Lung CT is about 300~500 dollars. Each hospital has a different level of medical care and charges different rates. If it is a small hospital, the charge may be relatively low, probably around 300 dollars. But if it is a large tertiary hospital, it may cost around $500 for a lung CT. Lung CT is a way of checking whether there are lesions in the lungs by means of imaging, if there is chronic obstructive pulmonary disease, lung tumors, and lung infection with mycoplasma chlamydia and other conditions in the lungs. Thus, in cases of localized pain or dyspnea, the cause of the disease can be identified by means of a CT of the lungs.
