CT imaging findings of lung cancer

CT findings of patients with central lung cancer often show bronchial changes, including bronchial wall thickening and stenosis, in addition to hilar masses, bronchial obstruction signs, obstructive emphysema, obstructive pneumonia and obstructive atelectasis. CT can distinguish benign and malignant tumors roughly, and is an important means for the diagnosis of lung cancer at this stage. CT imaging changes in patients with lung cancer play an important role in early screening and diagnosis of lung cancer.
