What are the chest imaging techniques used in pt with respiratory disease?

CXR typical (cheap and revealing) but more for outer lesions, for airway more bronchoscopy. we see infiltrations, pleural disease, hilum and mediastinum... we can also use a CT for more sensitivity for small lesions. Chest US is also used bed side (in ICU, out patients) for pleural fluid/ pneumothorax/ pneumonia... other imagings may be used (PET, MRI, angiography)
