In general, CT can determine whether pneumonia or tuberculosis, but cannot rely only on CT manifestations for diagnosis. The CT manifestation of pneumonia is that there are high density foci in the lungs with irregular shapes and edges, and there will be distorted imaging in the lesion area, and this kind of CT manifestation can mostly be diagnosed as inflammation of the lungs. If the patient is a patient with tuberculosis, then there will be more cotton wool or patchy shadows on the ct image. And many radial nodular images can be seen. To determine whether it is pneumonia or tuberculosis, it should not only through the imaging performance, but also according to the history of close contact with tuberculosis patients and other clinical manifestations, such as pneumonia can be accompanied by high fever, chills, while tuberculosis can be accompanied by low-grade fever, night sweats, fatigue and other symptoms. It is recommended to go to a regular hospital to be diagnosed and treated by a doctor.
