How long does it take to review the pulmonary CT for tuberculosis treatment is mainly based on the severity of the disease and the treatment. It is recommended that the lung CT be repeated after two weeks of treatment because the symptoms will disappear after two weeks of treatment, the infectiousness will disappear, and the lesions will improve on imaging, so a lung CT will be done after two weeks to determine the effect of treatment and adjust the medication according to the situation. If the disease is stable, the interval can be extended to three months after the disease is stabilized, and the lung CT can be repeated every two months.
