目的 肺部疾病种类繁多,肺部肿块样病变是影像诊断的重点和难点.肺部最常见的肿块病变主要有肺癌、炎性团块、肺结核,因此对以上三种病变的准确定性有重要的临床意义.不仅可以指导临床制定正确的诊疗手段,也可以避免错误治疗及过度治疗给患者带来不必要的损伤,同时可以减少医疗资源浪费.宝石能谱CT特有的成像方式及强大的图像后处理技术可以对肺部肿块做出更为全面准确的诊断.“,”There are a wide variety of lung diseases. Lung tumor-like lesions are the emphasis and difficulty in imaging diagnose. The most common types of lung tumor-like lesions mainly have lung cancer, inflammatory mass and tuberculosis. Therefore, an accurate qualitative of these three diseases has important clinical significance. Not only can guide clinical diagnosis and treatment, but also avoid the unnecessary injury to the patients caused by wrong treatment and over-treatment. Meanwhile, it can reduce the waste of medical resources. Precious spectral CT characteristic imaging methods and powerful image post-processing techniques can make more full and accurate diagnosis of lung mass.
