Abstract

Background: Lung nodules are nodules with a diameter of less than or equal to 30mm, some of which are benign lesions, some are primary malignant, the rest are lung metastatic lesions.¹ The analysis of the imaging characteristics of the opacities allows us to assess the malignancy potential of the opacities and the follow-up strategy for each opacity. Using low-dose CT is considered a method to help early detection and allows image analysis of lung opacities to assess the risk of malignancy of the opacities. Objectives: To evaluate the imaging characteristics of lung opacities on low-dose 128-slice computed tomography. Subjects and methods: 33 patients were screened for cervical cancer by low-dose CT at Hanoi Medical University Hospital. Results: In terms of imaging characteristics, the difference in lung nodule images on low-dose CT and standard-dose CT did not change the strategy for treating pulmonary opacities. Conclusion: Low-dose CT has high value in early screening for lung cancer and reducing radiation dose for patients. Conclusion: Low-dose CT has high value in early screening for lung cancer.
