动态增强CT扫描对20例肺内硬化性血管瘤的影像学诊断

Diagnosis of pulmonary sclerosing hemangioma with incremental dynamic CT:analysis of 20 cases

目的 探讨动态增强CT扫描对肺内硬化性血管瘤影像诊断的价值。方法 对 2 0例肺内硬化性血管瘤进行研究 ,增强前后均对病变局部薄层扫描 ,层厚及间隔均为 2 0mm。结果 肺内硬化性血管瘤呈圆形或类圆形 ,边缘光整 ,实质密度均匀 ,少数病灶可有钙化。动态增强扫描病灶明显均匀强化 ,CT值最大可达 90～ 110HU。

Objective To evaluate the value of incremental dynamic CT in the diagnosis of pulmonary sclerosing hemangioma (sclerotic hemangioma) Methods Thin section CT at 2 0 mm thickness and 2 0 mm interval was performed before and after administration of contrast material in 20 cases of pulmonary sclerosing hemangioma Results Pulmonary sclerosing hemangiomas were shown to be round or oval masses, with smooth margins, homogenous parenchymal density, and occasional calcification Homogenous enhancement was evident in all cases, with maximum CT values ranging from 90 to 110 HU Conclusion Spiral dynamic CT is useful in the diagnosing of sclerosing hemangioma in the lungs
