像。结论螺旋CT增强扫描对孤立性肺结节的诊断具有重要意义。

Objective To investigate diagnosis value of enhanced helical CT scan on solitary pulmonary nodules. Methods The enhanced helical CT finding of pulmonary carcinomas 25 cases and inflammation nodules 13 cases and tuberculoma 6 cases by proved operation or pathological were studied retrospectively. Results The pulmonary carcinomas and inflammation nodules showed a significance higher degree of delayed enhancement than tuberculoma. The inflammation nodules showed higher degree of enhanced than pulmonary carcinomas on the enhanced helical CT imags. The pulmonary carcinomas have dot and stripe sign on the enhanced helical CT imags. Conclusion The enhanced helical CT scans are importance in the diagnosis of Solitary Pulmonary Nodules.
