Lung CT costs about three to four hundred dollars, depending on the local hospital’s fee schedule and the type of examination machine. Lung CT is an examination of the chest that can clarify the presence and severity of lung lesions, such as inflammation of the lung airways, effusion, lung parenchymal tumors, and pulmonary vascular obstruction. In addition, lung CT is also able to examine the chest wall and diaphragm, heart and other parts of the lesions, to observe the heart with or without coronary sclerosis, cardiac insufficiency and other symptoms. If you have chest pain or coughing and sputum and other symptoms, you can go to the regular hospital for lung CT examination, to clarify the cause of the disease, and under the guidance of the doctor to take appropriate treatment.
