PDFAbstract
Objective To explore the application of low dose computed tomography (CT) in the diagnosis of early lung cancer. Methods During the period from February 2016 to June 2017, 100 cases of lung cancer were found in the medical examination center of our hospital and suspected of lung cancer, and then diagnosed as early lung cancer by the oncology department. A total of 48 cases healthy examiner treated with routine dose CT scan were enrolled in the control group, and 52 cases treated with low dose CT scan were included in the observation group. The image quality and nodule detection were compared between the two groups. Results There was no significant difference in image quality between the two group (P>0.05). The dose-length product (DLP) and effective radiation dose (ED) in the control group were higher than those in the observation group (P<0.05). The average diameter of nodules and the number of detected nodules in the observation group were significantly higher than those in the control group (P<0.05). Conclusion Low dose CT can ensure the image quality without affecting the detection rate of early lung cancer and reducing the radiation damage of the subjects.
