由于低剂量螺旋CT较常规剂量胸片更易于发现肺内结节,故而低剂量CT有可能成为肺癌普查的一种主要方法。全面综述了低剂量螺旋CT实验研究及用于肺癌普查的开展情况和研究成果,并分析了低剂量CT肺癌普查中尚存在的问题。
Because low-dose spiral CT is more likely to detect pulmonary nodules than conventional dose chest X-ray, low-dose CT may be a primary method of lung cancer screening. A comprehensive review of low-dose spiral CT experimental studies and lung cancer screening carried out the status and research results, and analysis of low-dose CT lung cancer screening problems still exist.
