For the diagnosis of bronchiectasis, we can rely on the symptoms of the patients such as chronic cough, coughing up large amounts of purulent sputum, repeated hemoptysis, and history of lung infections. Physical examination of the lungs may reveal fixed and persistent localized wet crackles. For auxiliary examinations, we can combine X-ray and CT scans to find imaging changes consistent with bronchiectasis and make a diagnosis. The preferred method for a definitive diagnosis of bronchiectasis is high-resolution CT, and the diagnosis can be made based on the results of a high-resolution CT scan.
