摘要
目的：探讨多层螺旋CT（MSCT）扫描在肺磨玻璃结节（GGN）检查中的应用价值。材料与方法：对50例GGN病例进行肺部常规剂量和低剂量MSCT扫描,观察GGN的形态、大小、密度、内部特点和结节边缘等情况。结果：常规剂量MSCT扫描发现45个GGN,低剂量MSCT扫描发现40个GGN,GGN直径为5-20 mm,其中26例GGN患者诊断为原发性肺腺癌。结论：MSCT低剂量扫描对于GGN有较高的检出率,可应用于早期肺癌的筛查。
Purpose： To explore the application value of multi-slice spiral CT（ MSCT） scan in detecting pulmonary ground-glass nodules（ GGN）. Materials and Methods： Conventional dose MSCT scan and low-dose MSCT scan of 50 cases with GGN were conducted to observe the shapes,sizes,densities,internal features and boundaries of pulmonary ground-glass nodules. Results： 45 ground-glass nodules were detected through conventional dose MSCT scan and 40 ground-glass nodules were detected through low-dose MSCT scan. The diameter range of the ground-glass nodules was 5 - 20 mm. 26 cases with pulmonary ground-glass nodules were diagnosed as primary lung cancer. Conclusion： Low-dose MSCT scan which can detect pulmonary ground-glass nodules with high accuracy can be used in the screening of early lung cancer.
