A chest radiograph will be done as an ortho or lateral radiograph. The price of a simple ortho chest radiograph is 70 RMB, a lateral radiograph is also 70 RMB, and both ortho and lateral radiographs are 140 RMB. However, the doctor will recommend a chest CT as the first choice for chest examinations. Although the amount of radiation is greater than that of a chest X-ray, a chest CT reveals lesions more clearly than a chest X-ray and can clearly show whether there are any abnormalities in the lungs. If abnormalities are suspected in the chest X-ray, further chest CT will be done for clarification. At present, screening for early stage lung cancer is done by chest CT, which can be used for low-dose chest CT scan, and the amount of radiation is low, and it can also meet the diagnostic standard.
