Besides CT, what other methods can be used to examine lung diseases?

In addition to CT scans, there are many other methods available for examining lung diseases. The most commonly used method is X-ray imaging, which helps doctors identify structural abnormalities and masses in the lungs. Another frequently used technique is pulmonary function testing, which assesses the functional status of the lungs, including lung volume, ventilation function, and gas exchange capacity. Furthermore, blood tests can detect inflammatory responses and tumor markers associated with lung diseases. In pulmonology, physicians may also perform bronchoscopy to examine the airways internally and collect tissue samples for pathological analysis. Finally, doctors can use physical examination methods such as auscultation, palpation, and patient interviews to assist in diagnosing lung diseases.
